This section briefly describes Alcatel-Lucent 1665 DMX circuit packs.
The SYSCTL provides communication with other circuit packs on the Alcatel-Lucent 1665 DMX shelf. The SYSCTL supports all Alcatel-Lucent 1665 DMX operations interfaces, including IAO LAN (OSI or TCP/IP), CIT, office alarms, and miscellaneous discretes. The SYSCTL also supports DCC terminations for each optical line interface.
The SYSCTL faceplate has push-button switches, alarm/status LEDs, and a 35-segment numeric LED display to facilitate local operations. Data redundancy is provided by two separate NVMs. Transmission is not affected if the SYSCTL fails.
The SYSCTL circuit pack provides a microprocessor, nonvolatile memory to store the generic program software and provisioning database, and additional memory for system operation. The SYSCTL circuit pack also has interfaces across the backplane to monitor and control every circuit pack in the shelf.
The SYSCTL supports CIT front access to the Alcatel-Lucent 1665 DMX via the IAO LAN and a serial RS-232 port located on the back of the Alcatel-Lucent 1665 DMX shelf.
LNW2 comes equipped with two removable Non-volatile Memory (NVM) cards that can also be ordered separately. An Alcatel-Lucent 1665 DMX shelf will only function properly when it is equipped with an LNW2 card that contains two fully functioning NVM cards. The NVM cards are removable/replaceable.
Note:
The LNW7 circuit pack is not supported when Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59/LNW82/LNW504) circuit packs.
The LNW7 circuit pack contains 28 DS1 ports that can be cross-connected to VT1.5 time slots when the system is operating with a UPSR, 1+1, or BLSR Main interface. Hairpin cross-connections to OC-n and other electrical interfaces are also supported. The circuit pack is 1x1 protected, and non-revertive protection switching is supported. Line build-outs and DS1 signal encoding are software provisionable. The pack terminates up to 28 bidirectional DS1 electrical signals and supports the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution (B8ZS) modes. The signals received from the DSX-1 are mapped into SONET VT1.5 signals and then routed to the high-speed OLIU circuit pack.
The LNW7 circuit pack can occupy Function Unit groups A, B, C, and D. All electric interface circuit packs are 1x1 hardware protected. So, although both slots in each group can house an LNW7 circuit pack, one slot in each group populated by LNW7 circuit packs is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 112 working ports when four Function Unit groups are equipped with the LNW7 circuit pack.
In addition to maintenance and provisioning functions, the 28DS1PM circuit pack provides performance monitoring capabilities.
The LNW8 and LNW801 circuit packs can be used only in the High-Capacity shelf and contain 56 DS1/E1 ports that can be cross-connected to VT or STS-1 time slots in DS1 mode and STS3(c) time slots in E1 mode. The LNW8/LNW801 circuit packs have common functionality and they are directly interchangable. Beginning in Release 9.1, an LNW8 and an LNW801 can occupy companion slots at the same time.
The 56DS1/E1 packs are 1x1 protected by default, and non-revertive protection switching is supported. The LNW8/LNW801 does not support true 0x1 operation. The LNW8 and LNW801 can be used as a protection pair. For unprotected operation, install an LNW8/LNW801 in one slot and leave the companion slot empty. There is no application parameter to provision. The Alcatel-Lucent 1665 DMX does not allow electrical TDM packs (and other packs that require rear access) to be paired with any other working packs in the same Function group or Growth group. For a detailed description of circuit pack equipage guidelines, see Chapter 6, System planning and engineering.
Line build-outs and DS1 signal encoding are software provisionable. These packs terminate up to 56 bidirectional DS1 electrical signals and support the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution (B8ZS) modes. The signals received from the DSX-1 are mapped into SONET VT1.5 signals and then routed to the high-speed OLIU circuit pack. DS1 signals can be connected directly to high-speed BLSRs at the VT1 rate. DS1 Bipolar Violations indicate if the BPV threshold has been exceeded and the DS1 signal incoming from the DSX-1 is being translated to an outgoing far-end DS1 signal LOS or LOF.
The E1 ports have 120 Ohm terminations, and are HDB3-encoded. The mapping is E1 <-> VC-12 <-> TU-12 <-TUG2 <-> TUG3 <->VC-4 (treated as an STS3c). When the LNW8/LNW801 is provisioned for E1 interfaces the output of the card will always be an STS-3c regardless of the amount of traffic it is actually handling.
56DS1/E1 circuit packs can occupy Function Unit groups A, B, C, and D. Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house LNW8/LNW801 circuit packs, one slot in each function group populated by LNW8/LNW801 circuit packs is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 224 working ports when four Function Unit groups are equipped with the LNW8/LNW801 circuit pack.
In addition to maintenance and provisioning functions, the 56DS1/E1 circuit pack provides performance monitoring capabilities.
The 12DS3/EC1 (LNW16) circuit pack contains 12 ports and supports non-revertive protection switching. The 12DS3/EC1 circuit pack provides bidirectional transport of 12 DS3 or EC-1 signals and maps the DS3s into STS-1 signals, and supports transport of DS3 signals coded in bipolar 3-zero substitution (B3ZS). DS3 or EC-1 service is provisionable on a per-port basis within each pack. LNW16 is environmentally hardened for outside plant (OSP) deployments.
The LNW16 does not support 0x1 operation. For unprotected operation, only install an LNW16 in one slot and leave the companion slot empty. There is no application parameter to provision. The LNW16 may occupy Function Unit groups A, B, C, and D. Electrical interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW16 circuit pack, one slot in each function group populated by LNW16 circuit pack is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 48 working ports when four Function Unit groups are equipped with the LNW16 circuit packs.
Alcatel-Lucent 1665 DMX supports a 12-port TransMUX card that can collect various DS1 signals from around a ring and combine them into a channelized DS3 signal. The LNW18 circuit pack is environmentally hardened for outside plant (OSP) deployments.
The LNW18 circuit pack may occupy Function Unit groups A, B, C, and D. Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW18 circuit pack, one slot in each function group populated by LNW18 circuit pack is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 48 working ports when four Function Unit groups are equipped with the LNW18 circuit packs.
The TransMUX circuit pack functions in the following manner:
Transmit Functions
Receive Functions
De-interleaves the STS-1 signal into 28 VT1.5s and interprets VT pointer values
Multiplexes the 28 DS1 signals to an M13 or C-bit formatted DS3 signal
Pre-equalizes the DS3 signal (with LBO) and transmits it to a DSX-3
The 48DS3/EC1 (LNW19B) circuit pack contains 48 ports and supports non-revertive protection switching. The 48DS3/EC1 circuit pack provides bidirectional transport of 48 DS3 or EC-1 signals and maps the DS3s into STS-1 signals, and supports transport of DS3 signals coded in bipolar 3-zero substitution (B3ZS). DS3 or EC-1 service is provisionable on a per-port basis within each pack. LNW19B is environmentally hardened for outside plant (OSP) deployments. The LNW19B supports DS3 terminal loopbacks.
The LNW19B does not support 0x1 operation. For unprotected operation, only install an LNW19B in one slot and leave the companion slot empty. There is no application parameter to provision. The LNW19B may occupy Function Unit groups A, B, C, and D. Electric interface circuit packs are 1x1 hardware protected. So, although both slots in each function group can house an LNW19B circuit pack, one slot in each function group populated by LNW19B circuit pack is always used for hardware protection. Thus the Alcatel-Lucent 1665 DMX shelf supports up to 192 working ports when four Function Unit groups are equipped with the LNW19B circuit packs.
The LNW20 circuit pack provides 48 ports supporting DS3, EC1, and TMUX functionality on a port-by-port basis. Each port can be individually provisioned EC1, ported channelized DS3, ported unchannelized DS3, or portless DS3. With the LNW20, one high-density pack can be used for all DS3, EC1, and/or TransMUX applications. LNW20 can be 1x1 protected or function in 0x1 unprotected mode. It supports hairpins to other packs in the shelf, and between ports on the same pack.
Portless DS3 mode does not utilize any of the electrical ports on the pack. When a port is provisioned for Portless DS3 operation, a channelized DS3 signal within an STS-1 tributary from a SONET interface on a different circuit pack (OC-n or EC-1) or the same circuit pack (an EC-1 on another port) is terminated and demultiplexed into constituent DS1 signals. The DS1 signals are encapsulated into VT1.5 signals and cross-connected at the VT-level within the cross-connection fabric on the Main circuit pack to any other interface that supports DS1 signal transport, including a DS1 interface, a channelized DS3 interface, an EC-1 or OC-n interface. This requires two bidirectional backplane STS-1 signals to convert a single (bidirectional) STS-1 channel.
If the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 circuit packs, portless operation is supported on all LNW20 ports when the circuit pack is installed in any Function/Growth group.
If the Main slots are equipped with large fabric (non-VLF) circuit packs, portless DS3 operation is only supported on the odd ports in the Function/Growth groups. The corresponding even port (odd port plus one) is unavailable.
Unless the Main slots are equipped with large fabric or very large fabric OLIU circuit packs, portless DS3 operation is not supported and any attempts to provision portless DS3 operation are denied.
LNW20 only functions in portless mode in G1/G2 and only large fabric and VLF Mains support portless mode. If other packs are installed in the main slots, the LNW20 cannot be used in G1/G2.

Alcatel-Lucent 1665 DMX does not allow 2 electrical TDM packs of different types (or any packs that require rear access) to occupy adjacent slots in the same Function Group. So, although 0x1 functionality allows LNW20 to function unprotected, overall capacity is not increased. A total of 192 ports are available when all slots are equipped with LNW20 circuit packs (a maximum of 240 ports are available when the LNW20 is functioning in portless mode and the shelf is equipped with VLF Mains). This is because LNW20 must function in portless mode when installed in the Growth Slots. Though the LNW20 supports 0x1 protection, companion slots (ex. A1 and A2) can only be equipped with LNW20 packs (no circuit pack/interface mixing in the same Function Group) providing 1+1 protection.

The LNW37 is hardened for outside plant (OSP) temperature ranges.
The LNW37 features Pluggable Transmission Module (PTM) optics. PTM optics are "pluggable" in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary. LNW37 packs are purchased and shipped with no sockets populated with functioning optics. The ports remain empty until the customer decides to place optics in them.
The LNW37 can occupy any Function Unit group on the Alcatel-Lucent 1665 DMX shelf (including Growth slots), and up to 40 ports are addressable when all Function Unit groups are equipped with the LNW37 circuit pack.

The LNW59 is a 2-port, PTM-based, OC-192 circuit pack. The LNW59 supports OC-192 add/drop, UPSR, and BLSR configurations, single- and dual-homing, and revertive or non-revertive linear 1+1 protection switching. The LNW59 circuit pack provides 2 ports capable of supporting PTMs. It can also function headless (with no optics), similar to the LNW80.
For overall capacity, the LNW59 circuit pack boasts a 20G optical main with a 180G centralized STS switch fabric and 30G VT switch fabric. When Alcatel-Lucent 1665 DMX is equipped with the LNW59 VLF Main, all switching takes place on the LNW59 circuit pack. The switch fabrics on the low-speed, tributary optical circuit packs are disabled. The LNW59 circuit pack further upgrades the shelf's overall capacity by enabling the Function and Growth slots to house circuit packs with up to 10G bandwidth for a total input/ouput capacity of 140G.
The LNW59 circuit pack also enables true 0x1 operation for low-speed packs. It also enables hairpin cross-connections between unprotected 0x1 interfaces located in the same Function or Growth Unit. The LNW59 ports can be provisioned as SONET or SDH using the SS bits detection feature on a per port basis.
The LNW59 circuit pack supports STS-1, STS-3c, STS-12c, STS-48c, and STS-192c signal transport. The OC-192 OLIU can cross-connect VTs in any 192 STS-1s. LNW59s may occupy Main slots 1 and 2.
All tributary circuit packs, except for LNW6 and LNW7, are supported by the LNW59 circuit pack.
The LNW62 is a 4 port OC-48, PTM-based circuit pack supporting add/drop, BLSR, and UPSR configurations, single- and dual-homing, non-revertive or revertive linear 1+1 protection switching, and 0x1 operation. A maximum of 15 BLSRs (between low-speed and high-speed slots) are supported per shelf when the LNW62 is equipped in all tributary slots and VLF Mains are used in the Main slots. The LNW62 ports can be provisioned as SONET or SDH using the SS bits detection feature on a per port basis.
The LNW62 does not have an on-board switch fabric and can only be used with the VLF packs in the Main slots. All switching functions are performed on the VLF Main packs.
LNW62 supports VT1.5, STS-1, STS-3c, STS-12c, and STS-48c signal transport. The LNW62 boasts a 10G backplane interface capacity and may occupy both Function and Growth slots, providing a total port density of 40 OC-48 ports per shelf if all Function and Growth slots are equipped with an LNW62.
The LNW62 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW62 in OSP applications.
The LNW63 circuit pack is a 4-port, PTM-based, Private Line, Gigabit Ethernet pack that supports Gigabit Ethernet optical and electrical PTMs. For specific details about the supported PTM configurations, see Ethernet port configurations. The LNW63 provides data transport at the rate of 1000 Mbps using standard STS-1 virtual concatenation according to ITU G.707.
The LNW63 contains 4 internal WAN ports supporting enhanced Private Line services such as high-order virtual concatenation and Link Capacity Adjustment Scheme (LCAS). These ports have an aggregate capacity of 48xSTS1 (48 STS-1s). Any single port can provide up to 1000 Mbps (subject to this aggregate capacity limitation), but you cannot have each of the 4 ports supporting 1GbE (1000Mbps) service at the same time, because 21 STS-1s per GbE totals 84 STS-1s.
The LNW63 is an unprotected pack.
When Alcatel-Lucent 1665 DMX is not equipped with VLF Main (LNW59/LNW82/LNW504) packs, LNW63 packs can only be placed in Slot 1 of any function group or growth slot in the shelf (A1–G1) and Alcatel-Lucent 1665 DMX supported a total add/drop capacity of 20 Private Line GbE ports if all slots are equipped with LNW63 circuit packs.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main packs, Ethernet packs can occupy both Slot 1 and 2 of a Function or Growth Unit (where applicable). With VLF Mains and all tributary slots populated with LNW63 packs, Alcatel-Lucent 1665 DMX provides a total add/drop capacity of 40 Private Line GbE ports.
When VLF Mains are not used, if the LNW63 circuit packs occupy slot 1 of a Function Unit group. Slot 2 must be populated with an apparatus blank.
The LNW63 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW63 in OSP applications.
The LNW64 circuit pack is an 8-port, PTM-based Private Line Gigabit Ethernet pack. The ports can be populated with either, 8 optical, 8 electrical PTMs, or a mix of 4 electrical and 4 optical PTMs. For specific details about the supported PTM configurations, see Ethernet port configurations. The LNW64 contains 8 internal VCG ports supporting enhanced Private Line services such as high-order virtual concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS). LNW64 supports STS-1 and STS-3c cross-connections with or without VCAT, and STS-12c cross-connections without VCAT. All ports are capable of transmitting at wire speed (1000 Mbps) simultaneously, making full capacity of the pack 168 STS-1s.
The LNW64 is an unprotected pack. The LNW64 can only be used with VLF Mains and can occupy both slots 1 and 2 of a Function/Growth unit, making the total capacity of a system fully populated with LNW64s, 80 GbE Private Line ports.
The LNW64 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW64 in OSP applications.
The LNW66 circuit pack has 24 10/100T Fast Ethernet ports and provides data transport at the rate of 10/100 Mbps using standard Ethernet switching IEEE 802.1, standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707. The LNW66 can transmit signals across spans as long as 100 meters. Each LNW66 circuit pack can support 1 packet ring. The LNW66 is an unprotected pack.
Alcatel-Lucent 1665 DMX does not allow installation of two packs with electrical interfaces in adjacent slots within the same Function Unit or Growth Group (other than an equipment-protected pair). Therefore, in systems equipped with VLF mains, LNW66 packs can reside in either Slot 1 or Slot 2 of a group, but not both at the same time. Telcordia ® only supports electrical packs in Slot 1 of a group. However, another optical (Ethernet or SONET) pack may be installed in the other slot. In non-VLF equipped shelves, LNW66 can only occupy Slot 1 of a particular group. When the LNW66 circuit pack occupies slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
The LNW73 and LNW73C circuit packs are 4-port Storage Area Networking (SAN) interface cards designed to facilitate SAN distance extensions via the Alcatel-Lucent 1665 DMX platform using GFP-T (G.7041). These cards employ standard encapsulation, and standard STS-1 and VT virtual concatenation according to ITU G.707. For extended FC/FICON interfaces, the LNW73/73c also supports buffer_to_buffer credit management spoofing consistent with ANSI T11 FC-BB-3_GFPT draft standard.
They utilize PTM optics to provide the option of FICON, ESCON, or Fibre-channel interfaces natively on the Alcatel-Lucent 1665 DMX shelf. Each circuit pack must be equipped with only one type of PTM (FICON/FC or ESCON). The LNW73/73c can operate at 1 Gbps or 2 Gbps and in either Asynchronous or Synchronous transmission modes. When operating in async Fibre Channel (FC) mode, 2 ports are available at 2Gbps FC, or 4 ports at 1Gbps FC, or 1 port at 2Gbps FC and 2 ports of 1Gbps FC. When operating in synchronous FC mode, 1 port is available at 2Gbps FC, or 2 at 1Gbps FC.
While the capacity of each port is 2Gbps, the true capacity of each port is relative to the type of PTM it is equipped with. For ESCON traffic, the PTM ports have a capacity of 200 Mbps. The 2Gbps capacity of the ports is sufficient to support FC2G and FICON Express.
While the LNW73 and LNW73C circuit packs do support LCAS, the LNW73 only uses LCAS with asynchronous FC traffic.
The LNW73C circuit pack differs from the LNW73 circuit pack in that it enables compression of SAN traffic.
The implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
The LNW73C circuit pack is able to compress asynchronous Fibre Channel traffic and conserve up to 50% of bandwidth versus uncompressed asynchronous FC traffic in typical applications.
Compression for asynchronous FC traffic is pre-standard and will be standardized by FC-BB-4. The R6.0 implementation of SAN compression enables a high throughput of up to two full-line rate FC-2G interfaces in a single pack.
When Alcatel-Lucent 1665 DMX is not equipped with VLF Main (LNW59/LNW82/LNW504) circuit packs, the LNW73/73C circuit packs can only occupy slot 1 of any Function or Growth Unit group on the shelf. When Alcatel-Lucent 1665 DMX is equipped with VLF circuit packs in the Main slots, FC-DATA circuit packs can occupy both Slot 1 and 2 of a Function or Growth Unit.
When VLF Mains are not used, if the LNW73/73C circuit packs occupy slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
This LNW74 is a 24-port Fast Ethernet Private Line circuit pack. The LNW74 uses standard GFP encapsulation (G.7041) and standard STS-1 and VT virtual concatenation according to ITU G.707. The LNW74 circuit pack provides 8 ports for optical 100BASE-ZX/LX/FX transport at 100 Mbps The LNW74 circuit pack also provides 16 electrical ports for the 10/100BASE-T interfaces. These electrical ports transmit at 10/100 Mbps using standard Ethernet switching IEEE 802.1, standard encapsulation, and standard STS-1 and VT virtual concatenation according to ITU G.707. For specific details about the supported configurations, see Ethernet port configurations. The LNW74 circuit pack electrical interfaces can transmit signals across spans as long as 100 meters.
The LNW74 circuit pack is an unprotected circuit pack and is OSP hardened. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW74 in OSP applications.
The LNW74 circuit pack is designed specifically to support Fast Ethernet Private Line applications. Each LNW74 circuit pack can support 24 private lines. The LNW74 circuit pack can also support STS-3(c) cross-connections instead of virtual concatenation.
When the Main slots are equipped with VLF circuit packs, LNW74 circuit packs can be installed in either slot 1 or 2 of Function Unit or Growth groups to support true 0x1 on optical ports. The LNW74 circuit pack can be installed next to another optical TDM or Ethernet circuit pack within the same group.
When VLF Mains are not used, if the LNW74 circuit packs occupy slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank.
The LNW74 circuit pack features Pluggable Transmission Module (PTM) optics for all 100BASE-ZX/LX/FX interfaces. PTM optics are "pluggable" in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary. LNW74 circuit packs are purchased and shipped with no ports populated with functioning optics. The ports remain empty until the customer decides to place optics in them. 8 ports are available for 100BASE-ZX/LX/FX optics. There are 24 internal WAN ports (capable of transmitting signals to the MAIN circuit packs) in the LNW74 circuit pack.
The LNW76 high-speed circuit pack is a short-reach, OC-48 1310 nm optical line interface unit. It is designed for intra-office transmission. The LNW76 supports OC-48 add/drop, BLSR, UPSR, and 1+1 configurations, single- and dual-homing, non-revertive linear and bidirectional 1+1 protection switching, and VT1.5, STS-1, STS-3(c), STS-12(c), and STS-48(c) signal transport. The Stratum 3 timing generator and central TDM switch fabrics are embedded in the OC-48 OLIU.
The LNW76 circuit pack can cross-connect VTs in all 48 STS-1s of the OC-48 signal.
The LNW76 may occupy Main slots 1 and 2. Fiber access is provided via a pair of LC-type connectors on the LNW76 faceplate.
The LNW80 high-speed circuit pack is designed to save cost in CO hub applications where there is no need to transmit traffic over network-side interfaces. LNW80 is best used in a DCS type of application. It can cross-connect signals amongst multiple low-speed tributary interfaces and perform VT mapping into OC-3/12/48 tributaries. It can cross-connect signals at the VT1.5, STS-1, STS-3(c), STS-12(c), and STS-48(c) level. The Stratum 3 timing generator and central TDM switch fabrics are embedded in the LNW80.
The LNW80 circuit pack design is based on the design/capabilities of the LNW27 pack, minus the optical interfaces.
The LNW80 circuit pack supports VT mapping in 96 STS-1s.
The LNW80 may occupy Main slots 1 and 2 and contains NO interfaces on the faceplate of the pack. Due to the increased switch fabric size and the absence of any optics on the pack's faceplate, the LNW80 cannot be upgraded to a high-speed optical pack.
The LNW82 high-speed circuit pack is an 8-port, multi-port., multi-rate (MPMR) OC-3, OC-12, OC-48 VLF Main circuit pack. The pack supports a maximum of 8 OC-3 interfaces, 8 OC-12 interfaces or 2 OC-48 interfaces and has integrated STS and VT fabrics.
Mixed interface rates are supported with the following restrictions.
When one of these ports is operating at the OC-48 rate, then the next three adjacent ports cannot be used.
For example, if port 1 is operating as an OC-48 port, then ports 2, 3, and 4 are unavailable for use.
The LNW82 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW82 in OSP applications.
The pack supports true 0x1 operation for low-speed packs. The backplane interfaces can operate at 2.5 Gb/s or at 622 Mb/s, supporting all VLF-compatible low-speed packs. The LNW7 circuit pack is not VLF-compatible.
The overall capacity of the LNW82 is a 10G optical main with 130G of STS switch fabric and 10G VT switch fabric. When the Alcatel-Lucent 1665 DMX is equipped with LNW82 VLF mains, all switching takes place on the LNW82 circuit packs. The switch fabrics on the low-speed, tributary optical circuit packs are disabled. The LNW82 further upgrades the overall capacity of the shelf by enabling the Function and Growth slots to house circuit packs with up to 10G bandwidth for a total input/output capacity of 110G.
The LNW82 provides increased flexibility for equipping low-speed OC-n interfaces with increased port density. OC-3, OC-12, OC-48, or OC-192 operation can be selected on a per port basis, up to the maximum number of ports supported for each interface type. The supported protection applications (1+1, 1+1_BIDIR, 1+1_OPTM, UPSR, 0x1, and BLSR [OC-48 only]) can also be provisioned on a per-port basis. The LNW82 ports can be provisioned as SONET or SDH using the SS bits detection feature on a per port basis.
The LNW87 circuit pack is an 4-port, PTM-based Private Line Fast Ethernet/Gigabit Ethernet pack. The ports can be populated with either, 4 optical, 4 electrical PTMs, or a mix of electrical and optical PTMs. The port mode is provisionable on per port basis. The LNW87 contains 4 internal VCG ports supporting enhanced Private Line services such as high-order virtual concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS). LNW87 supports STS-1 and STS-3c cross-connections with or without VCAT, and STS-12c cross-connections without VCAT. All ports are capable of transmitting at wire speed (1000 Mbps) simultaneously, making full capacity of the pack 84 STS-1s.
The LNW87 is an unprotected pack. The LNW87 can be used with VLF Mains or non-VLF mains and can occupy both slots 1 and 2 of a Function/Growth unit, making the total capacity of a systems fully populated with LNW87s, 40 GbE Private Line ports.
The LNW87 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW87 in OSP applications.
Alcatel-Lucent 1665 DMX supports a circuit pack designed to aid technicians in the installation and maintenance of Electrical interfaces and cables. The Electrical Continuity Test Tool (LNW94) can be placed in any Function slot on the Alcatel-Lucent 1665 DMX shelf (NOT including Growth Slots). It is used to test the cables which will be connected to DS1, DS3, or Ethernet electrical interfaces. LNW94 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up.
The In-service Electrical Continuity Test Tool (LNW93) test circuit pack is used for upgrades in the Alcatel-Lucent 1665 DMX High-Capacity shelf. An in-service shelf might have a function unit with low capacity DS1 (LNW7) or DS3 (LNW16) packs. When these packs are upgraded with higher capacity packs (DS1, LNW8/LNW801; DS3, LNW19B), as part of the upgrade procedure, new DS1 or DS3 connectorized cables are added to the DSX cross-connect frames and to the Alcatel-Lucent 1665 DMX shelf. The LNW93 pack is used to test out the new wiring without disrupting traffic on the in-service pack.
The LNW93 is very similar to the LNW94 test tool except that it has no backplane connectors for DS1 ports #1–28 or for DS3 ports #1–12. When the LNW93 is plugged in, it makes no contact with the wires on the backplane for those lower ports. Since there is no physical connection, the LNW93 does not interfere with the service of the pack in the other slot of the function unit. The LNW93 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up of a high density DS1 or DS3 circuit pack.
Alcatel-Lucent 1665 DMX supports detectable blank circuit packs: LNW98 in unequipped Function and Growth slots, LNW97 in an unequipped M2.
The WaveStar® CIT reports the presence of a detectable blank in a slot by displaying a blank faceplate graphic instead of an empty slot graphic. No alarms are associated with the insertion or removal of the detectable blank.
The LNW170 circuit packs provide four IEEE 802.3-compliant (1000Mbps) GbE interfaces and four IEEE 802.3-compliant (100 Mbps) fast Ethernet interfaces. The LNW170 circuit packs provide Ethernet private line or switched services, with QoS.
The LNW170 packs feature Pluggable Transmission Module (PTM) electrical and optical interfaces. PTMs are "pluggable" in the sense that they can be plugged into a circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the full cost for optics as the need to provision service on (and thus receive revenue from) them becomes necessary. LNW170 packs are purchased and shipped with no ports populated with functioning optics. The ports remain empty until the customer decides to place interfaces in them.
The LNW170 supports dual function electrical PTMs that are provisionable for 100 or 1000 Mbps traffic. They conform to the IEEE802.3 standards for 100BASE-T and 1000BASE-T in the respective settings (IEEE802.3z and IEE802.3ab). Connectivity is provided for an RJ-45 Cat 5 cable and the PTM has a maximum span length of 100 meters.
The electrical FE (100BASE-T) PTMs can occupy ports 1–8. The GbE (1000BASE-T/X) PTMs are restricted to ports 1–4. For specific details about the supported configurations, see Ethernet port configurations.
The LNW170 packs use standard Ethernet switching (IEEE 802.1), standard encapsulation, and standard STS-1 virtual concatenation according to ITU G.707. Fiber access is provided by LC-type connector pairs on the LNW170 faceplate.
The LNW170 packs are unprotected by default. Support of Link Aggregation on LNW170 LAN ports is available to provide Ethernet facility protection. The LNW170 also supports aggregation across LNW170 circuit packs to provide equipment protection. For more information, see Link aggregation (LNW170 LAN ports), in Appendix A, Ethernet/SAN.
When Alcatel-Lucent 1665 DMX is not equipped with VLF Main packs, unprotected LNW170 packs can only occupy slot 1 of any Function Unit group on the shelf (including Growth slots). Up to 20 1000BASE-X and 20 100BASE-ZX/LX/FX ports are addressable when all Function Unit groups are equipped with unprotected LNW170 circuit packs.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main packs, LNW170 packs can occupy both Slot 1 and 2 of a Function or Growth Unit. With VLF Mains and all tributary slots are populated with LNW170 packs, up to 40 1000BASE-SX/LX/ZX and 40 100BASE-ZX/LX/FX ports are addressable.
When VLF Mains are not used, if unprotected LNW170 circuit packs occupy slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank. When set to equipment-protected, two LNW170s can also be in the same group
The LNW202 high-speed circuit pack is a PTM-based optical line interface unit. The LNW202 supports OC-48 add/drop, BLSR and UPSR configurations, single- and dual-homing, non-revertive linear and bidirectional 1+1 protection switching, and VT1.5, STS-1, STS-3(c), STS-12(c), and STS-48(c) signal transport.

The LNW402 circuit pack may occupy any Function Unit group on the Alcatel-Lucent 1665 DMX shelf (including Growth slots), and up to 10 ports are addressable when all Function Unit groups are equipped with the LNW402 circuit pack.
The LNW504 high-speed circuit pack is an 8-port, multi-port., multi-rate (MPMR) OC-48/OC-192 VLF Main circuit pack. LNW504 pack supports up to 4 OC-192 interfaces or up to 3 OC-192 interfaces and 4 OC-48 interfaces and has integrated STS and VT fabrics. The LNW504 circuit pack supports STS-1, STS-3c, STS-12c, STS-48c, and STS-192c signal transport.
Note:
Because the four OC-48 lines and the fourth OC-192 line share the same internal resources, the operation of OC-48 lines 5–8 is mutually exclusive of the operation of OC-192 line 4.
Mixed interface rates are supported with the following restrictions.
Note:
The LNW504 faceplate port numbering starts from the bottom of the pack. Port 1 is at the bottom and port 8 is at the top.
The LNW504 is hardened for outside plant (OSP) temperature ranges. However, you must install PTMs that are approved for industrial temperatures (OSP hardened) to use the LNW504 in OSP applications.
The pack supports true 0x1 operation for low-speed packs. The backplane interfaces can operate at 10 Gb/s and/or 2.5 Gb/s, supporting all VLF-compatible low-speed packs. The LNW7 circuit pack is not VLF-compatible.
The LNW504 provides a total of 180G of Input/Output interfaces. The LNW504 has 220G of usable STS-1 fabric and 30G of usable VT fabric. When the Alcatel-Lucent 1665 DMX is equipped with LNW504 VLF mains, all switching takes place on the LNW504 circuit packs. The switch fabrics on the low-speed, tributary optical circuit packs are disabled. The LNW504 further upgrades the overall capacity of the shelf by enabling the Function and Growth slots to house circuit packs with up to 10G bandwidth for a total input/output capacity of 110G.
The LNW504 provides increased flexibility for equipping low-speed OC-n interfaces with increased port density. OC-48 or OC-192 operation can be selected on a per port basis, up to the maximum number of ports supported for each interface type. The supported protection applications (1+1, 1+1_BIDIR, 1+1_OPTM, UPSR, 0x1, and BLSR [OC-48 only]) can also be provisioned on a per-port basis. The LNW504 ports can be provisioned as SONET or SDH using the SS bits detection feature on a per port basis.

The LNW705 XM10G/8 Muxponder circuit pack is a highly integrated pack that multiplexes up to 8 ports of the most common high bandwidth client interfaces onto a single 10G wavelength. The circuit pack name is XM10G/8: the “X” indicates that the client ports can be SONET/SDH, 1GE or Fibre Channel type interfaces; the “M” represents multiplexer; the “10G” represents the 10G line-side interface; the “8” represents the 8 client ports.
The XM10G/8 circuit pack is 25 mm wide and transports up to 8 client ports. The ports can be a mix of the following signals: 1GE, FC100, FICON, FC200, FICON_EXP, or OC3/12/48. One GE is mapped using VCAT and GFP-F. All FC signals and FICON signals are mapped using VCAT and GFP-T. The client signals are mapped into a single STS-192 and then encoded into an OTN OTU-2 signal (including forward error correction) and is transmitted out on a DWDM XFP. The circuit pack is bi-directional and simultaneously handles the inverse function in the receive direction.
The circuit pack faceplate is equipped with standard LED indicators; 1 fault LED, 1 active LED, and 1 LED for each port.
The LNW705 must be installed in a shelf with an LNW2 and at least one Main pack (VLF or non-VLF).
The LNW705 may occupy any Function Unit or Growth slot on the Alcatel-Lucent 1665 DMX shelf.
Beginning in Release 9.1, the Forward Error Correction (FEC) mode for an OTU2 port is provisionable. Valid values are:
The LNW785 circuit pack provides optical multiplexing and demultiplexing of 8 dense-wavelength-division-multiplexed (DWDM) channels (ITU-T channels 52 through 59 [195.20-195.90 THz]). The LNW785 circuit pack has variable optical attenuators (VOAs) on the inputs for individual channel-power control. It can perform automatic channel power balancing of the add channels via the VOAs.
The LNW785 circuit pack allows Alcatel-Lucent 1665 DMX to have channel-power-managed DWDM within the shelf. The LNW785 circuit pack can be installed in any Alcatel-Lucent 1665 DMX function or growth slots. A one-channel system can be upgraded to an 8-channel-capable system by installing one or more LNW785 circuit packs into any open function or growth slot.
The LNW785 circuit pack requires the use of extended shelf covers for Alcatel-Lucent 1665 DMX shelves, which provide 25-mm additional clearance (67-mm total) as opposed to the current shelf covers. This is because additional clearance is required to angle the multiple connectors on this card.
The LNW785 circuit pack is the first Alcatel-Lucent 1665 DMX circuit pack with intra-shelf fiber routing. Special short jumpers are used to connect pass-through channels when two LNW785 circuit packs in adjacent slots are used as an optical add-drop multiplexer (OADM).
The LNW785 must be installed in a shelf with an LNW2 and at least one Main pack (VLF or non-VLF).
The following 1-way optical cross-connections are supported on the OCH interfaces of the LNW785 series.
For cross-connections to or from OCH ports, the NE checks that the expected frequency of the port to which the OCH is cross-connected matches the frequency of the OCH port. However, frequency matching is not required on cross-connections between an OCH port and an alien port.
In the interest of helping customers organize the physical networking in their offices, Alcatel-Lucent 1665 DMX provides two types of fiber management brackets that mount to the apparatus blanks used in the unoccupied slots of the shelf. These brackets have LC fiber storage ports where fibers can be set until the pack to which they will be attached is installed. One bracket has 16 hooks and the other has 24 hooks.
The bracket is designed to facilitate the organization and storage of pre-wired fibers that are expected to carry service to the shelf in the future. These brackets attach to the apparatus blanks via PEM nuts on the faceplate. PEM Nuts or PEM Fasteners are mounted flush on the faceplate. They provide a fixed receptacle to which the bracket can be screwed in.
