This section briefly describes the major hardware related features of the Alcatel-Lucent 1665 DMX.
Below is a list of the sections included in Hardware Features:
Network interface circuit packs (those housed in the MAIN slots of the Alcatel-Lucent 1665 DMX shelf)
Important!
For more detailed information on the capabilities of these circuit packs, see Circuit packs in Chapter 4, Product description. For technical specifications, see Chapter 10, Technical specifications.
The High-Capacity shelf is the current standard Alcatel-Lucent 1665 DMX shelf. This shelf incorporates DS1/E1 and DS3/EC-1 interfaces that were not included in the original design, and enables Alcatel-Lucent 1665 DMX to support 224 DS1s/E1s or 192 DS3s/EC-1s. In order to support this amount of traffic, the High-Capacity shelf must be equipped with high density DS1 and DS3 circuit packs.
The shelf is available in both 20 Amp and 30 Amp versions.
The 20 Amp version of the High-Capacity shelf contains the same functionality as the 30 Amp High-Capacity shelf, but it is limited to a total current drain of 20.0 amps. In applications where the planned equipage will never exceed 20.0 amps, power cables can be sized accordingly, thus enabling a considerable savings in power cable investment.
Important!
With VLF Main packs, overload and overheating in the 20-amp shelf is possible given certain combinations of circuit packs in the low-speed slots. VLF Main packs are not necessarily precluded from use in the 20 Amp shelf, but there are four configurations list in Table 10-106, Current drains that could cause power issues.
Alcatel-Lucent 1665 DMX supports the LNW2 SYSCTL. 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), TL1, CIT, office alarms, and miscellaneous discretes. The SYSCTL also supports DCC terminations for each optical line interface.
This section briefly details the circuit packs currently available to provide or support network interfaces for the Alcatel-Lucent 1665 DMX. This includes all of the high-speed circuit packs, housed in the MAIN slots of the Alcatel-Lucent 1665 DMX shelf, and used to provide the connection to the core-side of the network.
Alcatel-Lucent 1665 DMX supports the following main switch cards:
LNW80: headless pack to facilitate switching amongst multiple tributary interfaces, resides in Main slots, provides no high speed or network side optics, VT mapping in 96 STS-1s, OSP hardened
Alcatel-Lucent 1665 DMX supports the following VLF Main circuit packs, and supports 0x1 port application on these packs:
LNW59 pack supports up to two OC-192 interface and provides a total 140G of Input/Output interfaces. The LNW59 has 180G of usable STS-1 fabric and 30G of usable VT fabric. (The pack could support a 240G STS-1 fabric and a 45G VT fabric with future tributary enhancements.)
LNW82 pack supports up to 8 OC-3 interfaces, 8 OC-12 interfaces, or 2 OC-48 interfaces. Although mixing of interface rates is supported, OC-48 interfaces are only supported on ports 1 and 5. When one of these ports is operating at the OC-48 rate, then the next three adjacent ports cannot be used. The backplane interfaces can operate at 2.5 Gb/s or at 622 Mb/s, supporting all VLF-compatible low-speed packs. The LNW82 provides a total of 110G of Input/Output interfaces. The LNW82 has 130G of usable STS-1 fabric and 10G of usable VT fabric. (The pack could support a 170G STS-1 fabric and a 20G VT fabric with future tributary enhancements.)
LNW504 pack supports up to 4 OC-192 interfaces or up to 3 OC-192 interfaces and 4 OC-48 interfaces. Although mixing of interface rates is supported, OC-192 interfaces are only supported on ports 1–4, and OC-48 interfaces are only supported on ports 5–8. The backplane interfaces can operate at 10 Gb/s and/or 2.5 Gb/s, supporting all VLF-compatible low-speed packs. 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. (The pack could support a 240G STS-1 fabric and a 45G VT fabric with future tributary enhancements.)
Very Large Fabric (VLF) Main circuit packs drastically increase the overall switch fabric capacity of Alcatel-Lucent 1665 DMX. Their ports can be equipped with PTMs. The LNW59 pack supports OC–192 (1.3SR1, 1.5IR2, 1.5LR2, and DWDM) pluggable optics. The LNW82 multi-rate pack supports OC-3 (1.3SR1, 1.3IR1. 1.3LR1 and CWDM) OC-12 (1.3IR1, 1.3LR1, 1.5LR2, and CWDM), or OC-48 (1.3SR1, 1.3LR1, 1.5LR2, and DWDM) pluggable optics. The LNW504 pack supports OC-48 (1.3SR1, 1.3LR1, 1.5LR2, and DWDM) and OC-192 (1.3SR1, 1.5IR2, 1.5LR2, and DWDM) pluggable optics.
VLF cards can also function in headless mode, providing switching and synchronization functionality without being equipped with optics. The VLF packs enable true 0x1 operation among the tributary slots by supporting unprotected 0x1 interfaces located in the same function or growth unit. All tributary circuit packs, with the exception of the LNW7, are supported by the VLF packs.

WDMX is the name of a family of features that adds metro WDM capabilities to the Alcatel-Lucent 1665 DMX product line. WDMX is the integration of WDM functions directly on the Alcatel-Lucent 1665 DMX shelf platform. It adds ITU-T Optical Transport Network (OTN) layered structure for WDM within the shelf footprint.
Alcatel-Lucent 1665 DMX provides WDMX capabilities with the following circuit packs:
LNW785: 8 channel low-loss DWDM Mux/Demux (OMD5/8), with integrated variable optical attenuators (VOAs).
LNW705: PTM-based Muxponder pack (XM10G/8) multiplexes up to 8 ports of high-bandwidth client interfaces (OC-3, OC-12, OC-48 GigE) onto a single 10G wavelength.
The LNW705 and LNW785 must be installed in a shelf with an LNW2 and at least one Main pack. VLF and non-VLF Mains support the WDM packs.
Alcatel-Lucent 1665 DMX supports the following electrical, tributary interface circuit packs:

Alcatel-Lucent 1665 DMX also supports the following hardware:
PTM optics are pluggable optics. Circuit packs using pluggable optics do not come equipped with optics; you can order only the number and type of optics required at the time of installation. Additional optics can then be ordered as new services are required which makes Alcatel-Lucent 1665 DMX interface density scalable to meet the unique needs of each customer. The PTM optics also allow for some versatility in the span lengths and rates that can be covered by the same pack.
PTMs are either SFPs or XFPs. OC-3, OC-12, OC-48, Fast Ethernet, and Gigabit Ethernet ports use optical SFPs. OC-192 port use optical XFPs. Electrical SFPs are also available for Fast Ethernet and Gigabit Ethernet ports The LNW705 (10G Muxponder) packs use SFPs on the 8 client ports and an XFP on the OTU2 port.
The LNW63/64/87/170 packs support dual-function electrical SFPs that are provisionable for 100 or 1000 Mbps (electrical FE or GbE) 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 SFP has a maximum span length of 100 meters.
For OC-48/192 spans of up to 140 km, Alcatel-Lucent offers external optical amplifiers. The external optical amplifier is a stand-alone shelf and can be used with both OC-48 and OC-192 optics.
External optical amplifiers consist of one booster and one pre-amplifier part. The booster part is connected via a Dispersion Compensation Module (DCM) to the transmit interface of the respective OC-192 or OC-48 port unit. The pre-amplifier part is connected by means of a DCM to the receive interface of the associated port unit.
The Alcatel-Lucent Passive Optics Units (POUs) are a lower-cost solution to using DWDM for transmitting large amounts of traffic on one fiber. This module fits into a bay frame, but reduces the number of Alcatel-Lucent 1665 DMX shelves in a bay to three. The box does not require any electrical powering.
POU shelves are available to support the following applications:
Optical add-drop module (OADM): one 1310 nm port and four 1550 nm ports
16 unidirectional/bidirectional wavelengths (2 versions): MUX/DMUX
32 wavelengths; 16 unidirectional/bidirectional wavelengths with a wavelength interleaver used to add another 16 wavelengths: MUXINT/DMUXINT
In the interest of helping customers organize the physical networking in their offices, Alcatel-Lucent 1665 DMX provides a fiber management bracket that mounts to the apparatus blanks used in the unoccupied slots of the shelf. This bracket has hooks where fibers can be set until the pack to which they will be attached is installed. This bracket is available with either 16 or 24 LC fiber storage ports.
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.
This feature is available on both the standard and detectable apparatus blanks and also allows visibility via the CIT.
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 Unit slot (A, B, C, and D) on the Alcatel-Lucent 1665 DMX shelf. 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 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, 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 provides blank cards to be used as fillers in unpopulated slots of the shelf. These fillers help to ensure proper air flow, cooling and EMC safety.
Some blanks can be detected and reported.
Alcatel-Lucent 1665 DMX supports two detectable blank circuit packs: LNW97 in an unequipped M2, LNW98 in unequipped Function and Growth slots.
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.
