Main circuit pack descriptions

Overview

This section briefly describes Alcatel-Lucent 1850 TSS-5 main circuit packs, installed in the MAIN 1 and MAIN 2 shelf slots.

10/100/1G-T/F (VLNC40)

The VLNC40 circuit pack is an Ethernet interface unit (EIU) that supports aggregation of Ethernet service. The VLNC40 circuit pack operates unprotected and can only be installed in the MAIN 2 slot of a High Capacity rack-mount shelf.

The VLNC40 circuit pack is compatible with, and its presence is reported by, the VLNC2 SYSCTL circuit pack, if one is present in the shelf. However, the VLNC40 circuit pack is not controlled by a SYSCTL circuit pack, and is not managed by TL1, or through the WaveStar® CIT.

Management and configuration of VLNC40 circuit pack is accomplished using a separate Command Line Interface (CLI). The CLI can be accessed from a serial connection to the VLNC40 through the RS232 port on the VLIU(1,2) associated with the MAIN slot in which the VLNC40 is installed or from the web-based graphical user interface (GUI). The web-based GUI and CLI messages permit VLNC40/42/42B and VLNC60/61/62/64 circuit pack operations to be performed (for example, administration and provisioning).

The VLNC40 is shipped with a default IP address, 169.254.1.1, assigned to the MGMT LAN port on the faceplate of the circuit pack. This address can be set or changed through the RS-232 port on the shelf. The CLI can also be accessed through an IP connection to the MGMT LAN port on the face of the VLNC40 circuit pack, either by direct connection with an Ethernet cross-over cable, or through a network connected to this port. For a detailed description of the Command Line Interface (CLI) messages used to interface with the VLNC40/VLNC42/VLNC42B and VLNC60/VLNC61/VLNC62/VLNC64 circuit packs and general information about using the Command Line Interface (CLI), refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide and the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) CLI User Provisioning Guide.

The VLNC40 circuit pack also has an internal network port. An IP address can be assigned to this internal port, and used for inband access to the CLI from any configured Ethernet port supported by the VLNC40 circuit pack.

Ethernet ports

The VLNC40 circuit pack has 4 100/1000 Mb/s Ethernet ports on the faceplate of the circuit pack. The ports support connections to the Ethernet Access Transport Network (EATN). These ports can be used to externally connect a Gigabit Ethernet link to a VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, or VLNC64 circuit pack. The VLNC40 circuit pack also support a Gigabit Ethernet backplane connection to a VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, or VLNC64 in the same shelf.

If the backplane connection is utilized, the following port is unavailable:

When not using the backplane connection, the ports use pluggable transmission modules (PTMs). They can be plugged into the circuit pack as they become necessary. This allows customers to grow their network incrementally, only realizing the cost of optics when they are needed to provision service. PTM optics are not included when VLNC40 packs are purchased and shipped.

Tributary ports

The VLNC40 circuit pack also supports up to 20 10/100 Mb/s Ethernet ports through RJ45 connectors on the VLIU(1,2) interface unit. The shelf ports provide 10/100 Mb/s links using standard Ethernet switching (IEEE 802.1).

10/100/1G-T/F (VLNC42/42B)

The VLNC42/42B circuit pack is an Ethernet interface unit (EIU) that supports aggregation of Ethernet service. The VLNC42/42B circuit pack operates unprotected and can only be installed in the MAIN 2 slot of a High Capacity rack-mount shelf.

The VLNC42/42B circuit pack is compatible with, and its presence is reported by, the VLNC2 SYSCTL circuit pack, if one is present in the shelf. However, the VLNC42/42B circuit pack is not controlled by a SYSCTL circuit pack, and is not managed by TL1, or through the WaveStar® CIT.

The VLNC42/42B circuit pack also has an internal network port. An IP address can be assigned to this internal port, and used for in-band access to the CLI from any configured Ethernet port supported by the VLNC42/42B circuit pack.

Ethernet ports

The VLNC42/42B circuit pack has 4 100/1000 Mb/s Ethernet ports on the faceplate of the circuit pack. The ports support connections to the Ethernet Access Transport Network (EATN). These ports can be used to externally connect a Gigabit Ethernet link to a VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, or VLNC64 circuit pack. The VLNC42/42B circuit pack also support a Gigabit Ethernet backplane connection to a VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, or VLNC64 in the same shelf.

If the backplane connection is utilized, the following port is unavailable:

VLNC42/42B circuit pack faceplate

The following figure shows the VLNC42/42B faceplate including the following details:

VLNC42/42B circuit pack
OC-3/OC-12/STM-1/STM-4/8DS1E1/3DS3E3/1G (VLNC50)

The VLNC50 circuit pack is a multi-function SONET/SDH transport circuit pack installed in the MAIN 1 and MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC50 circuit pack has two PTM sockets that support OC-3/STM-1 or OC-12/STM-4 optics and one PTM socket that supports Gigabit Ethernet.

Protection

The OC-3/STM-1 or OC-12/STM-4 ports can be used unprotected as 0x1 or provisioned as 1+1 or UPSR/SNCP. The VLIU1 or VLIU10 interface unit is required to support the VLNC50 circuit pack in MAIN2 with equipment protection (UNPROT/PROT).

When UNPROT (protection-not-allowed), protection is between the 2 optical lines on the VLNC50 circuit pack in Main slot 1. The parameter values of Application (0x1 or UPSR/SNCP) and Signal Type (OC-3/STM-1 or OC-12/STM-4) for both optical lines on the circuit pack must be the same value. Unprotected operation is supported in the Main 1 slot only. If a VLNC50 circuit pack is inserted in the unprotected Main 2 slot, the system reports an unexpected CP type alarm.

When PROT (equipment-protection-allowed), each pair of lines across the boards may be a different rate and may be either 0x1, 1+1, or UPSR/SNCP. The two pairs of lines can have different applications.

DS1 and DS3 support

The VLNC50 circuit pack supports up to 8 DS1 ports and 3 DS3 ports via the VLIU(1,2,10) interface unit. The 8 DS1 ports can be cross-connected to VT1.5 timeslots, and 3 DS3 ports can be cross-connected to STS-1 timeslots when the system is operating with a UPSR, 1+1, or 0x1 OC-3 or OC-12 interface. Line build-outs and DS1/DS3 signal encoding are software provisionable. VLNC50 circuit pack supports the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution (B8ZS) modes. DS3 signals are coded using B3ZS.

The VLNC50 circuit pack can be provisioned to support a channelized DS3 signal on port b-3. The channelized DS3 signal can be mapped into 28 DS1 signals. Each of the 28 DS1 signals can be cross-connected to an VT1.5 tributary or a DS1 port. Because these packs support a maximum of 28 DS1s split between the A group and the B-3 group, if a port is used as an electrical DS1 port, the corresponding DS1 port number within the TMUXed DS3 cannot be used. For example, if DS1 port a-1-3 is being used, TMUXed DS1 port b-3-1-3 cannot be used.

E1/E3 support

The VLNC50 circuit pack supports up to 8 E1 ports and up to 3 E3 ports via the VLIU(1,2,10) interface unit.

The 8 E1 ports can be cross-connected to VC-12 timeslots when the system is operating with an SNCP, 1+1, or 0x1 STM-1 or STM-4 interface. The E1 ports have 120 Ohm terminations, and are HDB3-encoded. The mapping is E1 <-> VC-12 <-> TU-12 <-TUG2 <-> TUG3 <->VC-4 <-> AU4. The signals received from the E1 ports are mapped into SDH signals within the VLNC50 circuit pack and then routed to the STM-1 or STM-4 ports.

The 3 E3 ports can be cross-connected to low-order VC-3 timeslots when the system is operating with an SNCP, 1+1, or 0x1 STM-1 or STM-4 interface. The mapping is VC-3 <-> TU3 <-> TUG3 (times 3) <-> VC-4 <-> AU4. The signals received from the E3 ports are mapped into SDH signals within the VLNC50 circuit pack and then routed to the STM-1 or STM-4 ports.

Ethernet

The VLNC50 circuit pack also has a single PTM socket for a Private Line Gigabit Ethernet connection. This port can be used to connect to the LAN port on an Ethernet Aggregator circuit pack (VLNC40/42/42B). If the VLNC50 and VLNC40/42/42B circuit packs are in the same shelf (requires the VLIU1 or VLIU2 interface unit), a Gigabit Ethernet backplane connection between the circuit packs can be provisioned instead of the manual fiber connections on the faceplates. Support for ITU G.7041 for Generic Framing Procedure (GFP), and ITU G.707 for Virtual Concatenation (VCAT) is provided on the VLNC50 for Ethernet over SONET/SDH. The VLNC50 also supports cross-connections from the OC-n/STM-n lines to Fast Ethernet ports on a VLNC35 circuit pack.

OC-3/OC-12/STM-1/STM-4/28DS1E1/3DS3E3/1G (VLNC52)

The VLNC52 circuit pack is a multi-function SONET/SDH transport circuit pack installed in the MAIN 1 and MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC52 circuit pack has two PTM sockets that support OC-3/STM-1 or OC-12/STM-4 optics and one PTM socket that supports Gigabit Ethernet.

Protection

The OC-3/STM-1 or OC-12/STM-4 ports can be used unprotected as 0x1 or provisioned as 1+1 or UPSR/SNCP. The VLIU10 interface unit is required to support the VLNC52 circuit pack in MAIN2 with equipment protection (UNPROT/PROT).

When UNPROT (protection-not-allowed), protection is between the 2 optical lines on the VLNC52 circuit pack in Main slot 1. The parameter values of Application (0x1 or UPSR/SNCP) and Signal Type (OC-3/STM-1 or OC-12/STM-4) for both optical lines on the circuit pack must be the same value. Unprotected operation is supported in the Main 1 slot only. If a VLNC52 circuit pack is inserted in the unprotected Main 2 slot, the system reports an unexpected CP type alarm.

When PROT (equipment-protection-allowed), each pair of lines across the boards may be a different rate and may be either 0x1, 1+1, or UPSR/SNCP. The two pairs of lines can have different applications.

DS1 and DS3 support

The VLNC52 circuit pack supports up to 28 DS1 ports and 3 DS3 ports via the VLIU2 (required if equipping a VLNC40/42/42B in the same shelf) or VLIU10 (required for protection) interface unit. The 28 DS1 ports can be cross-connected to VT1.5 timeslots, and 3 DS3 ports can be cross-connected to STS-1 timeslots when the system is operating with a UPSR, 1+1, or 0x1 OC-3 or OC-12 interface. Line build-outs and DS1/DS3 signal encoding are software provisionable. VLNC52 circuit pack supports the transport of DS1 signals coded in either alternate mark inversion (AMI) or bipolar 8-zero substitution (B8ZS) modes. DS3 signals are coded using B3ZS.

The VLNC52 circuit pack can be provisioned to support a channelized DS3 signal on port b-3. The channelized DS3 signal can be mapped into 28 DS1 signals. Each of the 28 DS1 signals can be cross-connected to an VT1.5 tributary or a DS1 port. Because these packs support a maximum of 28 DS1s split between the A group and the B-3 group, if a port is used as an electrical DS1 port, the corresponding DS1 port number within the TMUXed DS3 cannot be used. For example, if DS1 port a-1-3 is being used, TMUXed DS1 port b-3-1-3 cannot be used.

E1/E3 support

The VLNC52 circuit pack supports up to 21 E1 ports and up to 3 E3 ports located via the VLIU2 (required for the VLNC52) or VLIU10 (required for protection) interface unit.

The 21 E1 ports can be cross-connected to VC-12 timeslots when the system is operating with an SNCP 1+1, or 0x1 STM-1 or STM-4 interface. The E1 ports have 120 Ohm terminations, and are HDB3-encoded. The mapping is E1 <-> VC-12 <-> TU-12 <-TUG2 <-> TUG3 <->VC-4 <-> AU4. The signals received from the E1 ports are mapped into SDH signals within the VLNC52 circuit pack and then routed to the STM-1 or STM-4 ports.

The 3 E3 ports can be cross-connected to low-order VC-3 timeslots when the system is operating with an SNCP, 1+1, or 0x1 STM-1 or STM-4 interface. The mapping is VC-3 <-> TU3 <-> TUG3 (times 3) <-> VC-4 <-> AU4. The signals received from the E3 ports are mapped into SDH signals within the VLNC52 circuit pack and then routed to the STM-1 or STM-4 ports.

Ethernet

The VLNC52 circuit pack also has a single PTM socket for a Private Line Gigabit Ethernet connection. This port can be used to connect to the LAN port on an Ethernet Aggregator circuit pack (VLNC40/42/42B). If the VLNC52 and VLNC40/42/42B circuit packs are in the same shelf, a Gigabit Ethernet backplane connection between the circuit packs can be provisioned instead of the manual fiber connections on the faceplates. Support for ITU G.7041 for Generic Framing Procedure (GFP), and ITU G.707 for Virtual Concatenation (VCAT) is provided on the VLNC52 for Ethernet over SONET/SDH. The VLNC52 also supports cross-connections from the OC-n/STM-n lines to Fast Ethernet ports on a VLNC35 circuit pack.

OC-3/12/48-STM-1/4/16-/28DS1E1-3DS3E3-1G (VLNC55)

The VLNC55 circuit pack is a multi-function SONET/SDH transport circuit pack installed in the MAIN 1 and MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC55 circuit pack has two PTM sockets that support OC-3/STM-1, OC-12/STM-4, or OC-48/STM-16 optics and one PTM socket that supports Gigabit Ethernet.

Protection

The OC-3/STM-1, OC-12/STM-4, or OC-48/STM-16 ports can be used unprotected as 0x1 or provisioned as 1+1 or UPSR/SNCP. The VLIU10 interface unit is required to support the VLNC55 circuit pack in MAIN2 with equipment protection (UNPROT/PROT).

When UNPROT (protection-not-allowed), protection is between the 2 optical lines on the VLNC55 circuit pack in Main slot 1. The parameter values of Application (0x1 or UPSR/SNCP) and Signal Type (OC-3/STM-1, OC-12/STM-4, or OC-48/STM-16) for both optical lines on the circuit pack must be the same value. Unprotected operation is supported in the Main 1 slot only. If a VLNC55 circuit pack is inserted in the unprotected Main 2 slot, the system reports an unexpected CP type alarm.

When PROT (equipment-protection-allowed), each pair of lines across the boards may be a different rate and may be either 0x1, 1+1, or UPSR/SNCP. The two pairs of lines can have different applications.

DS1 and DS3 support

The VLNC55 circuit pack supports up to 28 DS1 ports and 3 DS3 ports via the VLIU2 (required if equipping a VLNC40/42/42B in the same shelf) or VLIU10 (required for protection) interface unit. The 28 DS1 ports can be cross-connected to VT1.5 timeslots, and 3 DS3 ports can be cross-connected to STS-1 timeslots when the system is operating with a UPSR, 1+1, or 0x1 OC-3, OC-12, or OC-48 interface.

Because these packs support a maximum of 28 DS1s split between the A group and the B-3 group, if a port is used as an electrical DS1 port, the corresponding DS1 port number within the TMUXed DS3 cannot be used. For example, if DS1 port a-1-3 is being used, TMUXed DS1 port b-3-1-3 cannot be used.

E1/E3 support

The VLNC55 circuit pack supports up to 21 E1 ports and up to 3 E3 ports located via the VLIU2 (required for the VLNC55) or VLIU10 (required for protection) interface unit.

The 21 E1 ports can be cross-connected to VC-12 timeslots when the system is operating with an SNCP, 1+1, or 0x1 STM-1 STM-4, or STM-16 interface. The E1 ports have 120 Ohm terminations, and are HDB3-encoded. The mapping is E1 <-> VC-12 <-> TU-12 <-TUG2 <-> TUG3 <->VC-4 <-> AU4.

Ethernet

The VLNC55 circuit pack also has a single PTM socket for a Private Line Gigabit Ethernet connection. This port can be used to connect to the LAN port on an Ethernet Aggregator circuit pack (VLNC40/42/42B). If the VLNC55 and VLNC40/42/42B circuit packs are in the same shelf, a Gigabit Ethernet backplane connection between the circuit packs can be provisioned instead of the manual fiber connections on the faceplates. Support for ITU G.7041 for Generic Framing Procedure (GFP), and ITU G.707 for Virtual Concatenation (VCAT) is provided on the VLNC55 for Ethernet over SONET/SDH. The VLNC55 also supports cross-connections from the OC-n/STM-n lines to Fast Ethernet ports on a VLNC35 circuit pack.

8DS1/E1-100/1G-T/F (VLNC60)

The VLNC60 circuit pack provides TDM interface termination for up to 8 DS1/E1 interfaces. It supports CES and ML-PPP termination on a port-by-port basis. These services can be mixed as needed among the ports. The VLNC60 circuit pack is installed in the MAIN 1 or MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC60 circuit pack has a MGMT LAN port on the faceplate and two Ethernet LAN ports with PTM sockets for Fast Ethernet or Gigabit Ethernet connections. Both Ethernet interfaces must be the same rate. The Ethernet port #1 (the right-most port) can be routed as an electrical GbE across the backplane to a companion VLNC40/42/42B circuit pack.

In order to support a Metro Ethernet Forum 8 (MEF-8) based circuit emulation service, the user can specify an option for the mode of Circuit Emulation Service on the pack, either MPLS (RFC 4553) or Ethernet (MEF-8).

By default, the frequency for differential timestamp on the VLNC60 packs is 77.76 MHz. Beginning in Release 5.1, the 25 MHz frequency is supported as well. The frequency must be the same on both ends.

VLNC60 management

The VLNC60 circuit pack is compatible with, and its presence is reported by, the VLNC2 SYSCTL circuit pack, if one is present in the shelf. However, the VLNC60 circuit pack is not controlled by a SYSCTL circuit pack, and is not managed by TL1, or through the WaveStar® CIT. Management and configuration of VLNC60 circuit pack is accomplished using a separate Command Line Interface (CLI). The CLI can be accessed from a serial connection to the VLNC60 circuit pack through the RS-232 port on the VLIU(1,2,10) interface unit associated with the MAIN slot in which the VLNC60 is installed or from the web-based graphical user interface (GUI). The web-based GUI and CLI messages permit VLNC40/42/42B and VLNC60/61/62/64 circuit pack operations to be performed (for example, administration and provisioning). For a detailed description of the Command Line Interface (CLI) messages used to interface with the VLNC40/VLNC42/VLNC42B and VLNC60/VLNC61/VLNC62/VLNC64 circuit packs and general information about using the Command Line Interface (CLI), refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide and the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) CLI User Provisioning Guide.

The VLNC60 is shipped with a default IP address, 169.254.1.1, assigned to the MGMT LAN port on the faceplate of the circuit pack. This address can be set or changed through the RS-232 port on the shelf. The CLI can also be accessed through an IP connection to the MGMT LAN port on the face of the VLNC60, either by direct connection with an Ethernet cross-over cable, or through a network connected to this port.

The VLNC60 also has an internal network port. An IP address can be assigned to this internal port, and used for inband access to the CLI from any configured Ethernet port supported by the VLNC60.

DS1/E1 pseudowire support

The VLNC60 can handle TDM signals for up to 8 DS1/E1 ports. It can encapsulate them into, or extract them from, Ethernet pseudowires. The circuit pack has 2 PTM sockets for pseudowire packet transport. They can be used for interworking with a VLNC40/42/42B Ethernet aggregator (on same shelf, or on another shelf), or for transport directly into the Ethernet Access Transport Network (EATN). The pseudowires corresponding to the DS1 or E1 signals are protected using Bidirectional Forwarding Detection (BFD) protocol.

ML-PPP termination support

DS1/E1 continues to be the predominant Layer-1 technology for IP Backhaul applications, transporting wireless voice and data to and from servers at Mobile Switching Centers (MSCs). The layer 2 protocol used for IP backhaul by the base transceiver station (BTS) universal radio controllers (URCs) is Multi-Link PPP over DS1/E1. The VLNC60 circuit pack can terminate the ML-PPP sessions at the BTS and transmit this IP traffic directly over a packet network using Ethernet 802.1Q encapsulation. The VLNC60 circuit pack interworks between the T1/E1 ML-PPP links from the URC and Ethernet links running 802.1Q encapsulation towards the MSC. This reduces frame overhead associated with data backhaul over DS1/E1, and reduces the number of ML-PPP sessions that must be terminated by the MLS router at the MSC.

16DS1/E1-100/1G-T/F (VLNC61)

The VLNC61 circuit pack provides TDM interface termination for up to 16 DS1/E1 interfaces. It supports CES and ML-PPP termination on a port-by-port basis. These services can be mixed as needed among the ports. The VLNC61 circuit pack is installed in the MAIN 1 or MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC61 circuit pack has a MGMT LAN port on the faceplate and two Ethernet LAN ports with PTM sockets for Fast Ethernet or Gigabit Ethernet connections. Both Ethernet interfaces must be the same rate. The Ethernet port #1 (the right-most port) can be routed as an electrical GbE across the backplane to a companion VLNC40/42/42B circuit pack.

The VLNC61 circuit pack can terminate the ML-PPP sessions at the BTS and transmit this IP traffic directly over a packet network using Ethernet 802.1Q encapsulation. The VLNC61 circuit pack interworks between the T1/E1 ML-PPP links from the URC and Ethernet links running 802.1Q encapsulation towards the MSC. This reduces frame overhead associated with data backhaul over DS1/E1, and reduces the number of ML-PPP sessions that must be terminated by the MLS router at the MSC.

8DS1/E1-100/1G-T/F (VLNC62)

The VLNC62 circuit pack provides TDM interface termination for up to 8 DS1/E1 interfaces. It supports CES and ML-PPP termination on a port-by-port basis. These services can be mixed as needed among the ports. The VLNC62 circuit pack is installed in the MAIN 1 or MAIN 2 slot of the High Capacity rack-mount shelf. The VLNC62 circuit pack has a MGMT LAN port on the faceplate and two Ethernet LAN ports with PTM sockets for Fast Ethernet or Gigabit Ethernet connections. Both Ethernet interfaces must be the same rate. The Ethernet port #1 (the right-most port) can be routed as an electrical GbE across the backplane to a companion VLNC40/42/42B circuit pack.

In order to support a Metro Ethernet Forum 8 (MEF-8) based circuit emulation service, the user can specify an option for the mode of Circuit Emulation Service on the pack, either MPLS (RFC 4553) or Ethernet (MEF-8).

By default, the frequency for differential timestamp on the VLNC62 packs is 77.76 MHz. The 25 MHz frequency is supported as well. The frequency must be the same on both ends.

VLNC62 management

The VLNC62 circuit pack is compatible with, and its presence is reported by, the VLNC2 SYSCTL circuit pack, if one is present in the shelf. However, the VLNC62 circuit pack is not controlled by a SYSCTL circuit pack, and is not managed by TL1, or through the WaveStar® CIT. Management and configuration of VLNC62 circuit pack is accomplished using a separate Command Line Interface (CLI). The CLI can be accessed from a serial connection to the VLNC62 circuit pack through the RS-232 port on the VLIU3 interface unit associated with the MAIN slot in which the VLNC62 is installed or from the web-based graphical user interface (GUI). The web-based GUI and CLI messages permit VLNC40/42/42B and VLNC60/61/62/64 circuit pack operations to be performed (for example, administration and provisioning). For a detailed description of the Command Line Interface (CLI) messages used to interface with the VLNC40/VLNC42/VLNC42B and VLNC60/VLNC61/VLNC62/VLNC64 circuit packs and general information about using the Command Line Interface (CLI), refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide and the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) CLI User Provisioning Guide.

The VLNC62 is shipped with a default IP address, 169.254.1.1, assigned to the MGMT LAN port on the faceplate of the circuit pack. This address can be set or changed through the RS-232 port on the shelf. The CLI can also be accessed through an IP connection to the MGMT LAN port on the face of the VLNC62, either by direct connection with an Ethernet cross-over cable, or through a network connected to this port.

The VLNC62 also has an internal network port. An IP address can be assigned to this internal port, and used for inband access to the CLI from any configured Ethernet port supported by the VLNC62.

DS1/E1 pseudowire support

The VLNC62 can handle TDM signals for up to 8 DS1/E1 ports. It can encapsulate them into, or extract them from, Ethernet pseudowires. The circuit pack has 2 PTM sockets for pseudowire packet transport. They can be used for interworking with a VLNC40/42/42B Ethernet aggregator (on same shelf, or on another shelf), or for transport directly into the Ethernet Access Transport Network (EATN). The pseudowires corresponding to the DS1 or E1 signals are protected using Bidirectional Forwarding Detection (BFD) protocol.

ML-PPP termination support

DS1/E1 continues to be the predominant Layer-1 technology for IP Backhaul applications, transporting wireless voice and data to and from servers at Mobile Switching Centers (MSCs). The layer 2 protocol used for IP backhaul by the base transceiver station (BTS) universal radio controllers (URCs) is Multi-Link PPP over DS1/E1. The VLNC62 circuit pack can terminate the ML-PPP sessions at the BTS and transmit this IP traffic directly over a packet network using Ethernet 802.1Q encapsulation. The VLNC62 circuit pack interworks between the T1/E1 ML-PPP links from the URC and Ethernet links running 802.1Q encapsulation towards the MSC. This reduces frame overhead associated with data backhaul over DS1/E1, and reduces the number of ML-PPP sessions that must be terminated by the MLS router at the MSC.

OC3/OC12-STM1/STM4-100/1G-T/F (VLNC64)

The VLNC64 Circuit Emulation Mini-Hub circuit pack is a variation of the VLNC60 Circuit Emulator circuit pack that performs CES hub and pseudowire functions. Instead of supporting electrical DS1/E1 interfaces, the VLNC64 circuit pack provides a single optical channelized OC-3/STM-1 interface on the TDM side, and two optical FE/GbE interfaces on the Ethernet side. Ethernet interfaces must be the same rate.

The VLNC64 circuit pack performs mapping between DS1/E1 signals recovered from the FE/GbE interfaces and VT1.5/VC-12 tributaries on the channelized OC-3/STM-1 interface. The VLNC64 does not currently support OC-12/STM-4 interfaces. All interfaces support pluggable transmission modules.

The OC-3/STM-1 interface is unprotected (0x1). The OC-3/STM-1 interface does not support DCC. In one direction, the VLNC64 recovers DS1 or E1 signals from the Ethernet LAN inputs, maps them (based on pseudowire provisioning) into VT1.5/VC-12s, which are transported over the OC-3 /STM-1. The opposite occurs in the other direction. The board supports up to 84 circuit-emulated DS1s or up to 63 E1 channels. The pseudowires corresponding to the DS1 or E1 signals are protected using Bidirectional Forwarding Detection (BFD) protocol. BFD is switched based on incoming RDI-L on the OC-3/STM-1, which allows interworking with UPSR/SNCP.

In order to support a Metro Ethernet Forum 8 (MEF-8) based circuit emulation service, the user can specify an option for the mode of Circuit Emulation Service on the pack, either MPLS (RFC 4553) or Ethernet (MEF-8).

By default, the frequency for differential timestamp on the VLNC64 packs is 77.76 MHz. Beginning in Release 5.1, the 25 MHz frequency is supported as well.

Note:

The VLNC64 must be Series 1:2 (S1:2) or later, to support the 25 MHz frequency.
