Main circuit packs

This section briefly describes the circuit packs supported in the MAIN1 and MAIN2 slots.

One faceplate Ethernet port may instead be provisioned to use a backplane connection at the Gigabit Ethernet rate to a VLNC40, VLNC42, or VLNC42B in the shelf.

The VLNC61 Circuit Emulator circuit pack may be installed in the MAIN1 or MAIN2 slot. The VLIU2 or VLIU10 interface unit is required to support the additional DS1/E1 interfaces on the VLNC61 circuit pack.

VLNC62 Circuit Emulator circuit pack

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.

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).

The VLNC62 circuit pack faceplate can be equipped with up to 2 pluggable transmission modules for packet transport.

One faceplate Ethernet port may instead be provisioned to use a backplane connection at the Gigabit Ethernet rate to a VLNC40, VLNC42, or VLNC42B in the shelf.

The VLNC62 is hardware-enabled to support the Time of Day (ToD)/1PPS feature for GPS replacement applications. The VLNC62 supports 1588 SYNC distribution with or without a GPS input. A option is available in CLI and Web GUI to configure the pack in ToD or non-ToD (without GPS) mode.

The VLNC62 Circuit Emulator circuit pack may be installed in the MAIN1 or MAIN2 slot. The VLIU1, VLIU2, or VLIU3 interface unit is required to support the VLNC62 circuit pack. The VLIU3 interface unit is required if Time of Day is desired.

VLNC64 Circuit Emulation Mini-Hub circuit pack

The VLNC64 Circuit Emulation Mini-Hub circuit pack is a variation of the VLNC60 Circuit Emulator circuit pack that performs Circuit Emulation functions. Instead of supporting electrical DS1/E1 interfaces, the VLNC64 circuit pack provides a single optical channelized OC-3/STM-1interface on the TDM side, and two optical FE/GbE interfaces on the Ethernet side. All interfaces support pluggable transmission modules.

The OC-3/STM-1 interface is unprotected (0x1). 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.

The VLNC64 Circuit Emulation Mini-Hub may be installed in the MAIN1 or MAIN2 slot. It is compatible with all interface units (VLIU[1,2,3,10]). When installed in MAIN1, the VLNC64 circuit pack may work with a VLNC40/42/42B circuit pack in the adjacent MAIN 2 slot. The VLNC64 simultaneously provides SyncE timing output signal to the backplane for the adjacent circuit pack (SyncE transmit mode) and differential interface timing (for DS1/E1 ports) used in circuit emulation applications. The VLNC64 circuit pack also interworks at the far end of the Ethernet links with multiple, aggregated VLNC60/61/62 circuit packs. The optical OC-3/STM-1 interface is intended for connecting to an external DACS or ADM.

Function Group C circuit packs

Circuit packs installed in the Function Group C slot are associated with the shelf Group C electrical interfaces.

VLNC33 circuit pack that supports up to 3 optical Fast Ethernet (100BASE-LX) ports and serves as an extension for the VLNC42B circuit pack. The VLNC33 is only supported when the VLNC42B is inserted in the Main2 slot; the VLNC33 is not supported if any other pack is installed in the shelf other than the VLNC42B in Main 2.

VLNC35 Fast Ethernet Private Line circuit pack that supports up to 4 electrical Fast Ethernet (10/100BASE-T) ports and 2 optical Fast Ethernet (100BASE-X) ports and works with the VLNC50/52/55 SONET/SDH Transport circuit packs in Ethernet over SONET/SDH applications.

Pluggable transmission modules (PTMs)

The VLNC33, VLNC35, VLNC40, VLNC42/42B, VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, and VLNC64 circuit packs support pluggable transmission modules (PTMs). They are purchased separately from the circuit pack and equipped (or plugged in) only as additional interfaces become necessary. PTMs make Alcatel-Lucent 1850 TSS-5 interface density scalable and can lower initial costs.

CWDM pluggable transmission modules are available for VLNC40, VLNC42/42B, VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, and VLNC64 circuit packs.

Forced laser shutdown

The Forced laser shutdown feature allows the user to override normal laser operation and manually shut down the laser by enabling the feature on a per-port basis. The feature is operated through the WebGUI.

The feature is supported on optical faceplate PTM ports on:

The feature is not supported on the VLNC33, VLNC40, VLNC42, VLNC60, or the VLNC42B in Bridged mode.

The laser shutdown feature can be used for remote diagnostic testing. A user can remotely turn off a laser and verify that the far end detects the LOS.

When forced laser shutdown is enabled, laser is OFF When forced laser shutdown is disabled, current laser operation is in effect .

The NE restores normal laser operation for each PTM under each of the following conditions.
