Equipping rules

The VTX-48e circuit pack is a double-width circuit pack that is installed in slot
13 and slot 14 of the OPTera Metro 3500 shelf. The OPTera Metro 3500 shelf
must be equipped with VTX48e circuit packs if OC-12 circuit packs are in the
line slots.

Extended shelf processor (SPx)

(NTN423BA, BH)
The extended shelf processor (SPx) provides shelf level control, handles all
shelf communications, and runs the system software. The SPx uses a diskless
storage media for permanent storage of the software load and to record the
network element provisioning and history. RS-232 connections can be made
either to the SPx faceplate connector or to a LOAM connector. System
software resides in the SPx or the network processor nonvolatile memory.
The SPx raises equipment alarms for the co-located extended network
processor (NPx), backs up NPx provisioning data and provides shelf
information and NPx provisioning data to the NPx during an NPx restart.

TL1 sessions

TL1 sessions are hosted by the SPx and all TL1 commands are interpreted by
the processor. Once the commands have been interpreted, the SPx instructs the
dedicated processors in other circuit packs as to what action is to be taken.
OPTera Metro 3500 Multiservice Platform
Note 1: The VTX-48 circuit pack (NTN414AA) only supports the OC-48
line rate in slots 11 and 12.
Note 2: The OC-12 line rate is supported in slots 11 and 12 only if slots
13 and 14 are equipped with VTX-48e circuit packs (NTN414AB or
NTN414AH).
