Support for 12 DSM

OPTera Metro 3500 Release 12.0 and higher supports 12 protected or
unprotected DSMs. The DSM units could be configured as:

Synchronization

SONET-based equipment derives many of its basic attributes from
synchronous operation. Synchronization is required in networks that contain

OPTera Metro 3500 Multiservice Platform
OPTera Metro 3500 shelves equipped with STX-192 circuit packs (in slots
13 and 14) only supports STS-1 managed DS1 facilities.
OPTera Metro 3500 shelves equipped with VTX-series circuit packs (in
slots 13 and 14) support both VT and STS-1 managed DS1 facilities.
STS-Managed DS1 facilities do not support individual Connection IDs,
instead the STS1 cross connection can be assigned a Connection ID.
Site Manager will support:
— STS-managed circuits.
— VT managed circuits.
— mix of STS & VT managed circuits.
STS-1 managed DSM provisioning data will survive:
— upgrades
— SPx replacement
— Save and Restore operations
You can not provision an STS1 cross connect between DS3 circuit pack to
an STS-1 managed DSM.
You can not provision DS1 facilities on DS1 DSM to DS1 facilities on
channelized DS3 circuit pack using a single STS1-level bandwidth
management command. The channelized DS3 circuit packs is
VT-managed which is not supported by the STS-managed STX-192 circuit
pack.
STS managed only (with STX-192 circuit pack in slots 13 and 14).
STS managed only (with VTX-series circuit packs in slots 13 and 14).
STS or VT Managed combination (with VTX-series circuit packs in slot
13 and 14).
VT managed only (with VTX-series circuit packs in slots 13 and 14 only).
