Section trace for OC-48
OPTera Metro 3500 supports section trace capability for OC-48 services.
Section trace provides a diagnostic tool that can determine installation and
commissioning problems such as misconnected optical fibers. Section trace
occupies the J0 SONET byte (formerly known as the C1 byte to indicate the
STS-1 ID) of the section overhead. Section trace is injected at the transmit end
of a section and extracted at the receive end where it can be checked against an
expected section trace value.

Section data communication channel (SDCC)

An OC-48 line carries a DCC channel that can be edited, provisioned, and
deprovisioned.

Equipping rules

The OC-48 optical interface circuit pack can be installed in slots 11 and 12.
See
An OPTera Metro 3500 network element with a protected OC-48 line rate
requires two OC-48 circuit packs in slots 11 and 12 of each shelf.
OPTera Metro 3500 Multiservice Platform
Note 1: The maximum number of simultaneous SDCC-provisionable
ports on an OPTera Metro 3500 shelf is 34 (the shelf must be equipped with
eight unprotected OC-3x4 circuit packs in slots 3 through 10, and a
protected pair of OC-48 circuit packs in slots 11 and 12).
Note 2: For Nortel Networks interworking and multi-vendor network
scenarios, DCC interoperability can be achieved with the appropriate
provisioning. See Optical Networks Data Communications Network
Planning Guide, NTR710AM.
