•
Inband Management Bandwidth is the sum of the SYNC Rate and the Overhead Rate. User
selectable rates are:
•
SYNC: 200, 400, 800, 1600 bps (default is 200 bps)
•
OVERHEAD: 400, 1200, 4800, 9600, 19200 bps (default is 9600 bps)
•
Optional Maintenance Console - In the event of aggregate link outage, a PC equipped with
"Hyperterminal" or equivalent software package with VT-100 terminal emulation features can
be plugged into the remote OCM to validate status and perform local diagnostics. This optional
feature allows support (but not configuration) of Local Channel Loopback, Local Aggregate
Loopback including and excluding Line Interface Module, as well as local Alarm reporting.
OCM-2000 Special Features
In addition to the common features listed above, the OCM-2000 provides the following special
features:
•
OCM-2000 acts as a feeder multiplexer to the TMS-3000 using CDA or IAC.
•
CDA/T1/E1 allows termination of up to 32 OCM-2000 tail nodes.
•
The OCM-2000 communicates to the TMS Controller via a supervisory communication path.
Configuration is downloaded from the TMS Controller. OCM supports TMS status, alarms and
diagnostics.
•
TMS circuits originating at OCM-2000 channels pass through CDA subaggregates to terminate
in TMS channels or other OCM channels.
OCM-1000 Special Features
In addition to the common features listed above, the OCM-1000 provides the following special
features:
•
OCM-1000 acts as a point-to-point, point-to-multipoint access multiplexer, independent of a
TMS network.
•
Supports subrate LIM at rates of 9.6 to 64 kbps.
•
Controlled by PC-based controller, via OCM Management Software (OMS).
