Network Management - Cisco OSM-12CT3/T1 - Optical Services Module Multiplexor Configuration

Chapter 7 Configuring the Channelized 12-port CT3/T1 Optical Services Modules
•
For channelized, fractional, and unframed configurations each configured channel group, which might
Note
contain individual timeslots and/or ranges of timeslots, uses only one of the 128 available logical
channels. For example, if you assign the range of timeslots 3-7 to a channel group, only one logical
channel is used. Likewise, if you assign just timeslot 3 to a channel group, only one logical channel is
used.

Quality of Service Protocols
For information on configuring QoS on the Channelized OSMs, refer to
on the Optical Services Modules."
The following QoS features are supported on the Channelized OSMs:

OL-9465-03
Fractional E1 lines contain only a single logical channel group that can be either a single 64-kbps
timeslot or a range of timeslots; for example timeslot 1, or timeslots 15-23. Any unused timeslots
are filled with programmable idle-channel data.
Note If you assign only one channel group to an E1 line, it is a fractional E1 line. If you assign
more than one channel group to an E1 line, it is a channelized E1 line.
Unframed E1—Any of the 21 E1 lines can be configured as unframed E1 data lines. Each unframed
E1 line contains no framing overhead and is not timeslot divided.
