Chapter 7 Configuring the Channelized 12-port CT3/T1 Optical Services Modules
Supported Features
General Features
The general features are as follows:
•
Channelized DS3 with 28 DS1 lines or 21 E1 lines multiplexed into a DS3 line.
• C-bit parity, M23, and auto-detect framing.
•
Internal clocking configurable.
•
Bit error rate test (BERT) diagnostics for each DS-3 channel
•
Local, line, and remote loopback.
• Generation and termination of DS-3 maintenance data link (MDL) in C-bit framing.
•
Compliance with ANSI T1.231-1993, Bellcore GR820, ANSI T1.107, ANSI T1.403 1989, G.703
Section 2, G.704 Section 3, AT&T Pub. 62411 1990, and Facilities Data Link (ANSI T1.403 and
AT&T 54016).
Serial Encapsulation Protocols
The OSMs support for the following serial encapsulation protocols:
• Point-to-Point Protocol (PPP)
•
Distributed Multilink PPP (dMLPPP)
The OSM-12CT3/T1 module supports dMLPPP, which means that the MLPPP encapsulation is
performed on the OSM-12CT3/T1 module rather than the route processor. The following dMLPP
features are supported:
–
336 bundles per module
– A maximum of 12 DS1/E1 channels per bundle
–
All links in a bundle should operate at the same speed
– 100 ms of differential delay
•
High-Level Data Link Control (HDLC)
• Frame Relay
Configure the OSM-12CT3/T1 interfaces for Frame Relay as described in the Cisco IOS Wide-Area
Networking Configuration Guide, Release 12.1 under “Configuring Frame Relay” and in the Cisco
