OC-3 PLMs
The OC-3/STM-1 PLM
(Figure A-1)
is a four-port STS-3/STM-1 module that can be plugged
into any of the four slots on a 8820 MSR.
Faceplate Detail
❑
Four independent 155.52 Mbps SONET/SDH STS-3/
STM-1 ports over single-mode fiber, intermediate-reach
(15 Km) or long-reach (40 Km), with LC (SMF) duplex
connector
❑
Channelized OC-3/STM-1 operation (up to three DS3/
STS-1 channels, or one STS-3/STM-1 channel) per port, or
concatenated OC-3c/STM-1c (single STM-1/STS-3c
channel) per port
❑
PPP/ATM/FR/TDM protocols over SONET/SDH per
port
❑
Multiple levels of line and system diagnostic loopback
modes per port
❑
SONET/SDH-compliant with Bellcore GR-253, ITU G.707
and ANSI T1.105-1995
