SONET/SDH Port Attributes
One OC-3 / STM-1 port is supported on the CMA. One OC-3 / STM-1 port is supported on the
MDA. The ports can be configured for either SONET or SDH operation. SONET ports are
configured for channelized OC-3 operation. SDH ports can be configured for channelized STM-1
operation.
The port’s transmit clock rate can be node or loop timed. The port’s receive clock rate can be used
as a synchronization source for the system. The Section Trace (C1) byte can be configured by the
user to ensure proper physical cabling. The port can activate and deactivate local line and internal
loopbacks.
All SONET/SDH line alarms are configurable to be either enabled (default) or disabled. Link hold
timers can be configured in 100ms increments to control link up and link down indications. The
line signal degradation bit error rate (ber-sd) threshold and the line signal failure bit error rate (ber-
sf) threshold can be configured.
The CMAs and MDAs support all standard SR OC-3/STM-1 SFP optics including multi-mode,
intermediate reach, and long reach. Single fiber mode is not supported.
The CMA contains 3 LEDs for power, status and link state of port #1. The MDA contains LEDs
for power, status and one for each link state. The power LED is blue if power is connected and off
if no power is present. The status LED is green when operationally up, amber when operationally
