Dual speed OC-12c and OC-48c POS interface modules
Dual-speed OC-48c or OC-12c POS interface modules can be reconfigured through the CLI to
support OC-48 or OC-12 speeds.
The front panels of OC-12c and OC-48c POS interface modules contain the following features:
•
Two, four, or eight ports that can accommodate SFP optics.
•
A power LED to indicate if power is being received by the module.
•
Four LEDs per port that indicate the following port states: Active or Local Fail, TX Pkt, RX Pkt,
and Carrier Rcvd or Remote Fail.
•
Two IN and two OUT RJ-48 connectors to provide a BITS external clock source and to propagate
a common clock source (Line or BITS) among POS modules.
Figure 26
,
Figure 27
, and
Figure 28
illustrate these features.
