FIGURE 28 8-port OC-12c and OC-48c POS interface module
Single-Speed OC-192c POS interface modules
The front panel of the single-speed OC-192c POS interface modules contain the following features:
• One or two ports that accommodate XFP optics.
• An LED that indicates if power is being received by the module.
• Four LEDs per port that indicate the following port status: Active or Local Rail, TX Pkt, RX Pkt,
and Carrier Rcvd or Remote Fail.
• Two IN and two OUT RJ-48C connectors to provide a BITS external clock source and to
propagate a common clock source (Line or BITS) among POS modules.
Figure 29, and Figure 30 illustrate these features.
