Module for ESCIU Ports (990-72060-04 System Only)
The ESCIU ports
outputs. A synchronization output provides an all-ones reference clock signals for
network elements. An ESCIU port carries live E1 traffic, and synchronizes the live
traffic as it passes through. The ESCIU module can synchronize 2 spans in one
direction. The return direction passes through as it is.
The ESCIU ports can connect at the digital distribution frame (DDF). The network
elements receiving the ESCIU output signal must be able to receive E1 signals that
conform to CCITT G.703 paragraph 6 specifications. The network element can be
configured to extract its timing from the live E1 traffic signal.
A bypass relay directs E1 traffic around the ESCIU circuitry to maintain span
continuity if a TimeSource 3600 fault occurs.
