Module for ESCIU Ports
The ESCIU ports (Figure 21) have a different function than the synchronization outputs.
Synchronization outputs provide external reference clock signals for network elements.
ESCIU ports carry El traffic, and directly synchronize the El bitstream.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 El signals that conform to CCITT
G.703 paragraph 6 specifications.
A bypass relay directs the E1 traffic around the ESCIU circuits to maintain continuity on the
spans if a fault occurs.
