3.1.2 E1 connection board
The E1 connection board provides connections for the internal and external E1 wiring
and for alarms.
The external E1 interfaces A1 and B1 (refer to Figure 3.12, are routed via an E1 relay
and serve to connect further network elements connected in the form of a ring. If a TIB
transceiver module fails, the E1 relay is disabled and the incoming E1 connection is
directly looped on to the next network element.
Figure 3.12 shows the top view of the E1 connection board. The following table
describes these indicators in detail.
