 In RX, it maps E1 signals received from the
E1 interface on the front panel to the VC12
of SDH signals, and then performs cross
connection or aggregation through the
aggregation card. In TX, it demaps VC12 of
SDH signals from the aggregation card and
then transmits them to the E1 interface on
the front panel.
 Each E1 supports E1 interface inner
loopback and outer loopback.
