User port alarm indication of self-loop DC64K sub-card is inconsistent for
different uplink cards
a. When uplink card is E1 interface, self-loop user port of RC3000-SUB-DC64K sub-card, then LOS
and AIS indicators are in OFF state.
b. When uplink card is optical interface, self-loop user port of RC3000-SUB-DC64K sub-card, then
LOS indicator is in OFF state while AIS in ON state.
The above-mentioned phenomena associated with uplink card type, in such circumstances,
RC3000-SUB-DC64K is trouble-free. When test self-loop, firstly self-loop E1 port, and then
self-loop RC3000-SUB-DC64K sub-card port; when the LOS is in OFF state on
RC3000-SUB-DC64K sub-card; AIS displays in ON state.
