Loopbacks
The OME6130 supports loopbacks on STM-1/4, 10/100BT Ethernet, Gigabit
Ethernet, E1/DS1 and E3/DS3 ports:
•
Facility - the received signal is looped back towards the transmitter port
immediately on entering the interface port. AIS is inserted in the signal
towards the cross-connect on the 2x155/622M aggregate circuit pack.
•
Terminal - the signal is looped back towards the cross-connect on the
2x155/622M aggregate circuit pack just before reaching the interface
transmitter.
provides an overview of terminal and facility loopbacks.
Figure 6-1
Facility and terminal loopbacks
summarizes the supported loopback types for the
different ports and the appropriate AIS alarm conditioning.
