B.3.7 Transponder/Muxponder Port Service State Transitions
Table B-10 ONS 15454 Transponder/Muxponder Port Service State Transitions (continued)
Current Service State
OOS-MA,MT (ANSI)
Locked-enabled,maintenance (ETSI)
1. The transponder and muxponder cards have both client and trunk ports. To bring up service, it is not necessary for both the client side and trunk side to
be in the IS-NR (ANSI)/Unlocked-enabled (ETSI) service state.
2. In a client-side facility loopback, the client port is in the OOS-MA,LPBK & MT (ANSI)/Locked-enabled,loopback and maintenance (ETSI) service state
and the remaining client and trunk ports can be in any other service state. In a client-side terminal loopback on transponder cards, the client port is in
the OOS-MA,LPBK & MT service state and the trunk ports are in IS-NR (ANSI)/Unlocked-enabled (ETSI). For client-side terminal loopbacks on
muxponder cards, the client port is in the OOS-MA,LPBK & MT service state and the remaining client and trunk ports can be in any service state.
3. In a trunk-side facility loopback, the trunk port is in the OOS-MA,LPBK & MT (ANSI)/Locked-enabled,loopback and maintenance (ETSI) service state
and the remaining client and trunk ports can be in any other service state. In a trunk-side terminal loopback, the trunk port is in the OOS-MA,LPBK &
MT (ANSI)/Locked-enabled,loopback and maintenance (ETSI) service state and the client ports are in IS-NR (ANSI)/Unlocked-enabled (ETSI) for
complete loopback functionality. This type of loopback affects all client ports because it is performed on the aggregate signal.
