– IS—Puts the circuit cross-connects in the IS-NR service state.
– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is
not passed on the circuit.
– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses
alarms and conditions. When the connections receive a valid signal, the service state
automatically changes to IS-NR.
– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance
state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks
to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms
temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is
complete. See the “DLP-A230 Change a Circuit Service State” task on page 19-19.
Note A VAP automatically transitions into the IS service state after a VT circuit is created.
For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter
in the Cisco ONS 15454 Reference Manual.

Step 9 In the Circuit Source area, choose the source node, slot, port, and STS for the VAP. The VAP source is
where the DS-1 (VT1.5) circuits will be aggregated into a single STS. The VAP destination is where the
DS-1 circuits originate.
a. From the Node drop-down list, choose the node where the VAP will originate.
b. From the Slot drop-down list, choose the slot containing the OC-N, EC1, DS3, DS3E, DS3i-N-12,
DS3XM-6, or DS3XM-12 card where the VAP will originate.
c. Choose either the port or STS:
• If you choose an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, or DS3XM-12 card from the Port
drop-down list, choose the source port.
• If you choose an OC-N card, from the STS drop-down list, choose the source STS.
