6. Verify that no LEDs or alarms are activated. If any LEDs or alarms
are activated, refer to Trouble Clearing: IXL-001.
7.
NOTE:
Ring releases support only manual VT1.5 and STS-1
cross-connections. Manual STS-1 and/or DS1
cross-connections have to be made at each shelf to
configure the transmission path for each DS3/DS1 circuit
being established. Either terminating (drop)
cross-connections or "drop and continue" cross-connections
are made at terminating nodes and pass-through
cross-connections are made at intermediate nodes.
NOTE:
The following commands may be used to convert, delete,
enter, and retrieve STS-1 cross-connections:
dlt-crs-sts1, ent-crs-sts1, and rtrv-crs-sts1.
See the Commands and Reports section of this manual for a
description of commands. See Cross-Connection
Provisioning in the Administration and Provisioning section
of this manual for more information on cross-connection
provisioning.
Determine the necessary STS-1 cross-connections for each node
from the work order or circuit order.
8. Make necessary STS-1 cross-connections for each node in the
network.
9.
NOTE:
For a DS3 circuit in a path protected ring network, the
sw-path-sts1:address command must be used at the
terminating nodes [and dual ring interworking (DRI) nodes in
a DRI ring network] to switch the active STS-1 (DS3) path to
repeat this test on the other path.
Perform DS3-to-DS1 transmission test for each circuit being put
into service (optional).
10. Use the set-t3: command to set the characteristics of the DS3
port.
