Cisco ONS 15454 Procedure Guide, R5.0
August 2005
Chapter 6 Create Circuits and VT Tunnels
NTP-A147 Create a G-Series STS Circuit
Step 8
Define the circuit attributes:
•
Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•
Size—Choose the circuit size. Valid circuit sizes for a G-Series circuit are STS-1, STS-3c, STS6c,
STS-9c, STS-12c, STS-24c, and STS-48c.
Note
Restrictions apply to provisioning multiple circuits on a G-Series card when one of the
circuit sizes provisioned is STS-24c. Refer to the
Cisco ONS 15454 Reference Manual
for
complete information.
•
Bidirectional—Leave the default unchanged (checked).
•
Create cross-connects only (TL1-like)—Uncheck this box.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
–
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
•
Apply to drop ports—Leave this box at the default (unchecked).
Note
Loss of signal alarms are generated if ports in the IS-NR service state are not receiving
signals.
•
Auto-ranged—Unavailable.
•
Protected Drops—Leave the default unchanged (unchecked).
Step 9
If the circuit will be routed on a path protection, complete the
“DLP-A218 Provision Path Protection
.
Note
For circuits routed on path protection, check
Switch on PDI-P
if you desire to override the
G-Series Ethernet Link Integrity feature. Switch on PDI-P configures the card to switch traffic
when an STS payload defect indicator (PDI-P) is received. Under Ethernet Link Integrity, the
PDI-P indication normally triggers a bidirectional failure. Overriding the Ethernet Link Integrity
feature might be desired for applications utilizing dual Gigabit Ethernet feeds from a customer's
location or drop and continue paths.
