NTP-A185 Create a Manually Routed DS-3 Circuit
–
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
For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter
in the
Cisco ONS 15454 Reference Manual
.
•
Apply to drop ports—Check this check box if you want to apply the administrative state chosen in
the State field to the circuit source and destination ports. CTC applies the administrative state to the
ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is
larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog
box displays the ports where the administrative state could not be applied. If the check box is
unchecked, CTC does not apply the administrative state of the source and destination ports.
Note
Loss of signal alarms are generated if ports in the IS-NR service state are not receiving
signals.
•
Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is,
to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check
box, CTC provides only protected cards as source and destination choices.
Step 8
If the circuit will be routed on a path protection, complete the
“DLP-A218 Provision Path Protection
.
Step 9
Click
Next
.
Step 10
Complete the
“DLP-A510 Provision a DS-3 Circuit Source and Destination” task on page 22-3
Step 11
In the Circuit Routing Preferences area (
Route Automatically
. When
Route Automatically is not selected, the Using Required Nodes/Spans, Review Route Before Circuit
Creation, and VT-DS3 Mapped Conversion check boxes are unavailable.
Step 12
To set the circuit path protection, complete one of the following:
•
To route the circuit on a protected path, leave
Fully Protected Path
checked and continue with
. Fully protected paths might or might not have path protection path segments (with primary
and alternate paths), and the path diversity options apply only to path protection path segments, if
any exist.
•
To create an unprotected circuit, uncheck
Fully Protected Path
and continue with
•
To route the circuit on a BLSR protection channel, if available, uncheck
Fully Protected Path
,
check
Protection Channel Access
, click
Yes
in the Warning dialog box, then continue with
.
Caution
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
switches.
Step 13
If you selected Fully Protected Path in
and the circuit will be routed on a path protection, choose
one of the following:
•
Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection
portions of the complete circuit path are nodally diverse.
•
Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not
possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
