Fiber Link Administration

Issue 7 November 2003
All Installations
1. When the system reset is finished, type status port-network 2 and press
Enter
. The Port Network Status screen appears. Verify that PNC Active is
“up” and that the Service State is “in.”
2. A Span LED, on the front of the DS1 Converter circuit pack, must be on for
each active facility administered. For example, if Facility A and Facility B
are administered, then the top 2 Span LEDs on the circuit pack must be on
(yellow). The yellow LEDs are on only if no problems were encountered
during the administration of hardware. Span LEDs associated with
non-administered facilities (C and D, in this example) should be off.
3. Perform a test call, if desired.
Administer Fiber Links on Duplex Systems
All non-duplicated Switch Node Interfaces to Switch Node Interface fiber links are
automatically duplicated. When PNC Duplication is enabled on the
System-Parameters Customer-Options form, the following administration forms
change:
■
Cabinet Form
—
Additional fields appear to allow administration of switch
nodes to A-PNC and B-PNC sides of the CSS. The B-PNC is the
duplicated hardware for the A-PNC. Either the A-PNC or the B-PNC can
provide full customized service. B-PNC cannot be used in a simplex PNC
configuration. Pairing of switch nodes is also defined here.
■
Fiber Link Administration Form
—
Additional fields appear to allow
administration of fiber links on the B-PNC side of the CSS. If an endpoint
on the A-PNC side is administered as an SNI, its corresponding endpoint
on the B-PNC side is determined (if switch nodes are paired in the cabinet
form prior to this administration) and displayed. However, administration of
the duplicate B-PNC link is not enforced until duplication is in full operation.
■
Duplication-Related System-Parameters Form
—
An additional field
appears to enable operation of PNC duplication.
1. Type change system-parameters customer-options and press
Enter
. On
Page 2 of the form, set the
PNC Duplication?
field to y. Press
Enter
.
2. Type change system-parameters duplication and press
Enter
. Change
the
Enable operation of PNC duplication?
field to y. Press
Enter
.
3. Type status pnc and press
Enter
. Verify the
Duplicated?
field is yes.
4. Type list fiber and press
Enter
. All administered fiber connections display.
5. If a previously used fiber link is to be reused, type add fiber <number>
and press
Enter
. If this is a new fiber link, type add fiber next and press
Enter
.
