APS Configuration Problems
APS Configuration Problems
The following sections describe possible APS configuration problems.
Not Able to Correctly Set Up APS 1+1 Line Redundancy Configuration
Description:
The
addapsln
user interface command fails to execute correctly for APS 1+1 line addition.
Initial Investigation:
The
addapsln
command is used to set up the APS line redundancy configuration.
For APS 1+1 configurations, BPX software supporting APS and BXM firmware supporting APS must
be used.
The following hardware requirements must be met:
•
BXM-Enhanced OC-3 or OC-12 front cards. BXM-155-4 or BXM-155-8 front card of revision C or
higher. BXM-622-2 or BXM-622-1 of revision E or higher.
•
RDNT-BP daughter backplane—special APS redundancy backplane
•
BXM OC-3 or OC-12 APS back cards (they have two connectors on the back instead of one and
require the daughter backplane in order to fit into the BPX backframe.
•
Card redundancy (
addcdred
or
addyred
) must be set up on the card pair prior to
addapsln
, see
section on Y-cable issues. APS does not use the special Y-cable, it uses straight cables on both ports
to the remote port. The redundant card must be in adjacent slots.
•
Using a back card frame containing internal card cage stiffeners requires that only slots 2–5 and
10–13 be used for APS 1+1 configurations. This is due to the stiffeners preventing the daughter
backplane from fitting into the back card frame.
•
A newer back card frame removes the slot restriction of having to put daughter backplane and APS
back cards in slots 2 to 5 and 10 to 13.
Unable to Set Up APS 1:1 Line Redundancy Configuration
Description:
The
addapsln
user interface command fails to execute correctly for APS 1:1 line addition.
Initial Investigation:
For APS 1:1 configuration, two adjacent lines on the same card are used. No
special hardware is required; however, the maximum connections supported must be reduced by half
using the
cnfcdaps
command. FW and SW support of APS is required.
Workaround:
APS 1:1 can be run on non-APS-enhanced BXM card by halving the number of channels
the card can support (
cnfcdaps
). No special back cards are needed for APS 1:1.
For APS 1:1 configuration the APS line must be configured (
addapsln
) before a line (
upln
) or trunk
(
uptrk
) can be upped. Conversely, the line or trunk must be downed before the APS line can be deleted
(
delapsln
).
Use
dspapsln
to verify that the APS line has been added.
