b. This error indicates that the DS1 facility has been busied out via the
busyout ds1-facility
command. To resolve this error, release the DS1
facility via the
release ds1-facility
command.
c. A minor failure occurred on the DS1 interface hardware on the DS1 CONV
circuit pack associated with this DS1 facility. Replace the DS1 CONV
circuit pack.
d. DS1 CONV circuit packs in this DS1 CONV Complex do not match in their
framing formats or line coding formats.
Aux Data 1
indicates that the framing formats (ESF or D4) do not match.
For TN574 DS1 CONV boards, the framing mode is administered on the
fiber-link form. The TN1654 DS1 CONV has option switches located on the
component side of the circuit pack. If T1 operation is selected via the first
switch, four additional switches are used to select the framing mode for
each facility. The Framing Mode field on the fiber-link form is display-only
for the TN1654 boards. It displays what the switch is set to for the DS1
facility. It can not be administered.
Aux Data 2
indicates that the line coding formats do not match. Line
Coding is an administrable value on the fiber-link form. The line coding
options are
ami-zcs
or
b8zs
for TN574 boards and TN1654 boards in T1
mode. For TN1654 boards in E1 mode, the line coding options are
ami-basic
or
hdb3
.
This error should clear in 15 minutes.
1. Verify that DS1 facility and the network is using the same line
coding (ami-zcs, b8zs, ami-basic, hdb3) and framing mode (ESF,
D4). Use
list fibers
and
display fiber
-link commands to check the
values for this DS1 facility. Contact T1 Network Service to check the
modes used by the network.
If the framing mode format differs on boards in a TN1654 DS1
CONV Complex, the DS1 CONV board that has its option switch set
incorrectly will have to be physically removed from the system in
order to set the facility framing mode switch properly.
2. If the problem persists, reset both DS1 CONV circuit packs via the
reset board
command.
3. If the problem still persists, replace this DS1 CONV circuit pack.
4. If the problem still persists, replace the DS1 CONV circuit pack at
the other end of the DS1 CONV Complex.
e. More than 88 negative and/or positive slip errors occurred. This error will
clear when there are no slips for 1 hour.
1. Enter display errors and follow the associated repair procedures
for any SYNC, TDM-CLK, and SNC-BD errors.
2. Verify that the DS1 facility and the network are using the same Line
Coding. For TN574 boards and TN1654 boards in T1 mode, also
verify that the Framing Mode used is the same. Use list fibers and
