Reset all configuration options from one of the
factory-loaded option sets: FacC, FacT, FacB,
MPTC, or MPTT. Refer to Table 2-1.
nn.n DDS
Indicates the data rate (
nn.n) of the active core
(DSU or DBM) when there are no alarms.
Data rate set by configuration option
Rate(Kbps) or detected by autorating.
DDS F:
alarm
Digital facility alarm;
alarm is one of the
following network alarms:
1. BiplrViol – Excessive Bipolar Violations.
Data rates do not match or network trouble.
2. CrossPairs – Crossed Pairs. DDS Receive
and Transmit pairs are crossed.
3. CMI Fac Alarm – Control mode idle
notification from a remote unit.
4. No Signal – No signal received. Local DSU
network problem.
5. No Sync – No synchronization. Rate(Kbps)
is set to Auto and the DSU is attempting to
detect the data rate.
6. OutofServc – Out-of-Service condition.
Rate(Kbps) is set to 56 kbps or less and
remote not detected.
7. Rate Confl – Rate conflict. Rate(Kbps) is set
to Auto and the total of the port speeds
exceeds the aggregate rate.
1. Verify that the DSU Rate(Kbps) setting
matches the network speed. Try temporarily
setting the Rate(Kbps) to Auto and the
network speed will appear on the H/S
display if the rate can be determined. If the
network is the problem, contact the service
provider.
2. Check the local wiring.
3. The CMI notification is set using the Backup
configuration option FAOnCMI.
4. Check DDS line from rear of DSU and from
wall for network connection. Contact the
service provider.
5. Set the Rate(Kbps) configuration option to
the actual data rate. If bipolar violations
occur, contact the service provider.
6. Verify that the remote site is in service.
7. The total of port speeds exceeds the data
rate. Lower the PrtSp(Kbps).
Dial Tone:Fail
Dial tone test was enabled and test failed.
Try another piece of equipment on the line. Line
may be out of order.
DSU:Device Fail
Internal failure in the DSU is detected.
Initiate a Device self-test (Devic) from the Test
branch. If message continues, call your sales or
service representative.
DSU:Disable
DSU transmitter is disabled.
To enable the DSU, use Control branch’s
control option TxCtl.
