Message What To Do What It Indicates
64KCC Loop OOF,
Slot
ss Port p
An Out of Frame (OOF)
condition has been detected
for the identified OCU-DP
interface. 1. Check the that DSU is
configured for the correct
speed.
2. Check the cable to ensure
that the pairs are not
crossed.
DDS Net Failure, Slot
ss Port p, cccccc The identified OCU-DP
interface is receiving a DDS
network code of
cccccc from
the network. This is a 6-bit
code representing bits 2–7 of
the DS0 code defined in AT&T
PUB 62310. The least
significant bit is to the left.
Contact the DDS service
provider.
Loss of Loop Timing,
Slot
ss Port p, cccccc
The identified OCU-DP
interface cannot recover
timing from the received signal
on the local loop. This typically
occurs when the CPE
CSU/DSU is misconfigured for
the wrong rate (e.g., 19.2
kbps) when the OCU-DP is
configured for 56K or
Switched 56 operation. Check that the CPE CSU/DSU
rate matches the OCU-DP
rate.
Primary Clock Failed A failure of the primary clock
source configured for the NAM
is detected and the secondary
clock is providing the timing
for the NAM. This condition
clears when the configured
primary clock is restored. 1. If the primary clock was
derived from the network,
contact the network
provider.
2. Check the clock source
connector.
Secondary Clock
Failed A failure of the secondary
clock source configured for the
NAM is detected and the
internal clock is providing the
timing for the NAM. The clock
source will not automatically
switch from internal until the
primary clock source returns. 1. If the secondary clock was
derived from the network,
contact the network
provider.
2. Check the clock source
connector.
Network Com Link
Down The network communication
link is down for the COM port.
This condition occurs only
when the COM port is
configured for Net Link and
communications between the
management system and the
T1 access unit is not currently
possible for the port. 1. Check that the Port Use
configuration option is
properly set (see the
Technical Reference for
configuration option
information).
2. Check cables.
