Device Health and Status Messages
Message ActionCondition
MUX CommunicFail No reply from TDM circuit card. The DSU
periodically polls the TDM circuit card for health
and status. When the DSU does not receive a
response, this message appears.
The problem could be temporary while
retraining is in progress. If message continues,
initiate a Device self-test (Devic) from the Test
branch. If failure continues, call your sales or
service representative.
MUX Device Fail Internal failure of TDM or MCMP is detected. Initiate a Device self-test (Devic) from the Test
branch. If failure continues, call your sales or
service representative.

NetI Network Interface speed when configuration
option NetIntf is set to Forc.
Informational message.
NetI F:No Signal No signal from Network Interface alternate port. The configuration option NetIntf is set to Forc
for aggregate switching.
OutofFrameThresh For DSUs operating on a single port (rate
adaption or nondisruptive), TDM, or MCMP
, the
local DSU has detected a continuous MUX
Out-of-Frame condition.
If the alarm continues on a point-to-point circuit
and the local DSU is configured for automatic
backup, the local DSU disruptively tests the
DDS circuit. If the test fails, the DSU issues a
DDS Facility alarm and initiates dial backup.
The alarm clears when a local DSU
synchronizes with a remote DSU. Both DSUs
need to have the same port speeds.

.
test
is one of the following tests:
BERT — Bit Error Rate Test
DL — Digital Loopback
DT — Digital Test
DTE — DTE Loopback
RL — Remote Digital Loopback
init
is one of the following initiators:
DCP — Diagnostic Control Panel
(front panel)
DTE — Data T
erminal Equipment
LPDA — NetView-initiated test
NMS — Network Management System
Remt — Remote DSU
TM — Test Mode
Refer to the
Test Branch

for details regarding each test. Many tests
require no action.
