9124-A2-GH30-00 June 1999 - Preliminary
Table 11-1. Alarm Conditions (5 of 6)
Alarm Condition What To Do What It Indicates
OOF at Network 1 An Out of Frame (OOF)
condition has been
detected on the interface.
An OOF condition is
declared when two out of
four frame-synchronization
bits are in error.
This condition clears when
a reframe occurs.
For the network or DSX-1
interface:
1. Check that the cable is
securely attached at both
ends.
2. Check that the framing format
for the interface is correct.
3. Contact your network provider.
OOF at ISDN PRI
(Active/Idle) For an ISDN PRI DBM
interface, Active indicates
that a backup call was in
progress when the ISDN
network failure was
detected, and Idle indicates
that the call was in idle
mode when it was
detected.
It could indicate a cabling
problem, incompatiblity
between the ISDN network
and the unit, or an ISDN
network problem.
For an ISDN PRI DBM interface,
contact your ISDN network
provider instead of your T1
network provider.
Power Supply Alarm Output voltage for the 5-slot
housing has dropped below
the system’s tolerance
level. 1. Check that the power cord is
securely attached at both
ends.
2. Check that the power outlet
has power by plugging in
equipment that that you know
is operational, then check the
circuit breaker.
3. Replace the power supply.
Primary Clock Failed A failure of the configured
primary clock source for the
unit was detected and the
secondary clock is
providing the timing for the
unit.
This condition clears when
the configured primary
clock is restored.
1. Check that the network cable
is securely attached at both
ends.
2. Contact your network provider.
Primary & Secondary
Clocks Failed A failure of both clock
sources configured for the
unit was detected
This condition only applies
to T1 network and DSX-1
interfaces. It clears when
the configured primary
clock is restored.
1. Check that the network cable
is securely attached at both
ends.
2. Contact your network provider.
