51 CLOCK PROBLEM
Clock synchronization prob-
lem detected on an add-on
module interface
Board location.
Access marker
INFO 0 = type of interface: T0, T2,
DASS2, etc.
Check there
is no syn-
chronizing ac-
cess in the
add-on mod-
ules
52 SPECIFIC ACCESS PROB-
LEM DETECTED BY AN
ISDN BOARD LEVEL 2
Board location.
Access marker
INFO 0 =1: FCS (Frame Check Se-
quence) 2: CRC (Cyclic Redundancy
Check)
If the fault re-
curs fre-
quently,
check the
connection to
the public net-
work.
53 ALARM DETECTED ON A
PRIMARY ACCESS
Board location.
Access marker
INFO 0 = XX : type of alarm
- 00 : Level 1 synchronized; all sys-
tems go.
- 01 : Synchronization loss in "mul-
tiple frame" mode (synchronization
in "double-frame" mode is correct).
- 02 : No multiple frames; T2 auto-
matically starts "double-frame"
mode.
- 03 : RDS (...)
- 04 : Remote Frame Alarm.
- 05 : Synchronization loss in
"double-frame" mode.
- 06 : Alarm Indication Signal; se-
quence of "1's received, interface
not synchronized.
- 07 : Loss of Frame Alignment
(occurs when the cable is discon-
nected).
- 08 : Temporary clock lag; syn-
chronization established.
- 09 : Error rate; number of error
frames > 5 in 1 second.
- 10 : Erroneous frames received in
the checksum (CRC).
- 11 : The network emits this alarm
when the FALC sends erroneous
frames in the CRC.
Ensure that
the alarm dis-
appears.
If the fault re-
curs fre-
quently,
check the
connection to
the public net-
work.
