Bad frame Acc P1 (S=0xP2) ABT=P3 TOT=0xP4P5 Nok=0xP6P7

Acc: HDLC Access number
S : Status register value.
ABT: ratio (%): nb aborted frames/total nb bad frames (current sample)
TOT: Size of the current sample ; sum of all frames : good+aborted+bad CRC
Nok: nb bad received frames : aborted+bad CRC (current sample).
Bad HDLC frames are received by an ISDN coupler. These bad frames consist
either in aborted frames or in frames wich a bad CRC.
The cause of this error is either a real problem with a harware
component or a synchronisation problem (synchro slip). The given
counters will be reseted every 10000 received frames. In case of a line with
noise, most errors will be CRC errors : the ABT value should be near zero.
The Nok/TOT ratio give an idea of the loss of quality of service.
no reaction of the system
On a PRA2 or BPRA2 coupler, don't forget to verify that the T2
straps are well set in the symetrical mode!
Verify the synchro configuration ; try with another board if
possible ; else signal the problem."


Check synchronization in your PBX. ("infocs" command)
