ed.2 Trouble shooting 69
##758 (trans) T5 time out (60 seconds) has occurred. Or, the number of times the
protocol signal has been sent has exceeded the limit in ECM transmission after
transmitting PPS-MPS.
Main cause Action
■
The page buffer of the other machine is full
or busy. The RNR cannot be received cor-
rectly, after transmitting PPS-MPS, and the
appropriate signal cannot be received cor-
rectly after transmitting RR.
■
Increase the T5 timer setting, to avoid an er-
ror.
■
Change the ECM frame size: from 256 bytes
to 64K bytes.
##759 (recep) The number of times the protocol signal has been transmitted has
exceeded the limit. Without receiving the appropriate signal, after transmitting
PPS-MPS in ECM transmission.
Main cause Action
■
The line condition is poor. PPS-MPS has
been transmitted, PPR has been received
four times, CTC has been transmitted. But,
the other machine cannot receive it correct-
ly.
■
The line condition is poor. PPS-MPS has
been transmitted, PPR has been received
four times, CTC has been transmitted. But,
the other machine cannot receive the appro-
priate signal.
■
Increase the level of transmission, using pa-
rameter 07 of #2 MENU. Permitting correct
receipt of the CTC signal.
■
Ask the other party to increase the level of
transmission, permitting correct receipt of
the signals.
##760 (trans) The appropriate signal could not be received, after transmitting
PPS-EOM during ECM transmission. And, the number of times that the protocol
signal was transmitted exceeded the limit.
Main cause Action
■
The line condition is poor. Preventing trans-
mission of PPS-MPS.
■
The line condition is poor. Preventing cor-
rect reception of signals.
■
Increase the level of transmission. Permit-
ting correct receipt of the PPS-MPS signal.
■
Adjust the NL equaliser. Permitting correct
receipt of the PPS-MPS signal.
■
Attach EPT to the V29 modem signal.
■
Ask the other party to increase the level of
transmission, permitting correct receipt of
the signals.
