##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
The page buffer of the other machine is full
I
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.
##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
The line condition is poor. PPS-MPS has
I
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

the other machine cannot receive the appro-
priate signal.
##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
The line condition is poor. Preventing trans-
I
mission of PPS-MPS.
The line condition is poor. Preventing cor-
I
rect reception of signals.

Action
Increase the T5 timer setting, to avoid an er-
I
ror.
Change the ECM frame size: from 256 bytes
I
to 64K bytes.
Action
Increase the level of transmission, using pa-
I
rameter 07 of #2 MENU. Permitting correct
receipt of the CTC signal.
Ask the other party to increase the level of
I
transmission, permitting correct receipt of
the signals.
Action
Increase the level of transmission. Permit-
I
ting correct receipt of the PPS-MPS signal.
Adjust the NL equaliser. Permitting correct
I
receipt of the PPS-MPS signal.
Attach EPT to the V29 modem signal.
I
Ask the other party to increase the level of
I
transmission, permitting correct receipt of
the signals.
