The report mode of the modem event:
l
Direct: In direct mode, the host reports the modem event to the MGC immediately when
the host receives a modem event.
l
Delay: In delay mode, the host does not report the modem event immediately after an event
is received, but waits for a period of time until the event times out and the fax signal is
detected. In this way, when the high-speed modem machine fails in the high-speed
transmission negotiation, it can transmit data in low-speed transmission mode.
l
Direct for high-speed signals: In the mode of the direct for high-speed signals, the host
reports the modem event with low speed signals to the MGC 5.5s after the host receives a
modem event; the host reports the modem event with high speed signals to the MGC
immediately when the host receives a modem event.
Procedure
Step 1
Configure public fax and modem parameters.
1.
Run the
fax-modem parameters negomode
command to configure the negotiation mode.
2.
(Optional) Run the
fax-modem parameters packet-interval-10
command to enable or
disable the 10 ms packing function.
3.
(Optional) Run the
fax-modem parameters RFC2198-start-mode
command to configure
the RFC2198 function.
4.
(Optional) Run the
fax-modem parameters transevent
command to configure the
transmission mode of the modem event.
5.
(Optional) Run the
fax-modem parameters vbd-codec
command to configure the codec
mode of the voice-band data (VBD).
6.
(Optional) Run the
fax-modem parameters vbd-pt-type
command to configure the
payload type of the VBD.
Step 2
Configure the event report mode of fax codec.
1.
Run the
modem parameters tranmode
command to configure the transmission mode of
the modem.
2.
(Optional) Run the
modem parameters eventmode
command to configure the report mode
of the modem event.
NOTE
l
To enable the MGC to quickly respond to a modem event, you need to configure the report mode
of the modem event as the direct report mode.
l
By default, the transmission mode of the modem is the transparent transmission mode, and the
modem event is reported in the direct mode.
Step 3
Query public fax and modem parameters and the codec mode of the fax.
Run the
display fax-modem parameters
and
display modem parameters
commands to query
modem parameters.

Example
Assume that:
l
The negotiation mode of the MA5616 is self-switch.
