SmartAX MA5616 Multi-service Access Module
Configuration Guide
l
The MoIP service supports two transmission modes: the transparent transmission mode and the
relay (redundancy) mode. The MA5616 supports only the modem service in the transparent
transmission mode. In the transparent transmission mode, the MG uses the G.711 mode to encode
and decode the modem signal, and processes the signal like processing the common RTP data.
The transparent transmission mode depends on the bearer network to a great extent.

Step 2 Configure the transmission mode of the modem.
Run the modem parameters tranmode command to configure the transmission mode of the
modem. Currently, only the modem service in the transparent transmission mode is supported.
Step 3 Check whether the modem parameters are the same as those in the data plan.
Run the display fax-modem parameters and display modem parameters commands to query
modem parameters.

To configure the MA5616, do as follows:
Issue 04 (2011-10-30)
This reduces delay, improves the performance of transparent transmission, and decreases
the impact of packet loss on the transmission of the modem service data.
RFC 2198 function: Through the redundant transmission, the RFC 2198 improves the
reliability of data transmission. When the network packet loss occurs, the RFC 2198 can
ensure the service quality.
Run the interface sip command to enter the SIP interface mode.
Run the fax-modem parameters negomode command to configure the negotiation mode.
(Optional) Run the fax-modem parameters packet-interval-10ms to enable or disable
the 10 ms packing function.
(Optional) Run the command to configure the RFC 2198 function.
(Optional) Run the command to configure the startup mode of the RFC 2198 function.
(Optional) Run the fax-modem parameters vbd-codec command to configure the codec
mode of the voice-band data (VBD).
(Optional) Run the fax-modem parameters vbd-pt-type command to configure the
payload type of the VBD.
(Optional) Run the rfc2833 set rfc2833-fax-modem command to configure the mode for
reporting fax or modem events.
The negotiation mode of the MA5616 is self-switch.
The 10 ms packing function and the RFC2198 intelligent startup function are enabled.
The RFC2198 negotiation mode is fixedstart.
The codec mode of the VBD is G.711A.
The payload type of the VBD is static payload.
The transmission mode of the modem is transparent transmission (thoroughly).
