7.6 Configuring the MoIP Service (Based on the H.248
Protocol)
This topic describes how to configure the MoIP service when the H.248 protocol is used to
transmit the modem data service over the IP network.
Prerequisites
l
The communication between the MG and the MGC must be in the normal state.
l
The voice service port used by the MoIP service and the voice service on that port must be
in the normal state.
Context
The MA5616 supports the self-switch mode and the auto-negotiation mode:
l
Self-switch: If the self-switch mode is configured, the modem working mode of the
MA5616 is not controlled by the MGC. Therefore, manual configuration is required.
l
Auto-negotiation: If the auto-negotiation mode is configured, the modem working mode
of the MA5616 is automatically configured during the negotiation with the MGC.
Therefore, manual configuration is not required.
The MA5616 supports the 10 ms packing function and the RFC 2198 function.
l
10 ms packing function: In addition to the 20 ms G.711 transparent transmission, the modem
transparent transmission function is added with the 10 ms G.711 transparent transmission.
This reduces delay, improves the performance of transparent transmission, and decreases
the impact of packet loss on the transmission of the modem service data.
l
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.
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.
