SmartAX MA5616 Multi-service Access Module
Configuration Guide
Prerequisites
According to the actual network, a route from the MA5616 to the MGC must be configured to
ensure that the MA5616 communicates with the MGC normally.

Precaution
The media gateway control protocol (MGCP) is a master/slave protocol. under which the MGC
controls the AG to implement call connection and disconnection. The data on the AG for the
interconnection with the MGC, such as the attributes of the MG interface and the attributes of
the VoIP user, must be the same as the corresponding data on the MGC. Therefore, before
configuring the VoIP service, you must contact MGC engineers to check and ensure that the
interconnection data plan for the AG is consistent with the corresponding plan for the MGC.

The voice over IP (VoIP) service uses the IP packet switched network for transmission
after the traditional analog voice signals are compressed and packetized. This service lowers
the cost of the voice service. For the detailed description of the VoIP service, see Voice
Feature in the Feature Description.
Defined by the International Telegraph and Telephone Consultative Committee (CCITT),
the ISDN is a communication network evolved from the Integrated Digital Network (IDN).
The ISDN service provides the E2E digital connection and supports multiple types of voice
and non-voice telecom services. On the ISDN network, users can access the network
through the following two interfaces: (The ISDN technology provides two types of user-
network interfaces based on the user-network interface reference model.)
– ISDN basic rate interface (BRI), which supports a rate of 144 kbit/s and provides two
B channels (for carrying services) and one D channel (for transmitting call control
signaling and maintenance and management signaling). The rate of B channels is 64
kbit/s and the rate of D channel is 16 kbit/s. The service carried on the ISDN BRI is the
ISDN basic rate access (BRA) service.
– ISDN primary rate interface (PRI), which supports a rate of 2.048 Mbit/s and provides
30 B channels and one D channel. The rates of the B channel and D channel are both
64 kbit/s. The service carried on the ISDN PRI is the ISDN primary rate access (PRA)
service.
The MA5616 supports only the VoIP ISDN BRA service.
The MA5616 provides the ISDN BRA service through the DSL port on the DSLD board.
For detailed description of the DSLD board, see DSLD - Eight-Channel ISDN Service
Board in the Hardware Description.
provides the data plan for configuring the H.248-based VoIP ISDN BRA service.
