SMG digital gateway 65
Let us assume that stream 0 of SMG is connected to PBX/STP 1 and is configured to use the first SS-7 line
group, while stream 1 is connected to PBX/STP 2 and is configured to use the second SS-7 line group. Specify the
following in the stream settings: SS7 Signalling protocol; configure CIC numbering correctly and select the
required E1 stream time slot for signalling D-channel; specify the second SS-7 line group in Redundant SS-7 Line
Group in configuration of the first SS-7 line group.
An example of SMG connection for operation in the combined mode.
Objective
Only voice channels are used for communication between SMG and PBX/SP; signalling traffic should be
transferred via PBX/STP 1 and PBX/STP 2.
Solution
Let us assume that stream 0 of SMG is connected to PBX/STP 1 and is configured to use the first SS-7 line
group, while stream 1 is connected to PBX/STP 2 and is configured to use the second SS-7 line group; stream 2 of
SMG is connected to PBX/SP and is configured to use the third SS-7 line group. Specify the following in the
stream settings: SS7 Signalling protocol; configure CIC numbering correctly and select the required E1 stream
time slot for signalling D-channel of streams 0 and 1; specify the first SS-7 line group in Primary SS-7 Line Group
in configuration of the third SS-7 line group; specify the second SS-7 line group in Secondary SS-7 Line Group in
configuration of the third SS-7 line group.

4.1.7.3.1 Configuration
This section describes configuration of general parameters for SIP stack, custom settings for each direction
operating via SIP/SIP-Т/SIP-I protocols, and SIP subscriber profiles.
SIP (Session Initiation Protocol) is a signalling protocol, which used in IP telephony. It facilitates basic call
management tasks such as session start and termination.
SIP network addressing is based on the SIP URI scheme:
