SMG digital gateway
A correspondence between SS and Caller ID categories can be adjusted for the gateway. For
configuration, see section
4.1.8.1
SS Category

4.1.7.2.1
Examples
An example of SMG connection for operation in the SS-7 quasi-associated mode via signalling transfer
points (STP).
Objective
A connection is required between SMG and the opposite signalling point (SP) using two signal links. The
first signal link should pass through STP 1 signalling transition point, while the second one—through STP 2.
Point code: SMG4 = 22, STP 1 = 155, STP 2 = 166, SP = 23.
Solution
In addition to basic settings, set Own Point C
ode (OPC)
=
22
and
ISUP Opposite Code (DPC-ISUP)
=
23
in the
SS-7 Line Groups
menu.
Let us assume that stream 0 is connected to STP 1, while stream 1—to STP 2. 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; select the pre-created SS-7 line group in
SS-7 Line Group
settings and set
MTP3
Opposite Code (DPC-MTP3)
to
155
for stream 0 and to
166
for stream 1.
An example of SMG connection for operation in the SS-7 quasi-associated mode via PBX with STP features.
LS— an SS-7 line group (Link Set).
Objective
A connection is required between SMG and two PBXs with STP features (PBX/STP); when the 1LS main
circuit group between SMG and PBX/STP 1 fails, signalling messages should be sent via 2LS.
