Chapter 11 Worked Configuration Examples
11.2 M2PA Longhaul Configuration
The following is an example of a Signaling Gateway offering the longhaul of SS7 signaling over M2PA. The
Signaling Gateway is connected to a Signaling End Point (SEP) on the TDM side and an SEP on the IP side.
Each SEP treats the Signaling Gateway as an STP to reach its destination SEP. On the TDM side, board 1 is
used to terminate two SS7 E1 PCMs with clock being taken from SEP 1. Each PCM carries 1 timeslot with SS7
signaling to SEP 1. On the SIGTRAN IP side, two M2PA associations are used to convey two SS7 signaling
links to SEP 2. The Point Code of the gateway equipment is 3; the SEPs are Point Codes 1 and 2 respectively.
Note: Potentially, routing keys are not required in this scenario, in that you could simply configure a the
incoming route to go directly to the TDM destination. Routing keys are present since they allow
the Signaling Gateway to validate the DPC in the received data message.
