11.1Backhaul Configuration

The following is an example of a Signaling Gateway working in a “backhaul” configuration. The Signaling Gateway is connected to a single Signaling End Point (SEP) on the TDM side. On the IP side there is a single Application Server (AS) that processes circuit-related messages. The AS exists on two ASPs for resilience. On the SS7 side, boards 2 and 3 are used to terminate two SS7 E1 PCMs. Each PCM carries 1 timeslot with SS7 signaling. The Point Code of the gateway equipment is 1, which is the same as that of the application server.

11.2M2PA Longhaul Configuration

The following is an example of a Signaling Gateway offering the longhaul of SS7 signalling 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.
