Cisco voice AS5350 SS7 route traffic to a specific E1

I have a PGW version 9.5(2) in signaling mode and Cisco As5350 acting as SLT terminating 2E1 lines with another partner. E1 line1 has signaling at Time slot 1 and voice slots on rest of voice channels. E1 line 2 has only voice channels under control of signaling on E1 line1. The gateway receives traffic over IP and sends it to PSTN over those 2E1s. The task is to terminate traffic from dial-peer A, to E1line 1 and from other VoIP dial peer B to E1 line N2. Preferably the configuration and change in routing should be done at the Cisco ASserver , not on the PGW
