This read-write OCTET STRING (1 to 20 bytes) is the remote-network counterpart to svcPrefixLocalGatewayAddress, used to replace the calling party number for calls exiting the network at this port when egress address translation is in the appropriate mode, using the same E.164/ATM-endsystem encoding. Where the local gateway address substitutes this network's own presented number, the remote gateway address is used when tunneling or translating toward a specific remote gateway on the far network. An engineer configuring address translation toward a specific known peer gateway would set svcPrefixRemoteGatewayAddress to that peer's gateway address so translated calls are correctly directed.
