How to configure the SS7 trunk used by the U1900 so that the voice data and signaling data are sent through the same or different channels?

The configuration example and related interconnection parameters are list as follows: Network ID: national network Length of the signaling point code: 24-bit Signaling point: U1900:010101 Voice channel timeslot: 020202 STP (signaling timeslot): 111111 SLC:0 CIC value range: 0?31 Signaling timeslot: 16 conf add interoffice index 0 npc1 010101 conf add dsp index 0 name Eq interofficeindex 0 npc1 020202 adjacencyflag no conf add dsp index 1 name STP interofficeindex 0 npc1 111111 stpflag yes conf add mtplinkset index 0 dpx 1 conf add mtproute linksetindex 0 dpx 0 conf add mtproute linksetindex 0 dpx 1 ******config add office selectcode no 0 repeatroute no selecttype none******* conf add office no 0 officeselectcode 0 dpx 0 conf add office no 1 officeselectcode 0 dpx 1 //Add the voice channel conf add board slot 3 type dtu officeno 0 signallingtype isup startcic 0 //Add the timeslot 16 for transmitting signaling streams config modify board slot 3 type dtu tkcinboard 16-16 officeno 1 conf add mtplink linkindex 0 slot 3 trunkport 0 linksetindex 0 slc 0 ts 16

All U1900 models except the U1910 support the transmission of voice data and signaling data through different channels.

Configure the call source to enable users in the call source to make outgoing calls through a specified office route. The specific configuration is as follows: 1. Run the following commands to add call sources 1 and 2: config add callsource no 1 config add callsource no 2 2. Run the following commands to add users 5032 to 5049 to call source 1 and add users 7000 to 7019 to call source 2: config modify subscriber dn 5032 callsourceno 1 number 18 config modify subscriber dn 7000 callsourceno 2 number 20 3. Run the following commands to add rerouting analysis. In this way, when users 5032 to 5049 in call source 1 dial prefix 9 corresponding to the office route selection code 1 to make outgoing calls, calls are routed through office route 4, and when users 7000 to 7019 in call source 2 dial prefix 9 corresponding to the office route selection code 1 to make outgoing calls, calls are routed through office route 0. config add routeanalysis officeselectcode 1 callsourceno 1 officeno 4 config add routeanalysis officeselectcode 1 callsourceno 2 officeno 0

The SPC is provided by the carrier in hexadecimal notation.

The U1900 series unified gateway supports separation of voice streams from data streams for SS7 signaling. For details about the SS7 signaling configuration, see the U1900 product documentation of the corresponding version.
