View source for SEP SCCP configuration

When using SCCP in a SEP, the SCCP must have a SCCP application above it to process the messages. This is usually a TCAP application.<br/>

To configure a SCCP layer on a SEP you need the following:
* [[How_To's#SS7_Setups|MTP]] interconnections
* SCCP layer
* SCCP management
* TCAP layer

==Network schema overview==

Below is the schema of the network we are trying to configure. We'll be configuring SEP1. <br/>

[[File:STP_SCCP_config.png]]

==SEP configuration==

===Layer 1===

In sigtransport.conf

 [sctp:SEP1-STP2]
 type=sctp
 local=100.1.1.5:2092
 remote=100.1.1.1:2092

===Layer 2===

In ysigchan.conf
 [m2pa:SEP1-STP2]
 type=ss7-m2pa
 sig=sctp:SEP1-STP2

===Layer 3===

In ysigchan.conf
 [ls:SEP1-STP2]
 type=ss7-mtp3
 netind2pctype=ITU
 netindicator=national
 local=ITU:20
 adjacent=ITU:10
 link=m2pa:SEP1-STP2

===SCCP===
In ysigchan.conf
 [sccp]
 type=ss7-sccp
 pointcodetype=ITU
 netindicator=national
 localpointcode=10
 management=sccp-mgm

===SCCP management===
In ysigchan.conf
 [sccp-mgm]
 type=ss7-sccp-itu-mgm
 
 ;  STP1 is interested in our state
 
 ; Concerned point code 10
 concerned=10
 
 ; Local Subsystems 6 and 7
 concerned=10:6,7

If you were to have another STP, then it will also be concerned about our state and you would add another configuration: ''concerned=stp2_pc'' and ''concerned=stp2_pc:6,7'' in this section.

===TCAP - SCCP application===

In ysigchan.conf
 [tcap-hlr]
 type=ss7-tcap-itu
 local_SSN=6
 default_remote_SSN=15
 print-messages=true
 sccp=sccp
 transact_timeout=600
 max_timeout_checks=5
 floodevents=100

In camel_map.conf

 [tcap hlr]
 tcap=tcap-hlr
 host=127.0.0.1
 port=16101
 type=MAP
 print-messages=true
 add-encoding=false
 
 [local hlr]
 translator=hlr
 capabilities=USSD
 export_xml_as=both
 ussd-string=octets
 ussd-decode=all
