New page

SCCP can be used to change the network type of the messages. An example for this is passing from an international to a national network.

In order to achieve this you must create a SCCP entity for each network type.<br/>

To configure SCCP address translation you must define:
* MTP interconnections
* SS7 Routers
* SS7 Management
* SCCP
* SCCP Management
* GTT

==Network schema overview==

[[File:SCCP_address_translation.png]]
<br/>
*In a basic setup we would have two STPs:
** a remote STP (STPi) that sends traffic
** a local STP (STP1) that does the translation
* and a SEP that processes the SCCP messages (SEP1)

Both STPs have unique international pointcodes. The SEP has a pointcode addressable only from the internal national network.<br/>
We'll be configuring STP1.

==Configuration==

===Layer 1===
In sigtransport.conf

[sctp:stp-stpi]
type=sctp
local=100.1.1.1:2094
remote=80.0.0.1:2094
stream=false

[sctp:stp-sep]
type=sctp
local=100.1.1.1:2095
remote=100.1.1.2:2095
stream=false

===Layer 2===

In ysigchan.conf
[m2pa:stp-stpi]
type=ss7-m2pa
sig=sctp:stp-stpi

[m2pa:stp-sep]
type=ss7-m2pa
sig=sctp:stp-sep

===Layer 3===

In ysigchan.conf
[ls:stp-stpi]
type=ss7-mtp3
netind2pctype=ITU
netindicator=international
local=ITU:2
adjacent=ITU:1
link=m2pa:stp-stpi

[ls:stp-sep]
type=ss7-mtp3
netind2pctype=ITU
netindicator=national
local=ITU:100
adjacent=ITU:101
link=m2pa:stp-sep

===SS7 routers===

; We have two SS7 Routers, one for each netindicator type

[router-international]
type=ss7-router
local=ITU,2
netindicator=international
transfer=yes
management=mgm-internat

[router-national]
type=ss7-router
local=ITU,100
netindicator=national
transfer=yes
management=mgm-national

===SS7 Management===
; Define the SS7 management for each of them

[mgm-internat]
type=ss7-snm
local=ITU,2
netindicator=international
changesets=yes
router=router-international

[mgm-national]
type=ss7-snm
local=ITU,2
netindicator=national
changesets=yes
router=router-national

===SCCP===

; Define SCCP one for each router

[sccp-international]
type=ss7-sccp
pointcodetype=ITU
netindicator=international
localpointcode=2
router=router-international
management=sccp-mgm-internat

[sccp-national]
type=ss7-sccp
pointcodetype=ITU
netindicator=national
localpointcode=100
router=router-national
management=sccp-mgm-nat

===SCCP Management===
; Define SCCP Management for each SCCP

[sccp-mgm-internat]
type=ss7-sccp-itu-mgm

[sccp-mgm-nat]
type=ss7-sccp-itu-mgm

===GTT===

; Define GTT for each SCCP

[gtt-international]
type=ss7-gtt
sccp=sccp_international
debugname=GTT-international

[gtt-nat]
type=ss7-gtt
sccp=sccp_national
debugname=GTT-national

===Routing between SCCPs===
When routing messages between the two SCCPs on the same machine the '''sccp''' parameter with the name on the SCCP component that will send the message to the destination must be added.

Example in regexroute.conf:

[extra]
sccp.route=110,gt,gtt

[gtt]
; Route GT from international SCCP
^4074012345$=local;RemotePC=101;sccp=sccp_national

; Route GT from national SCCP
^10955311572$=local;RemotePC=1;sccp=sccp_international
