Version 6.6 485 October 2014
Installation & Operation Manual 38. Configuring the PSTN Subsystem
38.6.4 Configuring the MTP3/M3UA Application
The following entities are relevant to the MTP3/M3UA application:

SS7 Data Link – represents the MTP2 signaling link connected to the PSTN
network

MTP3Group – represents the complete MTP3 configuration applied to specific
Media Gateway board

SS7Node – represents the signaling node in the SS7 network

SS7Linkset – represents a collection of signaling links between the Media
Gateway board and the adjacent signaling node

SS7Routeset – represents a collection of routes ( essentially linksets) that
constitute a routing path between the Media Gateway board and the destination
signaling node

SS7LinksetLink – represents properties of a specific signaling link as part of
the specific linkset

SS7Route – represents properties of a specific linkset as part of the specific
routeset

UAL Group – represents the SCTP association between the Media Gateway
and the Softswitch

M3UA Routing Group and Context – defines routing rules for M3UA
messages based on their source point code and service indicator. For example,.
you may define that all M3UA messages from OPC 0xA will be routed to ASP 1,
while messages from OPC 0xB will be routed to ASP 2.

MTP2Profile – defines the MTP2 signaling link timers and configuration

SS7NodeTimers – defines the signaling node timers

SS7LinksetTimers – defines the linkset timers
This simplest configuration contains minimum redundancy capabilities. For full
redundancy configuration capabilities, see Redundant Configuration on page 499.
 To configure the MTP3/M3UA application:
1. Create and configure an SS7 Data Link for each signaling link connected to the
PSTN network:
a. Click
to access the Media Gateway status screen.
b. Select the desired Media Gateway board.
c. In the Navigation pane, select PSTN
SS7 SS7 Data Links; the SS7
Data Links list is displayed.
d. Use the
or buttons to add or remove entries.
e. Select a specific row and then in the configuration pane, click SS7 Data Link
Settings; the SS7 Data Link Settings screen is displayed.
f. Configure SS7 Data Link properties according to the tables 'SS7 Data Link
Properties - Data Link General Info Tab' and 'SS7 Data Link Properties -
Data Link MTP Tab'.
Make sure to configure Layer2Type as MTP2 and Layer3Type as MTP3.
