Configuring the ISDN PRA Service

This topic is applicable to the scenario where the ISDN users are connected to the Huawei MA5680T   /MA5603T/MA5608T through the ISDN primary rate interface (PRI).

Add the EDTB board.
According to the data plan, add an ISDN PRA service board to slot 0/2.
huawei(config)#board add 0/2 h802EDTB
Add an IUA link set and IUA links.
In the SIGTRAN mode, configure the SIGTRAN protocol stack. Add an IUA link set, and then add IUA links.
huawei(config)#sigtran
huawei(config-sigtran)#iua-linkset add 1 mgid 0 jointly-work enable trafficmode override
iid-map 2 pendingtime cs-mode client
huawei(config-sigtran)#iua-link add 15 1 1401 10.13.4.116 1400 10.14.1.2
jointly-work-with primary-mgc priority 3
 NOTE:
All the ISDN call control messages are sent from the IUA link to the softswitch, whereas the system uses the bearer control messages to communicate with the softswitch through H.248.
Configure the ISDN PRA user data.
huawei(config-sigtran)#quit
huawei(config)#esl user
huawei(config-esl-user)#mgprauser add 0/2/0 0 1 interfaceid 1 terminalid 512

 NOTICE:
Each ISDN PRA user occupies 32 TIDs. You need to input only the first TID when adding an ISDN PRA user.
When the TID profile to which the ISDN PRA user of the MG interface is bound is not a layering profile, the TID must be configured and cannot be within the configured TID range.
When the TID profile to which the ISDN PRA user of the MG interface is bound is a layering profile, the configuration MA5600T    of the TID parameter is not available because the system automatically allocates the TID.
