Configuring Call Routing

Working with Call-Route profiles

The next set of commands creates another Call-Route profile for the Hybrid Access card and sets the preferred source to the second E1 interface in slot 2:

admin> new call-route { { { shelf-1slot-3 0 } 0 } 2 } CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 1 } read

admin> set preferred-source = { { 1 2 2 } 0 }

admin> write

CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 2 } written

Note that the default Call-Route profile for the Hybrid Access card was not modified. It still specifies a general route for the card as a whole, as shown in the following listing:

admin> get call-route { { { shelf-1slot-3 0 } 0 }0} [in CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 0 }] index* = { { { shelf-1 slot-3 0 } 0 } 0 } trunk-group = 0

phone-number = ""

preferred-source = { { any-shelf any-slot 0 } 0 } call-route-type = digital-call-type

Example with six E1 lines in an MFR bundle

If the MFR bundle aggregates enough bandwidth to utilize all of the channels on a Hybrid Access card (up to 186, or six E1 lines), you can create a single Call-Route profile mapping the E1 card to the Hybrid Access card. Only six of the E1 lines are usable for MFR, however.

For example, the following commands modify the default Call-Route profile to specify the E1 card in slot 2 as the preferred source for the card:

admin> read call-route { { { shelf-1slot-3 0 } 0 } 0 } CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 0 } read

admin> set preferred-source = { { 1 16 0 } 0 }

admin> list

[in CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 0 } (changed)] index* = { { { shelf-1 slot-3 0 } 0 } 0 }

trunk-group = 0 phone-number = ""

preferred-source = { { shelf-1 slot-16 0 } 0 } call-route-type = digital-call-type

admin> write

CALL-ROUTE/{ { { shelf-1 slot-3 0 } 0 } 0 } written

Concentrating multilink calls on one Hybrid Access card

Multilink calls that add channels dynamically might inadvertently use channels distributed across multiple Hybrid Access cards, which causes a performance penalty for those calls. You can use Call-Route profiles to direct the system to route calls received on a particular trunk to a single Hybrid Access card.

In this example, the system has three T1 cards installed in slots 1, 2, and 3. Slot 1 uses trunk groups 4 and 5, slot 2 uses trunk groups 6 and 7, and slot 3 uses trunk groups 8 and 9. The system also has three Hybrid Access cards, in slots 4, 5, and 6.
