Patton electronic SmartNode 4110 Series Configuring the interface mapping tables, Table table-name

SmartWare Software Configuration Guide 33 • CS interface configuration

In the environment of the CS interfaces, it is necessary to specify whether the call will be routed directly to another CS interface (basic interface routing) or to a first lookup table from the call router (advanced call rout- ing).

In this chapter. only the configuration task on a CS interface is described. For configuration of the call routing tables, mapping tables and call services refer to chapter 40, “Call router configuration” on page 456, which also describes the difference between the two levels of call routing in more detail.

Procedure: To configure basic interface routing

Mode: Context CS

Step	Command	Purpose
1	node(ctx-cs)[switch]#interface if-type if-	Enters CS Interface Configuration Mode and config-
	name	ure interface if-typewith name if-name
2	node(if-type)[if-name]#route call dest-	Specifies a destination interface for incoming calls
	interface if-name	(basic interface routing) or a destination table or call
	or	service (advanced call routing)
	node(if-type)[if-name]#route call dest-
	table table-name
	or
	node(if-type)[if-name]#route call dest-
	service service-name
3	node(if- type)[if-name ]#exit	Returns to CS context configuration mode
4		Repeat steps 1–3 for all the required CS interfaces

Example: Configure call routing

The following example shows how to configure basic interface routing.

node>enable

node#configure node(cfg)#context cs

node(ctx-cs)[switch]#interface pstn IF-PBX1 node(if-pstn)[IF-PBX1]#route call dest-interface IF-H323-0 node(if-pstn)[IF-PBX1]#exit

node(ctx-cs)[switch]#

Configuring the interface mapping tables

Call router mapping tables are normally used by the call router to manipulate call properties during the call setup phase, i.e. when a call arrives on a CS interface and is routed to another interface through routing and mapping tables. This imposes a limitation to call property manipulation: When a call property like a party’s number is changed during a call, the call is not routed through the call router again and thus, the mapping tables are not processed for the new number. Call property manipulation, e.g. removing a prefix from a num- ber, cannot be done for the new number.

Consider, for example, an ISDN call, which may send a connected party number in the Connect message. This connected party number has the same meaning as the original called party number, but may differ from it. Another example of a call property that changes during a call is a SIP call transfer. A SIP call may be transferred
