Configuring call routing 345
SmartWare Software Configuration Guide 31 • CS context overview
Selecting PCM law compression
The PCM law-select specifies the voice characteristic compression curve. Two values are possible: a-Law (used
in Europe) and µ-Law (used in the USA).
Procedure: To set the general CS parameters
Mode: System
Configure: General CS settings
The following example configures the general CS parameters
node>enable
node#configure
node(cfg)#system
node(sys)#clock-source 1 0
node(sys)#ic voice 1
node(ic-voice)[1]#pcm law-select aLaw
node(ic-voice)[1]#exit
Configuring call routing
Calls through a SmartNode can be routed according to a set of routing criteria. The entity that manages call
routing is called the call router. Calls are routed from one CS interface to another. The call router determines
the destination interface for every incoming call. It supports complex call routing and call property manipula-
tion (e.g. number manipulation) functions. See chapter 40, “Call router configuration” on page 456.
Call routing occurs in the context CS element between several CS interfaces. Accordingly, a CS context and
two or more CS interfaces must be created.
Step Command Purpose
1
node(sys)#clock-source internal
or
node (sys)#clock-source slot-number port-number
Generates the reference clock internally
or specifies a specific port to receive the
reference clock.
2
node (sys)#ic voice slot-number
Changes to ic_voice mode.
3
node (ic-voice)[slot-number]#pcm law-select {
aLaw | uLaw }
Selects the PCM aLaw for Europe or
uLaw for USA.
