Configuring the precall service tables 387
SmartWare Software Configuration Guide 33 • CS interface configuration
• interrogate-cw—Detects whether or not the call-waiting supplementary service is active on the interface
that uses the precall service table.
Note Currently you can only use precall service tables on FXS interfaces.
Procedure: To create precall service table and use it on an FXS interface
Mode: Context CS
Example: Create and use a precall service table
The following example shows how to create a precall service table that treats *43# as activation command for
the call-waiting supplementary service, while #43# is used to deactivate call-waiting and *#43# is used to query
the call-waiting supplementary service:
node(ctx-cs)[switch]#precall-service-table SUPP-SVC
node(pcs-tab)[SUPP-SVC]#map *43# to activate-cw
node(pcs-tab)[SUPP-SVC]#map #43# to deactivate-cw
node(pcs-tab)[SUPP-SVC]#map *#43# to interrogate-cw
node(pcs-tab)[SUPP-SVC]#exit
node(ctx-cs)[switch]#interface fxs IF-PHONE
node(if-fxs)[IF-PHONE]#use mapping-table precall-service SUPP-SVC
node(if-fxs)[IF-PHONE]#exit
node(ctx-cs)[switch]#
Step Command Purpose
1
node(ctx-cs)[switch]#precall-service-
table table-name
Creates a new table that maps special numbers into
supplementary service invocation commands
2
node(pcs-tab)[table-name]#map special-
number to command
Adds a new entry to map a special-number into a
supplementary service invocation command.
3
Repeat Step 2 to add other special number map-

4
node(pcs-tab)[table-name]#exit Returns to context CS Configuration Mode
5
node(ctx-cs)[switch]#interface fxs if-name Enters FXS Interface Configuration Mode of inter-
face if-name
6
node(if-fxs)[if-name]#use mapping-
table precall-service table-name
Uses the precall service table created with step 1 to
4 on this FXS interface.
