Calling Line Identification Presentation and Restriction

553-3001-218 Standard 2.00
Testing ISDN BRI functions
5 Verify the call was forwarded to the attendant by answering the call at
the attendant console. The attendant console will display the
call-originating identification number and the notification of call
redirection.
6 Hang up at the call-originating ISDN BRI terminal to release the call
connection.
Calling Line Identification Presentation and Restriction allows a calling party
number (Calling Line Identification) to be shown on a called party ISDN BRI
terminal display. Use LD 27 to specify this feature when configuring the TSP
for the ISDN BRI terminal DN. See "TSP configuration procedures" in ISDN
Basic Rate Interface: Features (553-3001-380).
This feature gives the calling and the called parties the option of displaying
the calling line identification as follows:
• The called party ISDN BRI terminal must have the calling line
presentation (CLIP) parameter value set to YES to accept the calling line
identification and show it on its display.
• If there is an option on the ISDN BRI terminal that enables the calling
party to allow or restrict the presentation of the calling line ID on a per
call basis, select the option to allow presentation. This option on the
terminal overrides the PRES parameter values entered in the TSP data
block when configuring the TSP. This depends on the telephone
configuration default. See "TSP configuration procedures" in ISDN
Basic Rate Interface: Features (553-3001-380).
Procedure 30
Perform a Calling Line Identification Presentation test
1 Configure both the calling and the called party ISDN BRI terminal DN
with CLIP = YES and PRES = YES.
2 Place a call from one terminal to the other and observe the display on the
called party ISDN BRI terminal. The Calling Line Identification should
be displayed during ringing and for the duration of the call.
3 Release the call at the called or calling party terminal.
