98 Testing ISDN BRI functionsISDN BRI ETSI Call Forwarding UnconditionalThe ISDN BRI ETSI Call Forwarding Unconditional (CFU) supplementaryservice allows an incoming call to an ISDN BRI terminal to be forwardedto a predetermined destination, within or outside the system. The call isforwarded whether the user is busy or idle.An ISDN BRI user can assign the same address or a different addressfor voice or data calls being forwarded. Calls can also be forwarded to anISDN BRI terminal or a non-ISDN BRI terminal. When the CFU feature isactivated, outgoing calls can still be made from the ISDN BRI terminal.The ETSI supplementary service provides Call Forwarding capabilities to allusers on the access (that is, all the DNs defined under a Digital SubscriberLoop (DSL), or an individual user (that is, a DN).Procedure 35Perform an ISDN BRI ETSI Call Forwarding Unconditional testStep ActionThe following test is for forwarding a voice call from an ISDN BRI M5317 set.1 Set up ISDN BRI ETSI Call Forwarding Unconditional in Overlay 27(refer to the "Configuring ISDN BRI features" chapter in ISDN BasicRate Interface Feature Fundamentals (NN43001-580)).a. Select the ETSI protocol for the DSL.b. Configure the call type (enter voice call type) and Call Forward(enter voice call forward).2 On the ISDN BRI terminal, configure ISDN BRI ETSI Call ForwardUnconditional.3 Configure two DN appearances on the ISDN BRI terminal (use thefirst DN to forward a call, and the second DN to place a call to testthe call forward). On some ISDN BRI terminals, the second DNappearance allows the user to initiate the second call.4 Activate ISDN BRI ETSI Call Forwarding Unconditional on the ISDNBRI terminal, for the first DN:a. Press the Forward key.b. Dial the number where calls are to be forwarded.c. Press the Forward key.Note: Call Forward Reminder Tone should be provided to theISDN BRI terminal.5 From the second DN, place a call to the first DN, to verify that thecall ha been forwarded.Nortel Communication Server 1000ISDN Basic Rate Interface Installation and CommissioningNN43001-318 01.02 StandardRelease 5.0 20 June 2007Copyright © 2003-2007, Nortel Networks.
