Page 100 of 120 Testing ISDN BRI functions
553-3001-218 Standard 2.00 September 2004
The tests are divided into:
• voice calls
• circuit-switched data calls
• B-channel and D-channel packet data calls, using an external packet
handler and an MPH
• ISDN BRI trunk
Voice calls
A voice call can be established between two voice terminals across a network
(ISDN or non-ISDN), between two terminals on the same system, and
between two terminals on the same DSL. Acceptance testing of ISDN BRI
voice calls is conducted when testing the following system features supported
by ISDN BRI terminals.
• Call Hold
• Call Waiting
• Call Forward No Answer
• Calling Line Identification Presentation and Restriction
• ISDN BRI National ISDN-1 Conference and Call Join
• Special ISDN BRI Hunting
• ISDN BRI ETSI Conference
• ISDN BRI ETSI Call Forwarding Unconditional
• ISDN BRI National ISDN-1 Call Forward All Calls
Call Hold
Call Hold is used to place an active call on hold to allow answering an
incoming call or placing an outgoing call. After releasing an incoming or an
outgoing call, retrieve the call on hold.
Note: The following test requires the terminal placing the calls on hold
to have multiple DN appearances. Otherwise, this test cannot be
performed as written.
