ISDN Compatibility

• Description
ISDN-BRI (Integrated Service Digital Network - Basic Rate Interface) is a telephone
network service that provides two B-channels (2B+D) for voice call trunking. The B-
channels are used to provide two CO/PBX type connections. Caller ID is a standard
feature on ISDN-BRI provided trunks. Caller ID indication displays the calling party
telephone number on the LCD of the Multiline Terminal for CO incoming calls. This
interface provides voice communication path only.
Basic Rate Interface (BRI)
Your system also provides compatibility with ISDN Basic Rate (BRI) services,
including:
SMDR Includes Dialled Number
The SMDR report can optionally print the trunk's name (entered in system
programming) or the number the incoming caller dialled (i.e., the ISDN DDI digits). This
gives you the option of analysing the SMDR report based on the number your callers
dial. When using the SMDR reports for ISDN, all incoming BRI calls will be displayed
under the CLASS column as "IVIN".
Display Shows Why Caller ID is Not Available
With Caller ID enabled, the system will provide information for ISDN calls that do not
contain the Caller ID information. If the Caller ID information is restricted, the telephone
display will show "PRIVATE". If the system is not able to provide Caller ID information
because the telco information is not available, then the display will show "OUT OF
AREA".
Calling Party Number Notification
The system can provide calling party number notification for outgoing ISDN calls.
When a call is made on an ISDN line by an extension, the system will send the
identification for the extension placing the call, if it's programmed. If there is no
Extension Calling Number assigned, the system will send the calling number for the
ISDN trunk. If both the extension and trunk information is programmed, the extension
information will be sent as it takes priority. When the option for calling party sub-
address is on, the extension number will be sent as the sub-address information. Both
the calling party number and calling party sub-address are sent in a SETUP message
as the calling party information element and a calling party sub-address information
element.

BRI services require the installation of BRI Interface PCBs (2BRIU or
4BRIU). Each 2BRIU Interface PCB has two BRI circuits, while the 4BRIU
Interface PCB has four BRI circuits. The BRI Interface PCBs install into the
