TeleVantage supports ISDN BRI trunks.
Note:
Connecting BRI devices such as BRI phones to Dialogic ISDN BRI boards is not
supported.
ISDN BRI carrier requirements
TeleVantage supports the following ISDN BRI protocols. The drivers for these protocols are
provided on the TeleVantage Drivers CD. Contact your TeleVantage provider if your protocol
is not listed here.
ISDN BRI Protocols
Q 5ESS (ATT 5ESS BRI)
Q DMS100 (Northern Telecom DMS100 BRI)
Q NTT (Japanese INS-Net 64 BRI)
Q NET3 (EuroISDN BRI)
Q NI1 (National ISDN 1)

Additional required hardware for ISDN BRI service
To support ISDN BRI service, you need the following:
Q Dialogic shielded breakout box. Part number 89-0592-001.
Q Dialogic SCSI-3 BRI breakout box cable. Part number 99-2280-003.
Q Network Termination type 1 adapter (NT1). Typically supplied by the phone
company. Connect the NT1 between TeleVantage and the digital line coming in from
the phone company.
All BRI/x-PCI boards require an NT1.
Q Cable. Connects the NT1 to the Dialogic board. See the Quick Install Card included
with your Dialogic BRI board for details. BRI/x-PCI boards require a special cable with
pins 3 and 4 crossed, pins 5 and 6 crossed, and pins 1, 2, 7, and 8 wired straight through.
Shared voice resources
Unlike other Dialogic trunk boards, the BRI boards do not supply any voice resources
to handle auto attendants, voice mail access, or other TeleVantage features. To use BRI
boards with TeleVantage, you must install extra Dialogic boards that provide shared
voice resources. See “Supported voice resource boards” in Chapter 4 in Installing
Dialogic Telephony Components for a list of Dialogic boards that provide shared voice
resources.
