Electra Elite IPK II Document Revision 4C
ISDN Compatibility 2 - 639
Basic Rate Interface (BRI)
Caller ID Name to Single Line Telephone is NOT supported for ISDN (BRT) Trunks.
The system is compatible with ISDN Basic Rate Interface (BRI) services. BRI services
currently supported include:
Basic BRI Call Control (BCC)
Point-to-Point BRI Terminal Connection (no daisy-chaining)
Multipoint BRI Terminal Connection (daisy-chaining)
BRI services require the installation of BRT(4)-U20 ETUs. Each BRT(4)-U20 ETU has four
BRI circuits. The BRT(4)-U20 ETU uses a single universal slot.
For each BRI line, two different Terminal Endpoint Unidentified (TEIs) are assigned to two
different Service Profile Identifiers (SPIDs).
