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)
J
Point-to-Point BRI Terminal Connection (no daisy-chaining)
J
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 use a single universal slot.
For each BRI line, two different TEI's will be assigned to two different SPID's.
The two different SPID's for each BRI line, will be related to different trunk logical port
numbers. One BRI provides two trunk logical ports when it is connected to a CO line. Each
SPID is assigned to a different TEI. This relationship is made in the initialization of the BRI
line when it is connected to the CO.
This relationship between SPID and TEI's are created as follows.
When using the SMDR reports for BRI, all incoming BRI calls will be displayed under the
CLASS column as "IVIN".
r Automatic Data Link Failure Recovery
If a data link error is detected by the BRI ETU, the system will try to recover the data link
and send the SPID to the central office. To provide this enhancement, the BRI ETU must be
able to indicate to the system when a data link error has occurred.
In addition to the BRI Interface ETU, BRI Services require the installation of NT1 Network
Terminators and interconnecting cabling.
r CO Line Service is not supported.
ISDN –BRI cannot be configured for CO Emulation.
r BRI and DID Callers with Non-Matching SPID Numbers
This feature allows you to determine whether the system will check the called party number
with the SETUP message and the SPID setup. Depending on the system programming,
this can allow DID calls to be received on BRI trunks and direct them according to the DID
Translation Table (Program 22-11).
