Normal/Service switch must be placed in the Normal position.
Functionality Description
Automatic Number Identification (ANI) information from the carrier is
treated exactly the same as an inbound ICLID (Caller ID) number. Calls
can be routed, placed in the unanswered call table, sent out to the CTI
Module port on a keyset, and run through the number to name
translation table. The
same manner as ICLID.
Dialed Number Identification Service (DNIS) information from the
carrier is treated using DID line rules. DNIS calls are routed based on the
DID routing table.
ANI/DNIS is a combined format, where the system waits for the ANI/DNIS
information from the carrier. When it is received, the system routes the
call using ICLID processing.
This board supports standard D4 framing format with robbed bit
signaling. The Extended Super Frame (ESF-B8ZS) format is also
supported.
The board can support TIE, Loop and Ground start signaling
emulation per channel.
The board requires an external CSU unit.
The T-1 board can accept two (2) DTMF-A units in a daughter board
type arrangement. This unit has 4 DTMF Receivers installed on it. This
board can be installed on the SLIB, and T1IB boards.
The board has a 15-pin D Sub connector for connection to a CSU unit.
The card ejector tabs are color coded white.
If this information is not found in the ICLID Route Tables, the DNIS
information is compared to the DID table for a match. The call is then
routed based on the DID tables.
If a match is not found on either the ANI or DNIS number, the call is
routed based on normal CO line operation (CO Ringing Assignments).
