Chapter 3 - System Installation
†
This board supports standard D4 framing format with robbed bit signaling. Extended
Super Frame (ESF) format is also supported.
†
The board requires an external CSU unit.
†
The T1 board can accept two DTRU4 units in a daughter board type arrangement. Each
unit has 4 DTMF Receivers installed on it.
†
The board has a 15-pin D Sub connector for connection to a CSU unit.
†
The card ejector tabs are color coded white.
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
XTS system provides call progress tones in 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. 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).
The following table summarizes the operation of the system.
Table 3-9: Call Routing Criteria
ANI DNIS Operation
N N Calls routed based on normal CO operation (CO Ring Assignments.
N Y Calls routed based on DID tables with DID operation.
Y N Calls routed based on ICLID routing and ICLID operation.
Y* Y Calls routed on ICLID first, if no route is found, the DNIS digits are
compared to the DID table. If no route is found in the DID table the
call is routed based on CO line Ringing Assignments.
*If both ANI and DNIS calls are routed -- the following table summarizes what is displayed at the phone.
The T-1 card accepts ANI/DNIS information in a DTMF format only. Some carriers do
not provide ANI or ANI/DNIS in a DTMF format. Consult your local carrier for available
options.
