DID & DNIS ROUTING
Direct Inward Dialing (DID) allows a caller outside a company to call an internal extension without
having to pass through an operator or an Auto Attendant. Dialed Number Identification Service
(DNIS) works in a similar manner and is typically only available on inbound 800 and 900 service.
DID and DNIS on the VS1 System can only be used with a Telecor T1 Interface Card, and T1
service must be ordered from your local service provider. The dialed digits are passed down the line
from the CO and the VS1 then completes the call to an extension. Your Service Provider will give
you a block of DID or DNIS numbers to use, which are frequently provided in blocks of 100
numbers (e.g. 2001 to 2100). You must give your Service Provider the FCC ID number from the
label on the T1 Interface Card.
For more information on T1, see “Installing a T1 Interface Card,”
In addition to DID and DNIS, the T1 Interface Card allows for Automatic Number Identification
(ANI).
ANI reports the number of the calling party. This is similar to Caller ID on an analog line.
However, the only information provided is the number from which the caller is calling. Name
information is not sent by the Service Provider.
The numbers received from the phone company can be a maximum of 15 digits for DID, DNIS and
ANI. The VS1 system supports DID (or DNIS) and ANI with specific digit sequences sent by the
Service Provider. Only when using both DID (or DNIS) and ANI do incoming signals need to be
separated in order to be recognized by the VS1 system. For example, the digit sequences for the
calling number (913) 888-7936 with the DID routing number of 274 are:
ANI and DNIS = * ANI * DNIS *
*9138887936*274*
ANI = * ANI **
*9138887936**
DNIS = ** DNIS *
**274*
Note
If the Service Provider sends a pure digit stream (no * separating characters), the digits
are considered ANI unless DID Routing is selected for the CO port.
Configuring a Port for T1 Service
There are three steps involved in configuring a port for T1 Service:
•
Identifying the port for T1 Card usage (
accomplished through Adapter Setup - see page 86.
)
•
Assigning the port as a CO Line.
•
Configuring the port for DID or DNIS.
Assigning the Port as a CO Line
1.
Select
Port Configuration
in the Tree Control display.
•
The
Port Configuration
pane appears.
2.
From the
Configuration
drop-down box, select the configuration where you want to make
changes.
Note:
If you have more than one configuration on your system you must set up each
configuration.
3.
Beginning at Port 97 (for one T1 Card) or Port 65 (for two T1 Cards) and ending at port 128,
every fourth port is reserved, and the others are unassigned. The reserved ports are a function of
