Call Type

When a call is received the SIC showing its type and capacity required are checked by the
DBS. Calls of a type which are not supported by the DBS are terminated.

DASS Incoming Ringing

Calls without DDI information will ring as if they were a standard analogue line. When A DDI
call is received it will ring as per the DDI settings. If the system is not set to use DDI numbers
and a DDI call is received it will ring as if it were a normal incoming call.

Direct Dial In

The DBS can connect calls directly to extensions using DDI information of 1 to 6 digits sent
from the network. Up to 144 DDI numbers can be specified in a programming look up table to
route calls to an extension or group of extensions. A maximum of 50 groups of 8 member
extensions can be created via programming.

In the DDI look up table each DDI number can only be specified once and route to one
extension or group. Extensions and groups can be the recipient of calls to multiple DDIs by
assignment to these DDI numbers in the table.

An incoming DDI call has priority over other incoming call types at the destination extension,
overriding DISA , private line and other incoming calls.

Delayed ringing does not operate with DDI calls.

Auto answer is always operative for DDI calls regardless of system settings.

DDI to Extensions

When a DDI call is routed to an extension hunting call forward and coverage groups will
operate as normal.

A extension cannot receive a DDI call under the following conditions.

Off hook
While receiving another call
While being used for programming
The extension to which call forward has been set cannot receive a call
While DND is set
While absence message is set
SLT overload (system cannot drive the ringer on any further SLTs)
While holding an internal or non appearing line and the DDI is also non appearing
While hunting is disabled
