24 Overview
Incoming Non-DDI numbering facilities
If a DASS2 route is configured as non-DDI, then operation is much the
same as for a standard Exchange Line route. Incoming calls will usually be
routed directly to the attendant. The system offers the following alternative
methods of termination:
•
Auto-terminate
•
Private Line
Auto-terminate
If a route is defined as an auto-terminate route, then each trunk member
of the route can be assigned an auto-terminate DN. Any incoming calls on
the trunk will then be routed to this DN. This feature can be applied to DDI
as well as non-DDI DASS2 trunks.
Private Line
This feature applies to non-DDI routes only. For incoming calls, it offers
the same facility as Auto-terminate, that is, termination on a preassigned
DN. For outgoing calls, a given trunk can only be accessed from the
extension on which the assigned DN is located.
Dialed Number Identification Service - DNIS
DDI routes using auto-terminate or IDC may also be defined as DNIS
routes. Dialed Number Identification Service (DNIS) is an Automatic
Call Distribution feature designed to enhance call handling speed and
quality. When used with an auto-terminate DDI route, DNIS allows the
actual received digits and name to be displayed on the answering ACD
agent. This can be used to indicate the service which the caller expects
from the agent. If a route is configured as DNIS, then digit insertion and
pretranslation may not be applied. Also, the number of digits which must
be received on a DDI route is determined by the ISDN, and this may differ
from the quantity defined for DNIS display purposes on the system.
Network Routing of DASS2 Calls
Incoming DDI DASS2 calls may be routed through the private network
on DPNSS1 or non IDA trunks. To achieve this, the received digits must
be converted into the appropriate CDP steering code or BARS Special
Number.
Outgoing calls on DASS2 routes can be originated from DPNSS1 trunks.
The way to configure this type of access is described in the Network
Numbering section of DPNSS1 (NN43001-572).
