NEC DSX Software Manual

Direct Inward Dialing
100 ◆ Features DSX Software Manual
- If the telco doesn’t send any digits into the system, or
If the digits sent by the telco don’t correspond to a DID Translation Table entry, or
If the destination extension is out of service:
The call follows the 3112-Termination routing for the line. This includes the settings for Day Ter-
mination, Day Overflow, Night Termination, and Night Overflow. The call is handled the same as
an analog line and follows the normal system timers.
- If the digits sent by the telco have a DID Translation Table entry with no corresponding destination
programmed:
No routing occurs and the caller hears busy tone.
❥ DID Camp-On
DID Camp-On sets what happens to DID calls to busy extensions when you have Busy/DND Intercept
disabled. With DID Camp-On enabled, a call to a busy extension camps-on to the extension. Without
DID Camp-On, the caller to the busy extension just hears busy tone (or follows the intercept program-
ming if enabled).
By default, DID Camp-On is disabled.
❥ DID Routing to Voice Mail
If a DID call is unanswered and is eventually routed to voice mail, it will route to the mailbox of the ini-
tial DID destination. This is true regardless of whether the call routed to voice mail via DID Line Over-
flow, Call Forwarding, or Extension Hunting.
ANI/DNIS Support
The system is compatible with telco's T1 Automatic Number Identification (ANI) and Dialed Number Infor-
mation Service (DNIS) services. ANI/DNIS services can be provided on T1 loop start, ground start, and DID
lines (but not E&M). ANI/DNIS Compatibility provides:
❥ Selectable Receive Format
You can set up the system for compatibility with any combination of ANI, DNIS and Dialed Number
(Address) data provided by the telco.
❥ Flexible Routing
The system can route the incoming call based on the received DNIS data and the entries stored in the
DID Translation Table.
❥ Caller ID
The system can use the received ANI data to display the caller’s number on the called extension’s dis-
play. The ANI data can be up to 10 digits long. (Note that the T1 PCB can alternately receive normal
FSK-based Caller ID if provided by the telco, but cannot route on that data.)
