Meridian Link Release 5C/CCR Release 3C Diagnostic and Maintenance Guide
A Control DN is a special ACD DN, configured in Meridian 1, to which no
agents are assigned. To control calls in the CDN you need to create a script,
otherwise the calls are put into the default mode. A call script is associated
with a CDN, so that all calls entering a CDN are handled by the same call
script.
See Command and Status Link.
CCR is a product that enables you to control and route Automatic Call
Distribution (ACD) calls entering your Meridian 1 system. You can
provide a specific recorded announcement, music, and so on, before
assigning a call to an agent.
An attribute of a trunk. The CO passes the extension number of the called
party over a DID trunk to the PBX when offering a call to the PBX. The
PBX is then able to automatically route the call to the extension without
requiring operator/attendant assistance. In this way, a single trunk can
terminate calls for many different extensions (but not simultaneously).
The number that identifies a telephone set on a PBX or in the public
network. It is the number that a caller dials in order to establish a
connection to the addressed party. The DN could be a local PBX extension
(local DN), a public network telephone number, an ACD-DN, or the pilot
or group number for an ACD queue.
A service provided on a trunk. DNIS identifies to the called system the last
3 or 4 digits of the number actually dialed by the caller. The DNIS digits
are sent as in-bank DTMF tones on non-ISDN trunks, or by using dial
pulses on dial pulse (DIP) trunks. On ISDN PRA trunks, DNIS is carried in
the called party IE field of the Q.931 Setup message.
See directory number (DN).
