User's Manual

on one TN and register from the IP Deskphone to each configured key. This applies to systems
using Meridian Communications Adapter (MCA) – Multiple Appearance DN (MADN).
Each registration must have the same Login ID and Authentication ID. The first registration
maps to the lowest numbered DN key. Subsequent registrations are assigned DN keys in
ascending order of the key numbers.
The following example shows several MCR keys configured on the same DN, on one TN:
TN 100 0 0 1
UEXT/SIPL
With:
SIPU user1
SCPW xxxx
KEY 0 MCR 5000
KEY 1 HOT U xxxx
KEY 2 MCR 5000
KEY 3 MCR 5000
Multiple Appearance Directory Number
The Multiple Appearance Directory Number (MADN) feature operates differently depending
on the type of Communication Server. For instance, the MADN feature operates differently on
the Communication Server 2000 than the Communication Server 1000.
Communication Server 1000
CS 1000 Multiple Appearance Directory Numbers (MADN) provides the following features:
• Several devices (TNs) share a common Directory Number (DN).
• When the DN receives a call, all devices ring.
• You can configure two call arrangements; Single Call Arrangement (SCA) and Multiple
Call Arrangement (MCA).
Single Call Arrangement
Single Call Arrangement (SCA) MADN allows only a single active call on the DN, regardless
of the number of DN appearances:
• A call on a DN appearance makes all other appearances busy (they cannot receive or
make calls).
• Activity on one DN appearance reflects on other appearances; this is achieved by using
the Event Dialog SIP feature. For more information, refer to RFC 4235.
• SCA MADN provides Automatic Privacy for telephones that share a DN. When a call is
in progress on the DN, no other telephone on which the DN appears can bridge into the
call, unless the call is put on hold
