Moving and replacing telephones
When the Business Communications Manager system is on, you can replace a telephone with a
new one and the new set will pick up the current programming, if it is the same model as the set
that was removed. A new telephone is one that was not previously in service within the system.
For a description of the telephones that can be used on the Business Communications Manager
system, refer to “Telephones and adapters” on page 48.
For information on installing and replacing the 20XX IP telephones, refer to the IP Telephone
Configuration Guide.
Determining the status of a telephone
To discover the system status of a telephone, you must know the DN of the set and which port on
the Business Communications Manager the set is connected to. If the tables in Chapter 13,
“Installing optional telephony equipment,” on page 157 were filled out when the telephone were
installed, refer to them to determine the port each set is attached to.
To find out the status of a set:
1 Open the Unified Manager.
2 Click on the keys beside Resources, Media Bay Modules.
3 Click on the bus number (DS30 bus) assigned to the media bay modules supporting the
telephone line.
4 Click Port #.
Port # is the port connected to the telephone.
5 Click Channels.
6 Click on B1 or B2 to view the appropriate DN number.
7 State indicates the state the set is in.
Note: IP telephones are listed under DS30 01. Ports for IP telephones are automatically
assigned as the telephones are registered to the system.
