Programming Operations Guide
Incoming calls: If your system is networked with other systems, you will also need to determine a
private access code that tells your system when a call is to be dialed out over the private network
instead of over the public network. This access code is also entered under
Services, Telephony
Services, General settings, Access codes. This code is included as part of any destination code or
dialing sequence that is to be routed over the private network.
MCDN special call types: If your system is networked to other types of systems, such as
Meridian 1, which sends calls through one or more Business Communications Manager systems to
the public network, you need to specify specific call-type codes. These codes append to the
incoming dial string, so that the call-type remains intact as it passes through the Business
Communications Manager call processing:
Calls coming in over private networks or PRI/BRI lines can either terminate at one telephone,
called the prime telephone, or target lines can be set up for each telephone or group of telephones
to which the calls are directed. As with other incoming calls, these calls can have a public or
private call type that matches to a public or private received number assigned to a target line.
Outgoing calls: Other network codes include the information about private and public dialing
codes that you enter under Services, Telephony Services, General settings, Dialing Plans
