Install IP Telephones
The Business Communications Manager emobility strategy includes support for the Nortel
Networks i2004 and i2002 IP telephones, the Nortel Networks i2050 Software Phone, and the
NetVision and the NetVision Data portable handsets.
The system can be set to automatically assign DNs to the Nortel IP telephones. If you choose to
manually assign DNs, choose DNs from the following digital range, if possible:
Ensure that the DN type in each DN record is set to IP telephony.
• B1 line DNs can default to unused DNs from 221 to 376.
• B2 line DNs can default to unused DNs from 377 to 472.
NetVision DNs are assigned to the handsets through the H.323 section under IP Telephony on the
Unified Manager. Use the DNs within the ranges described above. If no DN is specified in the
record, the system will automatically assign one when the handset connects to the system.
For details about configuring DN records for the IP telephones and the NetVision telephones, refer
to the IP Telephony Configuration Guide.
Install Radio-Based Portable Systems
There are three radio-based systems available for the Business Communications Manager system.
Availability depends on the geographical location of the system and is determined by the region
you select for the system during system configuration.
Companion portable system
In North America, you can provide cordless access throughout your site using the Companion
cordless system. This system allows you to provide portable units that are twinned with stationary
sets. This allows you to accommodate users who are mobile within the range of the system.
Companion handsets communication through base stations that are connected to DSMs on the
Business Communications Manager. You can install a maximum of 32 handsets per DSM, since
the handsets can use either of the B channels.
“Mobility Services by Region” on page 303 lists the region profiles that can accommodate the
Companion system.
Companion sets default to DNs in the 565 to 596 DN range and use the DN type Companion.
Note: The Symbol NetVision telephones are wireless telephones, but to the Business
Communications Manager they appear as IP telephones.
