Table 22 Maximum Bridged Extensions
System Device Limit
NBX 100 200
There are no restrictions on the number of secondary telephones or the
number of bridged extensions on secondary telephones.
Provided that you do not exceed the limits shown in
configure the maximum number of bridged extensions using any
combination of primary telephones and bridged extensions. For example,
on a V5000 system, you can configure 400 primary telephones with three
bridged extensions each or 300 primary telephones with 4 bridged
extensions each to reach the limit of 1200.
You can configure a different number of bridged extension buttons on a
primary and an associated secondary telephone. For example, if a primary
telephone has 5 bridged extensions, you can configure one of the
secondary telephones to have fewer (1 through 4) bridged extensions.
However, if all of the primary bridged extensions are in use, the person at
the secondary telephone will not be able to see all the calls.
You can define any one telephone as either a primary telephone or a
secondary telephone, but not both. If the telephone has an Attendant
Console associated with it, the bridged extension functions for the
telephone extend to the Attendant Console. For example, you can
configure an 3Com 2101 Basic Telephone with an associated Attendant
Console as a primary telephone with up to 11 bridged extensions on
Attendant Console buttons.
You can configure bridged extensions on the same buttons that are used
for the telephone's extension or on non-extension buttons. Before you
can create a bridged extension on a telephone, unlock the button
settings for the telephone group to which the telephone belongs (click
Telephone Configuration > Telephone Groups, select a group and then
click the Button Mapping tab).
You can view a report that lists the primary and secondary telephones on
which you have defined bridged extensions. See
