HAPTER EVICE ONFIGURATION
Provided that you do not exceed the limits shown in Table 25, you can
configure the maximum number of bridged extensions using any
combination of primary telephones and bridged extensions. For example,
on a SuperStack 3 NBX 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, one of the secondary telephones can
be configured 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 of the calls.
You can configure as few as one bridged extension on a telephone, or as
many as 11. The maximum number derives from the fact that an NBX
1102 or 2102 Business Telephone, which has 12 buttons, can be a
secondary telephone, and each secondary telephone must have at least
one button reserved for its own extension.
If a secondary telephone has an 1105 Attendant Console associated with
it, there can be bridged extension buttons on the Attendant Console for
more than one primary telephone, but no more than 11 buttons per
primary telephone.
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, an NBX Basic
Telephone with an associated Attendant Console, can be configured 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 (by default, buttons 1, 2 and 3 on an
NBX 1102 or 2102 Business Telephone) or on non-extension buttons.
Before you can create a bridged extension on a telephone, you must
unlock the button settings in the telephone group button mappings
dialog box for the telephone group to which the telephone belongs.
You can view a report that lists the primary and secondary telephones on
which bridged extensions have been defined. See "Viewing
Bridged Extension Information" on page 142.
