450 Expansion Module for IP Phone 1100 Series

administered configuration. When a second Expansion Module is detected,

the TPS changes the key assignments to display across both Expansion

Modules.

If two Expansion Modules are configured in LD 11 but three Expansion

Module respond, the TPS assigns the keys 32 to 67 to the first two

Expansion Modules. The third Expansion Module does not have keys

assigned until it is configured in LD 11. An error message displays to

alert the administrator that the hardware configuration does not match the

administered configuration.

If three Expansion Modules are configured but only one Expansion Module

responds, the TPS assigns the keys 32 to 67 to the single Expansion

Module (using the Shift key functionality). When a second Expansion

Module is detected, the TPS changes the key assignments to display

across both Expansion Modules. Keys on the third Expansion Module are

unaccessible.

If three Expansion Modules are configured in LD 11 but two Expansion

Modules respond, the TPS assigns keys 32 to 85 to the first two

Expansion Modules. An error message displays to alert the administrator

that the hardware configuration does not match the administered

configuration. When a third Expansion Module is detected, the TPS

changes the key assignments to display across all three Expansion

Modules.

Services key operation

The Services key is used to access user settings and certain features

on the IP Phone. When one or more Expansion Modules are attached

to the IP Phone, the actions of the display diagnostics for the IP Phones

DN/feature key display area are duplicated for the Expansion Modules.

If an incoming call occurs when in the diagnostic mode, the call is

answered by pressing the DN/feature key, handsfree, or headset key, or

by picking up the handset. The display area remains in diagnostic mode

until either the user exits the diagnostic more, or the idle timeout clears

the mode. Once cleared, the normal display for the current state of the IP

Phone is displayed.

Press the Services key to access the following menu items
