General:
A maximum of 48 pooled groups are allowed per system. Each
¥
pooled group corresponds to a Trunk Group number (1~32) or a
Route Advance Block number (1~16).
Pooled Line LED indicates the status of the pooled group as follows:
¥
On: All trunks in the pooled group are in use.
Off: Some or all trunks in the pooled group are idle.
When an idle Pooled line key is pressed, an idle trunk belonging to
¥
that pooled group is automatically selected. When the Electra Elite
48/192 system is designated as KF registration, this feature is not
available.
A user on a Pooled Line can access Call Park - System, Call
¥
Transfer, and Conference.
Trunk Queuing can be set when the Pooled line key is busy (red
¥
LED).
When a trunk is selected from Pooled line key, it appears on a CO
¥
line key or on a Call Appearance (CAP) key on the Multiline Terminal.
