Planning Form Instructions
On Form 2c, for each line/trunk with All or an extension number in the QCC
Operator to Receive Calls column, write the priority level (1 to 7) in the QCC
Queue Priority Level column for each line/trunk used for incoming calls. (A value
of 1 indicates the highest priority; a value of 7 indicates the lowest. The factory-set
priority for calls received on all trunks programmed to ring in the queue is 4.)

Pools (Hybrid/PBX Mode Only)

The system can have up to 11 pools with factory-set dial-out codes of 70 and 890
through 899. When the system is set up, pools are assigned automatically (see
the Feature Reference ). If you want any lines/trunks grouped in a pool, you must
manually assign each line/trunk to the pool of your choice. Use the instructions in
this section.
Decide whether to change the dial-out codes. Apply the same considerations as
you do for reassigning extension numbers.
Planning Form Instructions
1. Use the following guidelines to determine which trunks to group into pools:
2. Indicate the dial-out code in the Pool/Dial-Out Code column on Form 2c by
doing one of the following:
Each pool should contain trunks of the same type (basic, WATS,
FX, or tie). Ground-start and loop-start trunks of the same type (for
example, WATS or FX) can be mixed in the same pool.
Do not mix different calling areas of WATS or FX trunks to different
cities or include both inbound-only or outbound-only trunks within a
pool. DID trunks and/or trunks used for auxiliary equipment cannot
be grouped in pools. T1 Switched 56 data lines should not be mixed
with trunks used for voice calls. If you plan to assign Pool buttons
on telephones, do not group dial-in-only tie trunks in pools.
In typical pooled systems, all the trunks are grouped in pools except
those mentioned previously, single special-purpose trunks, and any
basic trunks that are needed as personal lines assigned to a button
on a telephone.
Group the trunks for the main pool first. This should be the local
trunks capable of accepting 411, 911, and so on. If your system
includes ground-start basic trunks, reassign them from the dial-890
extension pool to the main pool. After these trunks are assigned to
the main pool, decide how to arrange the rest of the trunks in the
remaining pools.
To keep the factory set dial-out code, write the code.
To change the factory-set dial-out code:
a. Write the new number in the Renumber to column.
