Planning Form Instructions

1.Use the following guidelines to determine which trunks to group into pools:

■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 and outbound-only trunks within the same 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. For private network systems, refer to the Network Reference for additional information.

2.Indicate the dial-out code in the Pool/Dial-Out Code column on Form 2c by doing one of the following:

■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.

b.On Form 2d, System Numbering: Special Renumbers, write the new number in the Renumber to column of the Pools section of the form.

3.On Form 2c, use the Function column to identify different calling areas of WATS trunks and different destinations of FX trunks.
