PLANNING

Determine for each

Station Group:

Call locationsLocal
Interlata (In state toll)
Interstate Toll
International Toll
Allowed call typesDDD
Operator assisted
Toll Free
Service Codes
Allowed call timesMaximum of 8 periods are available
Allowed facilitiesLocal CO trunks
Foreign Exchange (FX)
Wide Area Telephone Service (WATS)
Tie Trunk/International Voice Gateway
Note for each station the TGAR and NCOS if programmed


Determine for each

Trunk group:

Dialing patternsThe number of digits required to complete and identify each call type
Mandatory digits (is 1 required for a toll call?)
Preferred usage sequenceWhich trunk group will carry each call type at the lowest possible cost?
The second lowest cost? The most expensive?
PermissionsNote the TGAR for each trunk group


Select

System Wide

parameters:

Use the above information to determine the minimum of each parameter, then increase it by at least 10% above expected growth estimates. Max.# of location codes (ISDN networking)
Max.# of Supplemental Digit Restriction Blocks
Max.# of incoming trunk group exclusion tables
Max.# of Digit Manipulation Tables
Max.# of Route Lists
Max.# of Free Calling Area Screening Tables
Max.# of Free Special Number Screening Tables
Max.# of Special Common Carrier entries
Select these options based upon local needs BARS access code
Will second dial tone be provided?
Will expensive route warning tone be provided?
Will trunk group access restrictions be checked?
Will Off-hook or call back queuing be used?

There are no "wild card" characters, but limited ranging is permitted.

It is suggested that things will be easier in the long run if you define all 800 possible area codes, even though they are not as yet all in service.

This will use a trunk if an invalid number is dialed until the PTT rejects the call. This traffic increase should be insignificant.
