For each of the 12 routes (six for each subpattern), you can specify a Facility Restriction Level (FRL). The FRL is used to refine the route selection process still further. Each route is assigned an FRL from 0 through 6 (6 is the most restricted). Each telephone is also assigned an FRL from 0 through 6 (0 is the most restricted). Callers (extension or remote access barrier code/trunk) can use the route only if their FRL is equal to or greater than that specified for the route. You assign a value of 0 to the route if you want all users to access the route, or 1 through 6 to restrict calling for the route to specific users only.

The form for a typical Area Code Table, illustrated in Figure 4–4, shows a table to route calls to the 13 area codes served by the northeastern (band 1) WATS lines beginning at 8 a.m. with no restrictions. The number of the northeastern WATS pool, 891, is on the first line in the Subpattern A section. The time, 8:00 a.m., is in the Time of Day space, and an FRL of 0 indicates no restrictions. The 11 p.m. in the Time of Day space for Subpattern B and Pool 70 in the Pool column indicates that calls to these area codes are to be routed over the main pool after 11 p.m.

Planning Form Instructions

In the Subpattern sections on Form 3f and Form 3g:

1.To direct calls differently according to time of day, write a starting time for each subpattern in the Time of Day space (for example, 8 a.m.).

2.To complete the Pool column for each subpattern, write the number of the preferred trunk pool next to the number 1. This is the pool to which calls to the area codes or exchanges listed in the Area Code/Exchanges section of this form should be directed.

If you want to designate a backup pool in case all the lines/trunks in the first choice pool are busy, write the number of the backup trunk pool next to the number 2, and so on.

3.To complete the FRL column, enter a value of 0 through 6. Assign a value of 0 if you want all users to access the route, or 1 through 6 to restrict calling for the route to specific users only. For all except the Default Local Table, the factory setting is 3. The Default Local Table factory setting is 2.

4.If extra digits at the beginning of the dialed number may be required for the system to place a call on a particular pool, enter the digits (0 through 9) in the same row as the pool number, in the column under the Other Digits heading. (See the Other Digits example below, in Figure 4–5.)

These special access or account codes can range from a single digit, such as 9, to a maximum of 20 digits.

Because calls to the 15 area codes shown on Figure 4–4 should be placed on the cross-country WATS lines/trunks when all the northeastern WATS lines/trunks are busy, the number of the cross-country WATS pool, 890, is used in both cases. An FRL of 4 is assigned to restrict some users from using cross-country WATS lines/trunks.
