Trunk Groups may be assigned a preference of 1 to 4 per time period
(schedule). The same Trunk Groups may be assigned different pref-
erences in different time periods (Schedules).
5.08 For example, consider three Trunk Groups:
Trunk Group 1 is composed of Tie trunks.
l
Trunk Group 2 is composed of WATS trunks.
Trunk Group 3 is composed of DDD (Direct Distance Dialing)
Trunks.
In Schedule A (08:00-17:00),
Trunk Group 2 is assigned preference 2 and Trunk Group 3 is not
assigned a preference. In Schedule B (17:00-23:00),
retains preference 1, Trunk Group 3 is assigned preference 2 and Trunk
is
Group 2 assigned preference 3. In Schedule C (the remaining time),
Trunk Group 1 is given preference 1, Trunk Group 3 is assigned pref-
erence 2 and Trunk Group 2 is not assigned. Note that a fourth
preference was not used in this example.
Schedules A, B and C
5.09 There are three time Schedules (A, B and C) based upon a
24-hour day. Schedule A will originally appear as assigned to
the entire 24-hour period. Schedule A may be programmed to any time
period in the 24-hour day. Schedule B may not be programmed if
desired. Any time period not programmed to Schedule A or B will
default to Schedule C. Schedules A, B and C must start and stop on the
hour; minutes may not be programmed. These Schedules (A, B and C)
allow Basic Schedule Data to be subject to a maximum of three time
in
periods, which each time period may change the order of preference
in the Basic Schedule Data. In other words, route choice preference
may change in order of time Schedules A, B and C. Schedules A, B and
C are entered as beginning hours and ending hours. For example, if the
beginning hour is 08:OO and the ending hour is 17:00, the entry must
be made as 0817. For a brief overview of paragraphs 5.04-5.09, consult
Figure 5-1.
5.10
Any 3-digit code which appears in the Area Code Table may be
programmed as a service code by assigning it Route Table 0.
Thus, codes such as 411, 611 and 917 may be labeled as service
codes.
5.11
The Route Table used for the service call is chosen in exactly
the same way as with any other local call. This is done by using
411 as an office code in programming an Office Code Table. Hence, if
the local area code is 613, programming 411 as an office code in a
table tied to 613 causes the system to use the. associated route table
specified (Figure 5-2). Upon a user dialing 411, the system finds that
411 is a service code and uses 613 as the area code to search for a
Route Table to use (Figure 5-3).
