6. EXAMPLES
5.15 If an extension dials a CO code of 555, the system will recog-
nize that call as a call for directory assistance. If 555 is defined
as a CO code in the local Area Code, it will go out on a local trunk If
the CO code is not defined for an area code, 555 calls are given the
411 route. It is important then to assign the 411 service code a
particular route.
6.01 This Part will outline four specific examples. Each case will
assume digits are dialed from an extension at a system
(SX-lOO/SX-200) and listed as 592-2122. Each Trunk Group used with-
in a particular Route Table may require digit insertion and/or deletion
to obtain the proper route.
(a) EXAMPLE 1: The caller dials the ARS access code (assumed as
digit 7) followed by the required telephone number; i.e.,
Area code 315 selects Route Table 2 (Figure 6-3) and CO trunk
resulting in the outpulsed digits on Rl as:
(b) EXAMPLE 2: The caller dials the ARS access code and the
telephone number as follows:
Area code 419 selects Route Table 3. Tie trunk R3 is the first
choice and the CO trunk access code of the associated System
(in the "419" area) is "95". The Modify Table deletes area code
digits "419" and adds digits "95". The outpulsed digits over the
Tie trunk R3 are thus:
(c) EXAMPLE 3: This call is one made to CO code "632' in Area
This combination of Area and CO Code digits selects Route
Table 4 (Figure 6-3) with Tie trunk R4 as first choice (Table
6-l(d)). The CO trunk access code digits "96" are added and the
area code digits "315" are deleted. The resulting outpulsed dig-
its over trunk R4 are:
( d ) EXAMPLE 4: The same call is attempted as in Example 3, but it
is assumed that Tie trunk R4 is busy and the call is to be routed
via Tie trunks R3 and R6. The outpulsed digits must be different
to accommodate the accessing, by trunk R3, of trunk R6 (access
code "81"). The outpulsed digits over the Tie trunk R3 will be as
follows:
