• A failure to match any Search Table Code or a fifth digit dialled without a match will
result in reorder being returned to the subscriber side.
• An FBC can have multiple PABX/Centrex codes of differing lengths, but none longer
than 5 digits.
• If the FBC is installed behind a PABX or on a Centrex line, these tables must be
enabled by Register 126 and programmed to distinguish between PABX/Centrex
extension numbers and trunk access code digits.

destination buffer; return dial tone to subscriber side; restart screening in the Primary
Search Tables (801-825)
Do nothing (wait for more digits)

• The normal way of using the PABX/Centrex tables is as follows: enter each PABX/
Centrex code followed by a #6. Use the #7 Action Code with incomplete code screens
in the "shorter" tables. The following examples illustrate these rules.
• For this example you should assume one valid PABX/Centrex trunk Access Code
which will be 0. Any call in which 0 is dial1ed as the first digit is considered an out-
side trunk call. If any other digit is the first digit dialled, the call is considered an
inside PABX/Centrex call. Register 126 should be set to a 1. The ACS (6r5) should
also be set to dial a 0.

• For this example you should assume one valid PABX/Centrex trunk Access Code
which will be 921. Register 126 should be set to a 1. The ACS (6r5) should also be
set to dial 921.

• For this example you should assume two valid PABX/Centrex trunk Access Codes
which will be 76 and 785. The ACS (6r5) should be set to dial 76 or 785, and Register
126 should be set to a 1.

The Select Digits Buffers are three temporary storage areas where subscriber-entered
digits can be moved. The digits are moved by use of either a select route or an action
code in the search tables. When a route is "selected" or an Action Code containing a
"move digits to select digits buffer" is executed, all the digits currently in the destination
buffer are moved to the select digits buffer for the search table currently in use. Digits
can only be moved to a specific select digits buffer once during a call, any additional
attempts to move digits will be ignored. The digits in the select digits buffers can be
output to the network by the "#06," "#07" or "#08" ACS tokens.
