Toll Exception Tables
– Each Toll Exception Table permits entry of 50 Allow codes
and 50 Deny codes. Each code can contain up to 20 digits including digits 0-
9, “#”
as a wild card (any digit) and “*” as the end of entry mark (refer to Station Class of
Service table to determine application of Toll Exception).
Exception Table process
– As digits are dialed, they are compared to entries in the
appropriate Exception Table. Based on the Allow and Deny entries, the system
applies the following rules to allow or deny calls.
Rule 1
– If a table has no entries, no restrictions are applied.
Rule 2
– If there are only Deny entries, restrictions are provided as Deny only.
Rule 3
– If there are only Allow entries, restrictions are provided as Allow only.
Rule 4
– If there are both Allow and Deny entries, the Deny entries are
searched. If the dialed number matches a Deny entry, the call is restricted; if no
match is found the call is allowed.
