CO lines Allow/Deny Restriction Rules
• If there are no entries, no restriction is provided by the table.
• If there are entries in the Deny table, then the restriction is on a Deny Only basis.
• If there are entries in the Allow table, then the restriction is on an Allow Only basis.
• If there are entries in both the Allow and Deny Tables, the Allow Table is searched first. If a
dialed number matches an entry in the Allow Table, the call is allowed. If a match is not
found, then the Deny Table is searched. If a match is found in the Deny Table, the number
is restricted. If no match is found in either table, the number is allowed.
General Rules
• PBX Access Codes: There are five (2-digit) PBX access codes that allow you to enter the
system and access a CO line via PBX. A CO line marked as a PBX line will not be
controlled by any station or CO line COS until a recognized PBX code is dialed.
• Canned Restrictions: Canned, Restricted 1: Long distance call is not allowed. Canned,
Restricted 2: Long distance call is not allowed. Max. 8 digits (*, 0, # can not be dialed).
• Exception Tables A and B: These are the two exception tables for COS. Each table has 20
"allow" codes and 10 "deny" codes. Each code may have eight entries.
• CO Call Toll Checks: If an incoming CO Call Toll Check is set, the COS rule is applied
when the station dials after answering an incoming CO call.
