line marked as a PBX line will not be governed by any station or CO line COS until a recognized PBX
code is dialed.

Exception Table A & B
There are two exception tables with COS. Each table has 20 allow codes and 10 deny codes and a
code may have eight entries.
Condition
1. Rule of COS
- In STA COS 7, no dialing is allowed to CO line.
- In CO COS 5, STA COS 1~6 is ignored and there is no restriction to access CO line.
- In CO COS 4, STA COS 1~6 is ignored. The long distance call is not allowed and max. 8 digits
may be dialed.
- In CO COS 1, it is restricted by STA COS.
- In CO COS 2 and STA COS 2/4, it is restricted by Exception Table A. There is no restriction in
STA COS 1/3. In STA COS 5, long distance call is not allowed and max. 8 digits can be dialed.
2. Rule of CO line Allow/Deny Restriction
- If there is no entries, no restriction is provided by the table.
- If there are entries in the Deny table, then restriction is on a 'Deny Only' basis.
- If there are entries in the Allow table, then restriction is on a 'Allow Only' basis.
- If there are entries in both the Allow and Deny Tables, the Allow Table is searched, if the dialed
number matches an entry in the Allow Table, the call is allowed. If a match is not found the Deny
Table is searched and, if a match is found in the Deny Table, the number is restricted otherwise,
the number is allowed.
3. General Conditions
If ‘Incoming CO Call Toll Check’ is set, the COS rule is applied when the station dials digits after
answering the incoming CO call.
