If you've never set up TRS in any Panasonic system, you're in for a treat :-)
There are 5 classes of service in a TA-824. Think of it this way. COS 1 is unrestricted, then 2-5 are various levels of restriction. In theory, you could restrict 80 code sequences. In practice, you'll probably use about 10. The best way to understand the process is to load the maintenance console, click on TRS, click on help, and click on 1.1.117 in the Feature Guide. It gives you a visual picture of how TRS works.
A fast example, put 911, 1800,1888 etc in allow 5. Now go to COS 3 and put 1 and 0 in Deny. When you set your ext COS to 3, you can only dial toll free numbers and 911. Now go to COS 2 and put in 1900 in Deny. Now if you change the ext to COS 2, you can dial anything but 1900.
You use COS 2 to prohibit stupid area codes like 900, 806 or whatever the Carribean code is, 976 numbers, and 011 international calls.
Just remember that the tables are floating. COS 2 is the most permissive and COS 5 is the most restrictive.
