When the TNS machine arrives at your library, the phone matrix is set up so that calls to all area codes and prefixes are blocked. You need to modify the matrix to give the TNS PC instructions for dialling area codes and/or exchanges in your library’s service area. The Sample Call can be made without modifying the phone matrix.

1. First enter the area code details for all your patron telephone numbers in the TNS Matrix Worksheet. The matrix is stored in your TNS software but does not display, so be sure to keep a hard copy of your matrix worksheets.

   The area code is the first set of three digits in a telephone number, and the exchange is the second set of three digits., e.g.:

2. To modify the phone matrix, from the TNS Main Menu:

   	select 9. Utilities and press Enter
   	select 3. Modify Phone Matrix and press Enter to display the Dialing Normalization Matrix screen

   

   In the Dialing Normalization Matrix screen, the cursor highlight is in the Area Code field. To specify an Area Code number:
   

   	use the Page Up and Page Down keys on the PC's keyboard to set the hundreds digit
   	use the keyboard up and down arrow keys to set the ones and tens digits

   Specify an exchange number, for example you may want to restrict or block calls to specific exchanges in a certain area code:
   

   	use the right arrow key to move to cursor to the Exchange field
   	use the Page Up and Page Down keys on the PC's keyboard to set the hundreds digit
   	use the up and down arrow keys to set the ones and tens digits
   	to dial all exchanges in an area code, press the Page Down key until ANY displays instead of a number

   Edit instructions Add Prefix, Add Suffix, Remove AC, Block Call:
   

   	press the Shift e keys
   	add a Prefix if needed, eg. 1 for long distance calls. TNS is programmed to dial 9 to exit your library phone system so it is not necessary to add 9 as a prefix. Do not enter a space after the number. Press Enter
   	arrow key down to Add a Suffix if needed. Do not enter a space after the number. Press Enter
   	arrow key down to Remove AC (area code). Type Y to instruct TNS to call an Area Code. Type N to instruct TNS not to call an Area Code
   	arrow key down to Block call. Press N to unblock calls to the Area code. Press Y to block calls

   EXAMPLE 1: Local calls from area code 510. TELEPHONE field in patron record entered as 510-655-6200. TNS does not need to call the area code (AC) or all exchanges.

   

   EXAMPLE 2: Calls from area code 510. TELEPHONE field in patron record entered as 650-343-6829. TNS does need to call area code (AC).

   

3. Repeat for all area codes listed in your TNS Matrix Worksheet. When complete press q to quit back to the Utilities menu

4. To change settings for an area code at any time:

   	move the cursor highlight to the Area Code field
   	retrieve the area code number using the keyboard Page up, Page down and arrow keys
   	press Shift e to edit the instructions for the area code
   	press q to quit back to the Utilities menu

5. If you want to delete all area code entries and start again, use Reset Phone Matrix:

   	from the Utilities menu, select 2. Reset Phone Matrix
   	TNS prompts: Are you absolutely sure you want to run this program (y/n):
   	press n to return to the Utilities menu
   	press y and the system prompts: Allow long distance calls (y/n):
   	enter n and press Enter to block all area code calls
   	if you press yand enter, calls to all area codes are allowed
   	from the Utilities menu select 3. Modify Phone Matrix and specify instructions for area codes as shown above
