Signaling Security Templates

Signaling Security templates define rules for calls screening based on the call's 
source/destination addresses.
A template holds the following information:
1

Name of template - up to 20 characters template name.

2

Source NSAP/Mask - A specific NSAP address or an address mask.

3

Destination NSAP/Mask - A specific NSAP address or an address mask.

4

The rule - deny or permit.

An address mask is an expression designed to define a set of addresses. A mask 
expression may include two wildcards characters '*' and '?' where '*' represents any 
address portion (i.e. any number of nibbles) and '?' represents a single nibble (half a 
byte).
Example: an address mask that is designed to match an ATM host having a MAC 
address of 11.22.33.44.55.66 (i.e. bytes 14-19are the MAC) would have the form of: 
*.11.22.33.44.55.66.??, where the '*' represents the ATM prefix, and the '??' represents 
the Selector.
Example: an address mask that is designed to match all the hosts having an address 
prefix 39.03.00.00.00.00.00.00.00.00.00.00.00 would have the form of 
39.03.00.00.00.00.00.00.00.00.00.00.00.*
Where the '*' represents all possible combinations for ESI + Selector.
