Prestige 201 ISDN Access Router
IP Subnet Mask - An IP address consists of two parts, the network ID and the host ID. The IP Subnet Mask
is used to specify the network ID portion of the address, expressed in dotted decimal notation. The Prestige
automatically calculates this mask based on the IP address that you assign. Unless you have a special need
for subnetting, use the default mask as calculated by the Prestige.
Syntax Conventions
"Enter" means for you to type one or more characters and press the carriage return. "Select" or
"Choose" means for you to select one from the predefined choices.
The SMT menu titles and labels are in Bold Times font. The choices of a menu item are in Bold Arial
font. A single keystroke is in Arial font and enclosed in square brackets, for instance, [ENTER] means
the Enter, or carriage return, key; [ESC] means the Escape key.
For brevity's sake, we will use "e.g." as a shorthand for "for instance", and "i.e." as a shorthand for "that
is" or "in other words" throughout this manual.
The Prestige 201 may also be referred to as the Prestige or the P201 from now on, in this manual.
