Virtual Receiver Architecture
The most novel feature of the DRL2E is its ability to
use the telephone company information delivered as
DNIS (Dialed Number Information Service) or Caller
ID. This allows the Sur-Gard Format Expert System to
handle on the fly each received call. With this feature,
dedicated line pool hardware is eliminated. Instead,
the DNIS or Caller ID information allows dynamic
options that set up virtual line pools to identify secu-
rity formats and extend account numbers.
Standard DNIS is supported up to 10 digits. Each
dialed number should be assigned to a virtual receiver.
Multiple Caller ID numbers can be assigned to a single
virtual receiver. Each dialed number would formerly
have been a line pool on conventional line cards.
1.7
Number of Line Cards Supported
The system will support a maximum of 15 line card
modules concurrently connected.
