Surf Offering for LI MarketSurf Offering for LI Market

2-Wire Active/Passive Interceptor

PSTN (4-Wire) Interception SW module for Modem and Fax transmission

ISDN Framing Interception SW module

Mobile Interception (GSM) SW module for Data and Fax transmission

IP Interception SW module


2-Wire Active/Passive Interceptor2-Wire Active/Passive Interceptor

PCI card installed in a PC® between client side and CO

Built from Probing module, CO/Clients modules

The Interceptor “listens” to the 2-wire line

Continuously delivers the samples/Modem data to the host application

On/Off-hook detection

The Interceptor has four RJ-11 POTS

Record two separate calls simultaneously
