Call progress, modem handshake & protocol analyser for V.22bis dial-up systems
LineScope enables non-intrusive monitoring of modem communications
over the telephone line. LineScope is aimed at V.22bis modem integrators,
dial-up POS application developers and telephony gateway engineers.
LineScope is ideal for troubleshooting new deployments of terminals,
modems, transaction gateways (NACs), VoIP gateways and telephony
providers. Users in the payment terminal sector will appreciate the
built-in support for Fast-Connect, SDLC/HDLC and ISO-8583.
Obtain unique insight into physical layer issues, with tone event logging,
spectrogram & constellation displays, and effortlessly decode
POS SDLC and ISO-8583 financial message data.
