3am LineScope
Call progress, modem handshake and data analyzer for V.22bis dial-up systems

LineScope enables non-intrusive monitoring of synchronous and asynchronous communications over a telephone line. It's just the thing for V.22bis modem integrators and dial-up application developers. Engineers in the payment terminal sector will appreciate the built-in support for Fast-Connect, SDLC/HDLC and ISO-8583.

This product is ideal for troubleshooting new deployments of terminals, modems, transaction gateways (NACs), VoIP gateways and telephony providers. It can also be used for lawful interception and surveillance applications, as a dial-up modem sniffer, data line monitor, data-scope and QPSK/QAM analyzer. Legacy Bell-212A and Bell-224 are supported.

Diving even deeper than Ethereal/WireShark, LineScope takes the modem line tap approach to a whole new level. It provides unique insight into physical layer issues, with tone event logging, constellation displays, eye diagrams and raw bitstream views, as well as effortlessly decoding SDLC/HDLC and ISO-8383 financial messages.
