Line and Fiber optic Modems
The VTLM is an Ikanos chip-set based SHDSL (Single Pair High Speed Digital Subscriber line) modem, used to transfer the data received on V.35/Ethernet over 2-wire / 4-wire copper infrastructure by applying standard SHDSL TC-PAM technology. This card supports quad-channel symmetric data rates from 72 Kbps to 5704 Kbps.
