Developed to combine performance, quality, and scalability, the Tahoe DSLAM takes advantage of the latest G.SHDSL technology to help operators address customers’ needs for greater bandwidth.

The Tahoe DSLAM is a 19” rack-mountable, 3U high unit designed to gather multiple G.SHDSL+ modems in one space saving case. It can hold up to 8 Tahoe 4681 cards containing 4 modems, each giving a total capacity of 32 G.SHDSL+ lines. Each line is capable of working either individually or as part of 4, 6 or 8-wire trunks.
