AM64/128

The AM64/128 is a modular system of desktop and rackmount baseband modems that provide high quality transmission over standard copper pairs. Diagnostic loops allow easy location of faults in access network cabling.

AM64/128A

Product Overview

The AM64/128 is used to provide reliable high speed transmission links over copper. The transmission system, originally designed and developed by ATL for BT’s kiloStream network is used to transmit the data.

Where variable rate interfaces are used at both ends, such as V.35 or X.21, rate adaption allows the units to automatically find the maximum operating data rate for a given line.

Typically, the modems are used to provide leased line circuits over rented copper pairs (e.g. in the UK, BT EPS9 baseband circuits.)
