1.8 LNA-6: Lin e Am p lifie r Mo d u le , Le a s e d Lin e
The LNA-6 line amplifier module provides a matched leased line interface for up to six (6) leased
circuits from a single modem. Modems with speeds up to 2400 bps may be connected via the VF
circuit interface that is bussed to the backplane connector.
There are six (6) RJ12 sockets on the front panel for connection to leased circuits. The module
provides galvanic isolation and surge protection from the line to the equipment side and signal voltage
limiting, line matching from the equipment side to the line side.
This module must be located within a BAX-6 backplane and cannot be fitted or mixed with standard
Kingfisher PLUS+ modules.
