Technical data

The following equipment in the package:

"Grot" scramblers (installed at the subscribers');

"Grot-C" station scramblers;

MAK-16 station module for installation of 16 "Grot-C" scramblers with power supplies.

"Grot" and "Grot-C" scramblers, working together, provide cryptographic protection

for the section of communication lines between the subscriber and an automatic telephone

exchange (ATX).

When the user wants to switch into the secure mode, all he has to do is press the

button on the subscriber's scrambler, and the station unit will switch into the secure

communications mode automatically. There is a randomly selected session key generated for

every session, and besides, each pair of scramblers has 7-digit master keys. If any other SCR-

M1.2-series scrambler is present on the other side of the communication line, the station

scrambler may be switched in the "bypass" mode, and in this mode the whole path between

the subscribers becomes secure.
