It is plugged in between the city phone line and the mini-ATX, providing secure
communications for all telephone sets and fax machines connected to the mini-ATX;
It has proved to be very useful for the construction of secure communication networks
with office PBX of any type;
Remotely controlled from the user's phone or fax machine;

"GROT" scrambler
Fully compatible with all previous versions of the SCR-M1.2 series;
Can be used to secure the whole path between the subscribers (co-operating with any
other SCR-M1.2 series scrambler), or to protect the subscriber's end of the phone path,
working together with the "Grot-C";
Enhanced cryptographic protection may be provided if additional master-keys are
installed at the customer's request;
An additional individual 7-digit code may be entered;
A simpler algorithm of input of individual keys-identifiers due to the presence of a
scratchpad for the individual keys;
A secure local telephone network, inaccessible for other scrambler users, may be created;
Extended voice support for operating modes: voice support for individual keys entered
directly or from the scratchpad;
Nonvolatile memory of individual keys-identifiers;
Delay time due to voice signal processing is reduced by half;
Ability to work in lines equipped with multiplexing systems and used for a security alarm;
A higher level of echo cancellation;
A reduced level of noise in the handset;
An improved quality of reconstructed speech;
