[PoliKom]®-741M, the device of the access Of [e]1.

Producer: Joint stock company of Research and Production Enterprise the range

Equipment Of [poliKom]®-741M is intended for the transfer of asynchronous flow RS-232 before the structure of frame E1. For the transfer RS-232 will begin to operate one time- slot Of [e]1 (speed to 19 200 [bit]/c).

The complex of the articles Of [poliKom]®-741M makes it possible to effectively organize centralized control besides the remote devices through the sequential asynchronous port by means of the telecommunication flows Of [e]1.

Equipment Of [poliKom]®-741M can be used for:

centralized control besides the remote equipment through the interface RS-232;
the organization of channel RS-232 for the data collection about rate setting of connections based on remote ATS;
the connection of the remote devices for the sake of the sequential interface;
the connection of the remote computer to the local network.

For the installation of article beside the standard counter (cabinet) is provided special shelf - regiment beside counters 19 " for the housing Of g706.

[PoliKom]®-741M, the device of the access Of [e]1.

The special features of this equipment are:

control according to joint RS-232 with the aid of the standard ANSI- terminal;
the program tuning of the begun to operate time- slots;
the periodical of events before the energy-independent memory, which stores date, time and the nature of event;
the stable operation in the absence of the input signal Of [e]1 on the station port;
with the nonconformity of the input signal of the recommendation Of g.704 (including LOS, AIS) the equipment ensures its forming against the linear joint;
the program tuning of the parameters RS-232 and E1, including the installation of trains;
mapping the current state by single indicators;
notification about the emergency by sound signal;
attractive mass-and-size indices;
control capability besides the local and remote equipment by means of S of bits before the structure of the signal Of [e]1;
the small energy consumption (less than 1 W);
the period of the guarantee of 5 years.

Diagram of the start

Control besides equipment is accomplished on the joint F (RS-232) with the use of any standard ANSI - terminal.

[PoliKom]®-741M allows wide control capabilities with the aid of PK:

monitoring the local and remote equipment before the regime of real time;
the reconfiguration of the local and remote equipment (including the installation of trains);
the installation of the utilized time- slots;
the installation of the code before the line Of [e]1 (HDB-3 or AMI).
