[PoliKom]®-200U, the optical modem

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

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

The special features of this equipment are:

• low price;
• attractive mass-and-size indices;
• support VLAN (size of frame to 1916 bytes;
• the periodical of events before the energy-independent memory, which stores date, time and the nature of event;
• control according to joint RS-232 with the aid of the standard ANSI- terminal;
• the load of the new version of software based on the personal computer;
• mapping the current state by single indicators, notification about the emergency by sound signal;
• control capability besides the local and remote equipment;
• the small energy consumption (less than 3 W);
• the period of the guarantee of 5 years.

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

The optical modem Of [poliKom]®-200U 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 survey of the periodical of the occurred events on the local and remote equipment.

For facilitating the introduction of commands there is a program of control through the COM- port. Has graphic interface. It is compatible with the following operating systems: Windows of 98/ME/XP/2000.

The interfaces of equipment correspond to the standards [MSE]- T Of g.823, G.747, G.704, G.703, G.651, G.652, G.654.
