[PoliKom]®-200M, the optical modem

The special features of this equipment are:

• support VLAN (size of frame to 1760 bytes);
• the periodical of events before the energy-independent memory, which stores date, time and the nature of event;
• the filtration of Ethernet- traffic;
• control according to joint RS-232 with the aid of the standard ANSI- terminal;
• the built-in link between operators for the sake of the operator of the remote equipment (channel of oral communication);
• 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 and by means of the stand signaling (“dry contacts”);
• control capability besides the local and remote equipment;
• small energy consumption (to 4 W);
• the period of the guarantee of 5 years.

Control besides equipment is accomplished on the joint F (RS-232/USB 2.0) with the use of any standard ANSI - terminal.

The optical modem Of [poliKom]®-200M 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.

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

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.
