PolyKom-300

Do not use in new projects!
Polycom®-300 is designed for multiplexing of up to 16 E1 streams, Ethernet data and asynchronous data (RS-232/485, 115.2 Kbit/s), and their transmission to the distances of up to 110 km via one or two optic cables. PolyKom-300 supports one permanent module 4xЕ1, one permanent RS-232/485 port and three demountable Link modules.

channel module includes:

  • 4 E1 streams;
  • 10BASE-T Ethernet (8 448 Kbit/s);
  • Three channels of E1 + 10BASE-T Ethernet (2 048 Kbit/s).

With the help of these ports can be realized different combinations of the 3 Ethernet ports + 4хE1 and up to 16 E1 streams. 



Features of this equipment:

  • Filtering of Ethernet traffic (Ethernet-bridge);
  • possibility of control via PC;
  • control via SNMP on RS-232 or HTTP link (possibly via LAN or Internet);
  • ability to work on obsolete optic multimode fibers;
  • built-in intercom with the operator of remote equipment (voice communication channel);
  • log events in non-volatile memory, which stores the date, time and character of events;
  • display of a current state by single indicators, notification about the emergency by sound signal and by stand signaling("dry contacts");
  • low power consumption (less than 15 W);
  • control over the local and remote equipment.

Equipment control is performed on one of the two joints:

  • F joint (RS-232) with use of any of the standard ANSI - terminal;
  • Q joint 10/100BASE-T Ethernet via HTTP and SNMP v.1.0 protocols, with use of any Web browser or SNMP manager respectively.

Polycom-300 provides ample opportunities of management with the help of PC:

  • Monitor of local and remote equipment in the real-time mode;
  • configuration of the local and remote equipment (including cables installation);
  • view of the event log on the local and remote equipments.

Equipment interfaces compliant with standards ITU-T G.823, G.751, G.775, G.703.
