PolyKom-741M is designed for transmission of an asynchronous data stream RS-232 in the structure of E1 frame.
For RS-232 transmission is used one E1 time-slot (speed is up to 19 200 bits/c).
There is a special mounting for 19'' rack to install the unit in a standard rack (box).
PolyKom-741M can be used for:
- centralized management of the remote equipment through the RS-232 interface;
- arrangement of RS-232 channel to collect data on the billing of connections from remote PBX;
- connection of the remote devices with serial interface;
- connecting of remote computer to a local network.
Polycom-741M complex can effectively organize the centralized management of remote devices via the serial asynchronous port by means of telecommunications E1 streams.
Features of this equipment:
- management via RS-232 joint using the standard ANSI-terminal;
- software setup of utilized time-slots.
- event log in the nonvolatile memory, which stores the date, time and nature of the event;
- steady work when there is no input E1 signal at the station port;
- at discrepancy of the input signal of G.704 recommendation (including LOS, AIS) the unit provides its shaping on the linear joint;
- software configuration of RS-232/RS-485 and E1 parameters, including the installation of loops;
- display the current status by single indicators;
- notification about the emergency by sound signal;
- attractive dimensions and weight;
- control over the local and remote equipment by means of S-bits in the structure of E1 signal;
- low power consumption (less than 1 W);
- 5 years warranty.
Equipment control is performed via F joint (RS-232) using any of the standard ANSI - terminal.
PolyKom-741M provides ample opportunities of management with the help of a PC:
- monitoring of local and remote equipment in real time;
- reconfiguration of local and remote equipment (including the loopbacks installation);
- installation of utilised time-slots.
- code setting in the E1 line (HDB-3 or AMI).
Equipment Interfaces compliant with ITU-T G.704, G.823 recommendation.
