The devices of this family have different mechanic designs: SubRack – a unit to be inserted into
a 19’’ FlexGain shelf; MiniRack – a 1U (44.5 mm) unit to be inserted into a 19’’ cabinet; Stand
Alone – a desktop unit; IP-67 – a unit in a water-proof plastic or silumin housing (class IP-67);
XCVR – a unit to be inserted into a hermetic steel housing.
The devices have the following possibilities for monitoring and management:
• Local management and control of remote devices and regenerators – VT 100;
•
Local management and control of remote devices and regenerators – Telnet session;
•
Operation in complex networks under the unified management system – support of SNMP.
The use of the Flash memory as the ROM provides an easy upgrade of the software.
xDSL modems are powered from a grounded primary DC source (38 … 78 V) or remotely.
Modems are designed to be used in-doors under the following environmental conditions:
- temperature of ambient air – from -5 … +45°C;
- relative air humidity – from 5% … 85% at +25°C.
