- Two independent IEEE C37.94 fiber optical connections over a single E1
- Standards compliant for power substation installations
- 19″ mounting with only 200mm depth
- Single power supply range from 48VDC to 230VAC
21-219 is an electro optical multiplexer between one G.703/704 E1 and two IEEE C37.94 optical ports. The two IEEE ports are fully mapped into G.704 standard frame structure of the E1 port, allowing for further SDH/ PDH multiplexing and de-multiplexing.
21-219 derives it synchronization from the network port (E1) or from an internal 2048Kbps PDH compliant clock enabling it to be used in leased line applications using electrical E1 modems such as SHDSL and alike.
