MUX128K - Inverse Multiplexer for G.703 64 Kbit/s

1245483

2*64kbit/s Inverse Multiplexer for G.703 to X.21

Description:

The MUX128 is used to multiplexe two 64 kbit/s G.703 - channels to one 128 Kbit/s channel. The device uses no overhead for syncronisation and provides the full bandwith (128 Kbit/s at the interface.

The interface at the device is supplied as RS530, other interfaces (X.21) also possible wit adapter- cable
