Digitel NTU Applications

Besides using the DT SHDSL C/S NTU in connection with the Alcatel Mainstreet 3600 the NTU can be used in many other applications without the Mainstreet.

All the applications however involve transmission over twisted copper pairs to provide digital transport for a variety of data formats and data rates. The mode is G.SHDSL. The distances that this Technology can span without repeaters are dependent on the data rate.

The NTUs standalone or rack-mount are configured as master or slave.

Except for private networks the master unit is usually located at the central office and is usually a rack-mount model.

The slave unit is usually a stand-alone model.

 

In the simplest application this NTU is used point to point as a leased lineG.SHSDL modem
