10 Channel Digital UHF Radio

10  Channel  Digital  UHF  Radio  (6RU10)  is  a low capacity digital radio transmission system. It  operates  innbsp; the UHF band of   frequencies   ranging   from   622   to 712MHz.  The   system   can   be   used  to establish  a  highly reliable point  to  point communication  link-up  to  a  distance   of 50Km   in   a   single   hop   (for   example connecting RAX and MAX)

Inputs  to  this  system  are  six wire (or four wire) analog voice channels. The system can cater to ten such channels. These analog voice channels are digitized  into  64  Kbps PCM format and multiplexed to obtain 704 Kbps digital stream. This signal is frequency  modualted  and transmitted in the UHF bank.

In  camparison  with  open  wire  system,  this is very cost-effective and possesses definite operational advantages which are as under:

System  maintenance  is  easier  compared  to that of open wire or  cable systems. This is because  of  the fact that fault is inherently localised at one of the two ends of the link. This obviates the necessity to move along the route in search of fault location.

Built-in  Test Equipment  (BITE)  has  been  provided  for  ease of fault localisation.The out of serve system can be restored to healthy condition quickly by the replacement of plugin modules.
