ABSRTACT:
The present manuscript deals with the conversion of 256P RAX to AN-RAX and also the installation procedure of 256P RAX to AN-RAX. The 256P RAX uses only 184 lines PSTN subscribers but if we convert it into ANRAX it uses 248 lines PSTN subscribers through V5.2 protocol. The 256P RAX consists of three racks, they are: 1) Power Distribution Panel (PDP), 2)Master Frame & 3)Slave Frame. After the conversion of 256P RAX to AN-RAX we can use the master frame as slave frame and slave frame as master frame, both will be same after the conversion. To do the conversion of 256P RAX some of the cards become redundant and those cards have to be removed. Then the modification will be done for the 256P RAX. The conversion and installation procedure is completely done in five steps. The main objective for converting the 256P RAX we can have the maximum lines for the exchange.

I. INTRODUCTION:
The ‘C-DOT Access Network - Rax’ (AN-RAX) will provide the second level of remoting. AN-RAX might be connected to a RSU or directly to the Local Exchange (LE). The AN-RAX supports V 5.2 protocol, and handles the functionality of second level of remoting.
The second level of remoting has its scope and role clearly defined. At this level there would neither be any intra switching or call processing activities, nor the AN-RAX would handle the charging, billing and administration functions of subscribers.
AN-RAX provides a
