  The X25router 2000 software requires the DEC MicroServer (DEMSA) or DEC      
  MicroServer-SP (DEMSB) hardware unit, available as follows:

  The DEC MicroServer and DEC MicroServer-SP have a built-in LAN controller,   
  however, a suitable connection to connect to the customer's LAN is           
  necessary, together with any necessary extension cables.                     
                                                                               
  The DEC MicroServer and DEC MicroServer-SP use adapter cables to provide     
  the necessary interchange circuits at the appropriate electrical interface   
  types and ISO standard connections for each synchronous line. A cable  is    
  needed for each line used. The following table shows the cable numbers for   
  each of the electrical interface types. Note that the MicroServer-SP is      
  provided with a V.28/V.24 cable as standard.
