G.703 Interface Nx64 Interface (Customer-sdie) (Customer-side) SHDSL Interface (Network-side) The Express 6530 can be powered from any AC power source ranging from 90 V to 240 V at frequencies of 50 Hz to 60 Hz, or a nominal -48 VDC E1 Framer power source. The SHDSL NTU will be used to provide access to Time slot customer premises to E1 or Nx64K leased-line Cross connect services, as well as primary-rate ISDN. The SHDSL (Service NTU is required to support leased-line G.703/G.704 Management) an
