GENERAL DESCRIPTION
   The XRT86VL34 is a four-channel 1.544 Mbit/s or 2.048 Mbit/s DS1/E1/J1 framer and LIU integrated solution featuring R3 technology (Relayless, Reconfigurable, Redundancy). The physical interface is optimized with internal impedance, and with the patented pad structure, the XRT86VL34 provides protection from power failures and hot swapping.
