QUAD T1/E1/J1 FRAMER/LIU COMBO - E1 REGISTER DESCRIPTION
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. The XRT86VL34 contains an integrated DS1/E1/J1 framer and LIU which provide DS1/E1/J1 framing and error accumulation in accordance with ANSI/ITU_T specifications. Each framer has its own framing synchronizer and transmit-receive slip buffers.
