1. DETAILED DESCRIPTION
The DS21349 is a complete T1 line interface unit (LIU) for short-haul and long-haul applications.
Receive sensitivity adjusts automatically to the incoming signal and can be limited to -18dB, -26dB, or
-36dB. The device can generate the necessary DSX-1 line build-outs or CSU line build-outs of 0dB,
-7.5dB, -15dB, and -22.5dB. The on-board crystal-less jitter attenuator requires a 1.544MHz reference
clock. The jitter attenuator FIFO is selectable to either 32 bits or 128 bits in depth and can be placed in
either the transmit or receive data paths. The DS21349 has diagnostic capabilities such as loopbacks and
QRSS pattern generation and detection. The device can also generate and detect the in-band loop-up and
loop-down codes specified in AT&T 62411. The device can be configured for control using a serial
interface, or for hardware mode. The device fully meets all of the latest T1 specifications including ANSI
T1.102-1999, ANSI T1.403-1999, ANSI T1.408, and AT&T 62411.
