S E1 waveforms include G.703 waveshapes for both 75: coax and 120: twisted cables
S Analog loss-of-signal detection
S AIS generation independent of loopbacks
S Alternating ones and zeros generation
S Receiver power-down
S Transmitter power-down
S Transmit outputs and receive inputs present a high impedance to the line when no power is applied,
S Transmitter short-circuit limiter with current-limit-exceeded indication
S Transmit open-circuit-detected indication
S Backplane clocks output frequencies include 2.048MHz, 4.096MHz, 8.192MHz, and 16.384MHz
S CLKO output clock selectable from a wide range of frequencies referenced to MCLK
S 32-bit or 128-bit crystal-less jitter attenuator
S Requires only a 1.544MHz or 2.048MHz master clock or multiple thereof, for both E1 and T1 operation
S Can be placed in either the receive or transmit path or disabled
S Limit trip indication
