• On power-up, all OE7:0 bits are cleared to ‘0’.
• When an OE bit is set to ‘1’, the output driver of its corresponding transmitter
LEN0-2 determine the operation mode of the LXT384 Transceiver: T1 or E1. In
addition, for T1 operation, LEN2-0 set the pulse shaping to meet the T1.102 pulse
template at the DSX-1 cross-connect point for various cable lengths:
