Description
Loop Mode 1. Iif driven high the loopback mode of channel 1 will be set to re-
mote loop. Otherwise the loopback mode will remain at local loop. The actual
loopback will be activated when the LOOPEN1 is asserted.
Receive V
Receiver 1 Negative Data Out. Negative data output in NRZ or RZ format for
receiver 1.
Receiver 1 Positive Data Out. Positive data output in NRZ or RZ format for
receiver 1.
Receiver 2 Negative Data Out. Negative data output in NRZ or RZ format for
receiver 2.
Receiver 2 Positive Data Out. Positive data output in NRZ or RZ format for
receiver 2.
Digital V
E1/T1- Selection. Apply logic one to select the receive data threshold appropri-
ate for E1 operation. Connect to ground to select the T1 data threshold.
Loop Enable 1. If driven high the specified loopback mode will be enabled for
channel 1. Otherwise normal operation will continue.
Loop Enable 2. If driven high the specified loopback mode will be enabled for
channel 2. Otherwise normal operation will continue.
Transmitter 1 Negative Data In. Negative data input in NRZ or RZ format for
transmitter 1.
Transmitter 1 Positive Data In. Positive data input in NRZ or RZ format for
transmitter 1.
Transmitter 1 Clock Input. Apply logic one when RZ signals are supplied to
data inputs.
Transmitter 2 Negative Data In. Negative data input in NRZ or RZ format for
transmitter 2.
Transmitter 2 Positive Data In. Positive data input in NRZ or RZ format for
transmitter 2.
Transmitter 2 Clock Input. Apply logic one when RZ signals are supplied to
data inputs.
Analog V
Loss of Signal Voltage Select. Apply logic one to select LOS voltage level
appropriate for 120 balanced receiver operation. Connect to ground to
choose LOS voltage for 75 unbalanced operation.
Transmitter 2 Output Enable. If asserted the transmitter 2 output drivers are
enabled. High-Z otherwise.
Transmitter 1 Output Enable. If asserted the transmitter 1 output drivers are
enabled. High-Z otherwise.
Transmitter 1 Output. Transmitter 1 bipolar output connected to coupling
capacitor or pulse transformer through a resistor.
