Line Interface Unit (LIU)

• T1 and E1 modes use the same 1:1 transmit and receive transformers

• Internal register allows termination impedance to be changed under software control.

• Programmable pulse shapes and pulse amplitudes

• Automatic or manual receiver equalization

• Receive signal peak amplitude is reported with 8-bit resolution

• Output pin to indicate Loss Of Signal/ Loss Of Frame synchronization

• LIU output is disabled at power-up until enabled by software

• Input pin to force transmission of AIS

T1/J1 Mode

• Reliably recovers signals with cable

attenuation up to 36 dB @ 772 kHz

• Transmit pulse meets T1.403 and T1.102

pulse templates

• Indicates analog Los Of Signal if the

received signal is more than 20 dB or 40 dB

below nominal for more than 1 ms

• Receiver tolerates jitter as required by AT&T

TR62411

E1 Mode

• Reliably recovers signals with cable

attenuation up to 40 dB @ 1024 kHz

• Transmit pulse meets G.703 pulse template

• Indicates analog Los Of Signal if the received

signal is more than 20 dB or 40 dB below

nominal for more than 1 ms

• Receiver tolerates jitter as required by ETSI

ETS 300 011
