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
