Bt8370/8375/8376  
2.0 Circuit Description  
2.8 Transmitter  
Fully Integrated T1/E1 Framer and Line Interface  
UMC forces DS0 channels containing eight 0s to be replaced with the  
10011000 code, per Bellcore TA-TSY-000278.  
NOTE: RCVR's ZCS decoder cannot recover original data content from a UMC or  
B7ZS encoded signal, or from a PDV-enforced one.  
The TPOSO/TNEGO output pins provide access to the P and N rail unipolar  
data before it is sent to the TLIU. The output on TPOSO/TNEGO can be changed  
from dual rail unipolar to NRZ unipolar data (TNRZO) and to multiframe sync  
clock (MSYNCO), using the Transmit NRZ Data (TNRZ) bit in TCR1[addr 071].  
The TNRZ setting does not affect the XTIP/XRING output.
