FUNCTION
LIUODO
7
Line Interface Open-Drain Option. This control bit determines whether or not the
TTIP and TRING outputs are open drain. The line driver outputs can be forced
open drain to allow 6VPEAK pulses to be generated or to allow the creation of a very
low power interface.
0 = allow TTIP and TRING to operate normally
1 = force the TTIP and TRING outputs to be open drain
CDIG
6
Customer Disconnect Indication Generator. This control bit determines whether
the line interface generates an unframed ...1010... pattern at TTIP and TRING
instead of the normal data pattern.
0 = generate normal data at TTIP and TRING
1 = generate a ...1010... pattern at TTIP and TRING
LIUSI
5
Line Interface G.703 Synchronization Interface Enable. This control bit works
with CCR7.0 to select G.703 functionality on the transmitter and receiver (Table
8-B). These bits determine whether the line receiver and transmitter should
receive/transmit a normal E1 signal (Section 6 of G.703) or a 2.048MHz
synchronization signal (Section 10 of G.703).
IRTSEL
4
Receive Termination Select. This function applies internal parallel resistance to
the normal 120
W external termination to create a 75W termination.
0 = normal 120
W external termination
1 = internally adjust receive termination to 75
