BIT NAME AND DESCRIPTION
7
Line Interface Open Drain Option.
This control bit determines
whether the TTIP and TRING outputs will be open drain or not. 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
6
Customer Disconnect Indication Generator.
This control bit
determines whether the Line Interface will generate an unframed
...1010... pattern at TTIP and TRING instead of the normal data
pattern.
0 = generate normal data at TTIP & TRING
1 = generate a ...1010... pattern at TTIP and TRING
5
Line Interface G.703 Synchronization Interface Enable.
This
control bit determines whether the line receiver should handle a normal
E1 signal (Section 6 of G.703) or a 2.048MHz synchronization signal
(Section 10 of G.703). This control has no affect on the line interface
transmitter.
0 = line receiver configured to support a normal E1 signal
1 = line receiver configured to support a synchronization signal
4
Receive Termination Select.
This function applies internal parallel
resistance to the normal 120 ohm external termination to create a 75
ohm termination.
0 = normal 120 ohm external termination
1 = internally adjust receive termination to 75 ohms
