•
Enable operation: enables or disables the interface.
•
Enable tests: enables the test activation on this interface by the test menu or the
management.
•
Number of channels: sets the number of time slots in the interface. It can range from 1 to
36 2-wire DSL channels and 1 to 72 4-wire DSL channels.
•
CT105 (RTS): indicates if the CT105 controlled signal, generated by the DTE, signaling
transmission request should be considered or ignored (forced ON).
•
CT108 (DTR): Indicates if the CT108 control signal, generated by the DTE, signaling that
the terminal is ready, should be considered or ignored (forced ON).
•
Clock: Defines which clock will be used to sample the CT103:
o
General synch source: the interface will use as clock the equipment clock source
(regenerated from an interface or internal);
o
External (CT113): the interface will use the CT113 signal to sample the CT103;
o
CT104 sync CT113: the interface will use the CT113 signal to sample the CT103
and to generate the CT104;
o
CT113 unlooped CT114: the CT113 clock is not passed on to the CT114, which
will be the system clock. The CT113 signal is sampled according to the CT113.
Recommended when connecting the DM991 to some routers models;
•
CT128 (ERC): selects if the data sent in the CT104 should be synched with the CT128
signal of the interface. If the previous parameter, clock, is selected for CT104 sinc.
CT113, this object can not enabled;
•
Invert TX clock: inverts the sampling clock border selected to sample the CT103.
•
CT103/CT104 Monit: enables the monitoring of type of information transmitted or received
in digital interface.
