SCTE Clock Phase Control — Receive timing phase control. This parameter
applies only when the attached cable is DCE type cable. Depending on the speed
of the device application and the clock phases, particularly those of the return
clock, you may have to set SCTE Clock Phase Control to Inverted (invert the clock)
to ensure correct clock and data phase.
Normal — The receive timing from the remote endpoint (node) is normal
clocking.
Inverted — The receive timing from the remote endpoint (node) is inverted
clocking.
56K/64K Mode — The T1 DSU/CSU mode to be emulated: 56k Mode (n x 56) or
64k Mode (n x 64).
Dial Timer — The amount of time, in seconds, after which dialing is assumed to
be ended if no further digits have been received: 6-60. This parameter applies to
the video dial feature. The RS-366 specification does not require all calls to be
ended with the EON (End of Number) digit. If no EON is available, the CBR
software uses the Dial Timer to determine when dialing is complete. The CBR
software resets the timer each time a digit is received. When the timer expires, the
dialing is assumed to be completed, and the RS-366 driver forwards the call to the
call handling task for further processing.
When used alone, the CBR V.35 interface is used in the lease line environment,
and all of the interface signals are forced to on. When used with RS-366, the CBR
V.35 interface is used in a switched environment. The DSR and CTS&DCD options
allow you to emulate the switched environment by specifying that certain
interface signals should go off in alarm conditions.
DSR Option — Specifies the behavior of the DSR interface signal:
Forced On — Force the DSR signal to on in all conditions.
Follow DTR — Direct the DSR signal to follow the DTR signal.
Toggle — Toggle the DSR signal off for three seconds and then to on after the
DSC goes off.
CTS&DCD Option — Specifies the behavior of the CTS and DCD interface signals:
Forced On — Force the CTS and DCD signals to on in all conditions.
Follow DTR — Direct the CTS and DCD signals to follow the DTR signal.
Follow DTR & DSC — Direct the CTS and DCD signals to follow the DTR and
DSC signals.
Admin. Status — Administrative status: In Service or Out of Service.
