For EIA-530 and V.35 interfaces, configure to-DCE signals by including the
rts statements, specifying the
dtr (assert | de-assert | normal);
rts (assert | de-assert | normal);
For X.21 interfaces, configure to-DCE signals by including the
specifying the assert , de-assert
control-signal (assert | de-assert | normal);
Assertion is when the positive side of a given signal is at potential high-level output
voltage (Voh), while the negative side of the same signal is at potential low-level
output voltage (Vol). Deassertion is when the positive side of a given signal is at
potential Vol, while the negative side of the same signal is at potential Voh.
For the DTR signal, you can configure normal signal handling using the signal for
automatic resynchronization by including the
auto-synchronize option:
dtr {
auto-synchronize {
duration milliseconds;
interval seconds;
}
}
The pulse duration of resynchronization can be from 1 through 1000 milliseconds.
The offset interval for resynchronization can be from 1 through 31 seconds.
For EIA-530 and V.35 interfaces, configure from-DCE signals by including the
, and statements, specifying the
dcd dsr
cts (ignore | normal | require);
dcd (ignore | normal | require);
dsr (ignore | normal | require);
For X.21 interfaces, configure from-DCE signals by including the
specifying the ,
ignore normal
indication (ignore | normal | require);
For EIA-530 interfaces only, you can configure from-DCE test-mode (TM) signaling
by including the tm statement, specifying the
tm (ignore | normal | require);
To specify that the from-DCE signal must be asserted, include the
the configuration. To specify that the from-DCE signal must be ignored, include the
option in the configuration.
