1. Go to Configuration > Network > Serial > Serial Port n > Advanced.
2. Configure advanced serial parameters as needed:
Answer V.120 calls after n rings (0 = Don't answer)
Controls the answering of incoming V.120 calls. When set to 0, V.120 answering is disabled,
otherwise V.120 answering is enabled on this interface. Enter the number of rings to wait
before answering the call into this text box. This is equivalent to setting the value of the S0
register for the associated serial port.
DCD
Selects how the Data Carrier Detect (DCD) signal is controlled. The available options are:
Auto: Configures the router so that it will only assert the DCD line when an ISDN
n
connection has been established; this is equivalent to AT&C1.
On: Configures the router such that the DCD line is always asserted when the router is
n
powered-up; this is equivalent to AT&C0.
Off: Configures the router such that the DCD line is normally asserted but is de-
n
asserted for the time period specified by the S10 register after a call is disconnected;
this is equivalent to AT&C2.
Pulse Low
n
DTR Control
This drop-down selection box controls how the router responds to the DTR signal. The available
options are:
None: Configures the router to ignore the DTR signal; this is equivalent to AT&D0.
n
Drop call: Configures the router to disconnect the current call and return to AT
n
command mode when the DTR signal from the attached terminal (DTE) is de-asserted;
this is equivalent to AT&D1.
