Description
Lets you specify the signaling required by the external
device connected to the system. Specify normal or
inverted, as appropriate. In most cases, normal signaling
is appropriate.
If your system is connected to Ascend equipment, you
may need to set CTS to Ignore.
Specifies that the system should begin the call when it
detects a DSR signal.
Specifies how long the system waits to end the call after
a DCD signal is lost (for example, during a call via
satellite).
Specifies how long the DTR signal goes low after the far
site hangs up. When the pulse is too short, the call may
not clear.
If your system is connected to ADTRAN equipment, you
may need to adjust DTR pulse duration.
Specifies whether the call starts when H.320 data is
detected at the V.35 interface while set for direct
connect.
Description
Allows a Polycom HDX system connected to
cryptographic equipment to signal when it loses video
synchronization during a call. The cryptographic
equipment can then resynchronize with the far site.
Allows the system to send the resynchronization pulse on
the RTS signal. Select this setting if your data
communications equipment uses the V.35 or RS-449
capability of the serial V.35/RS-449/RS-530 network
interface.
Note: When you select this setting, the RTS no longer
functions as the Request To Send signal.
Specifies whether the system should set the time
between resync pulses automatically or use the number
of seconds you enter.
