Specifying RING
Description
The RING characteristic is supported only on those access servers that support the
DSRS signal.
Certain terminal switches and computers need to detect a RING indicator signal (RI)
before they activate. The access server can emulate the RI signal when the port is used
with a BC22R or equivalent cable that crosses the DSRS signal of the access server
over to the RI pin on the device. For information on this cable, refer to the access server
hardware documentation.
When the port RING characteristic is set to enabled and MODEM CONTROL or
SIGNAL CONTROL is enabled, the access server asserts and deasserts DSRS once
every 2 seconds. This continues until either the access server detects DSR or 30
seconds have elapsed. Upon receiving DCD, the access server establishes the
connection. DTR and RTS are asserted unless DTRWAIT is enabled.
