Specifying RING

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.
