Configuring with an ASCII Terminal
5-20 Campus-RS Fractional Interface Card User Manual
• STD sets to signal according to the standard rules for control signal
operation found in RS-449 and RS-530 interfaces, depending on the
signal:
– RLSD is on as long as the HDSL link is synchronized. If the HDSL
link is not synchronized, then RLSD is off.
– TM is on whenever a loopback function is active at either the local
or remote unit. The TM signal is affected by both V.54 loopbacks
and loopbacks that are initiated through the LCD or terminal menus.
– DSR follows the state of the Data Terminal Ready (DTR) input
signal. When the DTR input is turned on, the DSR output is turned
on. When the DTR input is turned off, the DSR output is turned off.
This type of operation is consistent with standard operation for
non-switched communications equipment operating on a dedicated
private channel, such as HDSL.
– CTS follows the state of the Request to Send (RTS) input signal.
When the RTS input is turned on, the CTS output is turned on. When
the RTS input is turned off, the CTS output is turned off. This type
of operation is consistent with standard operation for non-switched
communications equipment operating on a dedicated private
channel, such as HDSL.
To configure the control signal options to the desired settings:
1 From the Data Port Settings menu, do one of the following:
• for CTS type then press
• for DSR type then press
• for RLSD type then press
• for TM type then press
The selected control signal option changes to the next available setting.
2 Repeat the previous step until the Data Port Settings menu displays the
desired control signal option settings.
