Defining Operating Parameters
5-13
CTS Delay
This parameter allows you to set additional RTS/CTS delay required in certain network
applications. The delay times available are 0, 10, 20, and 40 ms. This is an additional
delay added to the basic RTS/CTS delay. The basic delay is dependent on the DTE data
rate and the method of transmitting the RTS signal to the far end (in-band or out-of-
band). The minimum and maximum delay for a DAP using the out-of-band method is
0.75 to 15.0 ms.
Squelch Primary Transmitter
When this parameter is enabled, the DAP squelches (disables) its primary transmitter.
Note that this setting disables the secondary channel when the service is set for DDSNI or
C64NI and the Network parameter is set to multipoint. This parameter should normally
be disabled.
DSR Off
This parameter specifies whether the DSR signal goes off while the unit is in any test
mode including loops generated by the network (All) or only if the internal test pattern
(e.g. Self-Test or End-to-End Error Test) of the unit is enabled (Tests).
DSR On
This parameter allows you to select the conditions upon which the DSR signal turns on.
When Constant is selected, the DSR signal is on when power is applied to the DAP.
When DAP On is selected, the DSR signal is on if the unit has power, but may turn off
depending upon the option selected in the DSR Off parameter. When the circuit
assurance option (DDS Up) is selected, the Excalibur Multirate DAP does not turn on
DSR if the DDS is not functional and turns it off depending on the DSR Off setting.
Note: When set to Constant, the DSR Off parameter can be ignored since DSR is
always active.
