Defining Operating Parameters
5-11
8. This parameter appears on the screen only when the service is set for DDS-SC or
CC64.
9. This parameter appears on the screen only for units equipped with the Model A
or C Aggregate card.
10. This parameter does not appear on the screen when the service is set for DDS or
CC64.
11. This parameter appears on the screen only when the service is set for DDSNI, the
Location parameter is set to central, and the Network parameter is set to
multipoint.
12. This parameter appears on the screen only when the service is set for DDS-SC
and the DTE rate is set to 56 Kbps.
The following sections explain the function of each DAP parameter.
Location
The Location parameter specifies whether your DAP is located at the central or remote
site in the network. The proper setting is essential to the operation of the Multidrop and
RCP features.
Network
The Network parameter specifies the network configuration for your unit. In a point-to-
point network a single central site DAP exchanges data over the telephone line with a
single remote site DAP. In a multipoint network a single central site DAP exchanges
data over the telephone line with DAPs located at two or more remote sites.
RTS
This parameter specifies whether the RTS signal is controlled by the DTE or held in a
constant On condition. When DTE is selected, the RTS signal is controlled by the DTE.
DCD
The DCD parameter specifies whether the DCD signal is always in a high condition or is
controlled by the DAP. When Constant is selected, the DCD signal is always high except
when in a test mode. When DCE is selected, the DCD signal is controlled by the DAP.
