ATLAS 800 Series System Manual Dual Video Option Module
Configuration
Data Write security: 3; Read security: 5
Controls the inverting of the DTE data. This inversion can be useful when
operating with a high-level data link control (HDLC) protocol (often used as a
means to ensure 1s density). Select either
NORMAL or INVERTED. Data inversion
configuration must match at both ends of the circuit.
CTS Write security: 3; Read security: 5
Determines the behavior of the Clear To Send (
CTS) signal. If set to NORMAL,
CTS will follow the value of Request To Send (
RTS). If set to FORCED ON, CTS
will always be asserted.
DCD Write security: 3; Read security: 5
Determines the behavior of the Data Carrier Detect (
DCD) signal, also called
RLSD on V.35 interfaces. If set to
NORMAL, DCD will generally be asserted
when the interface is capable of passing data. If set to
FORCED ON, DCD will
always be asserted.
DSR Write security: 3; Read security: 5
Determines the behavior of the Data Set Ready (
DSR) signal. If set to NORMAL,
DSR
will generally be asserted when the interface is capable of passing data. If
set to
FORCED ON, DSR will always be asserted.
DTR Write security: 3; Read security: 5
Selects the response to DTR transitions. Table 4 lists the configuration options
for the DTR parameter with respect to the current configuration for the module
in the Dial Plan.
Table 4. DTR Descriptions
Dial Method (Dial Plan) DTR Setting Description
Dial on DTR Recognize DTR Call is dialed when DTR is high and disconnects when DTR
goes low.
Ignore DTR Call will never connect.
RS-366 Recognize DTR Call is dialed if DTR is already high and disconnected when
DTR goes low.
Ignore DTR Call is dialed regardless of DTR state and must be
disconnected manually.
Manual Recognize DTR Call is dialed if DTR is already high and disconnected when
DTR goes low.
Ignore DTR Call is dialed regardless of DTR state and must be
disconnected manually.
