4-20 T ERMINAL C ONFIGURATION AND T ESTING
Invert Data
In the invert mode (YES), transmit and receive data are inverted at the port
interface. This function may be used as a means of guaranteeing ones density
when the data is composed of SDLC type protocols. The choices are Yes and No.
CTS/DSR/ DCD Control
Setting any of these three fields to Force True or Force False allows the forcing of
the port control lead output state. Internal allows for normal operation.
Alarm on DTR Loss
Selecting Enable allows the unit to go into alarm on loss of DTR. The default
setting is Disable.
Dial Backup
Parameters
The Dial Backup Parameters screen (Figure 4-10) allows configuring the DBU
port. The DBU functionality is enabled by selecting two of the eight available
alarm indicators or by selecting Any. These parameters can be any one of nine
errors (LOS, ES, SES, UAS, LOF, RAS, AIS, BPV, ANY). These parameters allow
establishing pre-defined thresholds (set in the Alarm Parameters screen) and
initiating dial backup when these thresholds are exceeded.
See Alarm Configuration on page 4-17 to set the threshold parameters.
Alarm Reset Timer
This field can be set from 0 to 900 seconds. If this field is set to 0, the unit
remains in dial backup mode even if the T1 circuit is re-established. If this field is
set from 1 to 900, the circuit is up for that period before it re-establishes.
See Alarm Configuration on page 4-17 to set the thresholds for this field.
