CTS
Setting this field to Force True (Force T) or Force False (Force F) allows the
forcing of the port control lead output state. Internal (Int) allows for normal
operation.
DSR
Setting this field to Force True (Force T) or Force False (Force F) allows the
forcing of the port control lead output state. Internal (Int) allows for normal
operation.
DCD
Setting this field to Force True (Force T) or Force False (Force F) allows the
forcing of the port control lead output state. Int (internal) allows for normal
operation.
LL
This option allows you to enable (En) or disable (Dis) the local loop activation by
the local loopback signal pin J (V.35) or
pin 18 (EIA-530) on the DTE interface.
RL
This option allows you to enable (En) or disable (Dis) the remote loop activation
by the remote loopback signal pin BB
(V.35 ) or pin 21 (EIA-530) on the DTE A
interface. Remote loopback causes transmission of V.54 loop or unloop codes to
the far end device.
V54
Selecting Enable (En) allows the unit to respond to inband V.54 loop codes. If
Disable (Dis) is selected, the unit ignores these codes.
DTR Alrm
Selecting Enable (En) allows the unit to go into alarm on a loss of DTR. This
occurs when the DTE port sees that the DTR signal is low. Choices are enable
(En) or Disable (Dis).
DBU Params The Dial Backup Parameters menu allows you to configure the DBU port. You can
enable the DBU functionality by selecting any two of nine alarm conditions (LOS,
ES, SES, UAS, OOF, RAS, AIS, BPV, Any). These parameters allow you to
establish pre-defined thresholds (set in the Alarm Parameters screen) and initiate
dial backup when these thresholds are exceeded. See page 26 for alarm
configuration from the front panel interface.
State
Lists the current DBU status:
Disabled - DBU function is disabled.
Enabled - DBU function is enabled and is monitoring the Activator 1 and 2 alarm
states.
