3.2.2.3.2 Automatic V.54 Loops
The system supports only a local V.54 loop managed by the line 141. The support of the V.54
loops is software programmable. You can use the command AUTOLOOP to adjust automatic
loop reaction: Lines 140 and 142 are not supported by the system.
3.2.2.4 Input Sensor and Output Relay
FlexDSL Orion3 devices can be equipped with IO module containing 4 Inputs and 4 Outputs.
Input is a pair of contacts connected to current detector; if the current is present in the electric
circuit the Input switches its state to "Closed". Input changes its state into "Open" if no current
detected in the electric circuit.
Output is a pair of contacts (normally-open and normally-closed) and common wire connected to
relay. Relay may stay either on "Active" or in "Inactive" state. Active state means that the current
passes through relay coil and common contact is connected to the normally-open contact. Inactive
state means that no current passes through relay coil and common contact is connected to
normally-closed one.
