When this switch is in the down (normal) position, Carrier
Detect (CD) is On any time customer data is being received and
Off when the receive circuit is idle, (not carrying customer data).
When this switch is in the up (On) position, CD is forced On all
the time.
When this switch is in the down (On) position, Data Set Ready
(SR) is forced On all the time. For the up (normal) position, SR is
turned Off when the network is out of service or a test is in
progress.
When this switch is in the down (enable) position, the DSU 5600
accepts the industry standard V.54 Remote Digital Loopback
(RDL) command from the far end of the circuit.
When this switch is in the up (disable) position, the DSU 5600
does not respond to a V.54 loopback command from the far end
of the circuit.
