Selectors 3 and 4: Delay of FAX line disconnection when switching to the pseudo-ringing external
l
When the equipment receives a phone call, it can make the connected external telephone ring (so
called pseudo-ringing). During pseudo-ringing, if you pick up the handset of the external telephone,
the line might be disconnected due to cut-off of the line current.
To hold the line, the equipment may supply line current by making use of the pulse generator
circuit that forms a parallel loop. This way the FAX line disconnection may be delayed. These
selectors determine the delay period.
