With an analog line connected, the PSA-R adapter will automatically switch to the analog line
connection when power is lost.

When the PSTN line has been activated either manually by the switch or due to a power
failure, use the dial pad buttons (0-9, *, #) to place an outside call.
Other than receiving calls, no other keyset functions are available.
●
The # and * keys are not functional if the DTMF/DP selector switch is set to pulse mode.
●
When a call is received, the PSA-R adapter rings and the LED blinks. If the PSTN-IP/Digital
Switch is set to PSTN (functions as power failure terminal), answer the call by pickup up the
handset. If the switch is set to the IP/Digital position, the terminal functions as a system
terminal when there is power and as a power failure terminal when the power is off.
If an analog line is connected, the PSTN-IP/Digital selector switch can be used to switch to
the analog line manually (without having to lose power). If an incoming call is received on the
analog line while the PSA-R is connected to regular communications server trunks, the
terminating LED blinks and a ring tone is heard.
You must complete your present call prior to answering the analog trunk call, otherwise
●
your original call will be disconnected.
Other than receiving calls, no other keyset functions are available while used as a power
●
failure terminal (PSTN).
Use the Volume Control buttons located on the PSA-R adapter to adjust the volume level.
Other than receiving calls, no other keyset functions are available.
●
The IP keyset restarts and reconnects to the network LAN. However, if you are on a PSTN
call when the power is restored, your conversation will continue until the handset is placed
into the cradle. Once this occurs, the IP keyset will restart and reconnect to the LAN. If the
PSTN mode was manually set by the switch, it must be set back to the IP/Digital position
before the adapter will switch modes.
Other than receiving calls, no other keyset functions are available.
●
Set the DTMF/DP Selector Switch on the bottom of the terminal to either DTMF or DP.
