PSA-R Adapter (Figure 4-46 - Figure 4-47)

Using the PSA-R Adapter provides power failure capability for the IPhone IP keysets. This allows a user to
make or receive an outside call using the central office if an IP keyset is unable to make or receive a call
using the LAN, if for instance, there was a power failure. In this case, the connection of the keyset would
automatically be changed from LAN to PSTN (public switched telephone network). This allows the dial pad
keys (0-9, * and #) to be used for placing and receiving calls - no other keyset functions are available. As the
IPhone only has one connector available for additional adapters, if this adapter is connected, no other
adapter can be installed on the phone.
The change from LAN to PSTN occurs in the following instances:
●
No power supplied to the keyset
●
PSTN is selected using the LAN/PSTN Change Switch on the adapter
ing correctly and power is available.
●
If the initial software operation for the IP keyset has not yet been completed before the IP keyset is
powered up
When installing or removing the adapters, the keyset should first be unplugged from the system. Telephones
with any adapters installed cannot be wall-mounted. The bracket will not accommodate the adapter(s).

Installing the PSA-R Adapter:

1. Unplug the line cord from the keyset.
2. The adapter should be installed on the right-hand side of the phone (beneath the handset). Using a
flat-head screwdriver, remove the plastic punch-out piece covering the connector.
3. Set the dip switches on the PSA-R adapter to the required position.
