PSA-L (BK) UNIT

The PSA-L UNIT (Power Save Adapter), an optional adapter for the ITL/DTL

Terminals, is used with IP telephones to make or receive a call using the

Public Switched Telephone Network (PSTN) when a call cannot be made or

received using the Local Area Network (LAN). When a power failure occurs,

the IP telephone is automatically switched to the PSTN. When power is

restored, the IP telephone restarts and connects to the network unless a

conversation is in progress on PSTN. The PSTN call must be completed by

going on-hook before the connection to the LAN is restored. The unit features:

Survivability in case of power failure or network congestion

Support on modular terminals (ITL/DTL)

PSTN Type = analog PSTN

Dial method – MF/DF (10pps)
