13.5 PSA-L (BK) UNIT / PSA-L (WH) 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)
