SX5D FIXED WIRELESS LCR PHONE
The SX5D Fixed Wireless LCR (Least Cost Routing) Phone allows calls to be placed through the
wireless GSM network or the public switched telephone network (PSTN) - see Figure 21. This
capability enables users to take advantage of favorable rates based on type of call (local or long dis-
tance), time of call, and receiving party (wireless subscriber or PSTN subscriber).
Connect the SX5D Personal LCR Phone to the Landline (PSTN)
The SX5D Personal LCR Phone must be connected to the PSTN in order to take advantage of
least cost routing. Once it is connected, both wireless and PSTN services will be available.
Wireless service is the default setting for primary service (what is automatically active when the
SX5D goes off-hook). PSTN service can be connected by pressing the FLASH key before enter-
ing the phone number. See the Change the Default Service and Change the Alternate Service
Prefix sections of this manual for instructions.
1. Using RJ-11 cable (not supplied), connect the PSTN wall jack to the unmarked jack on the
SX5D Personal LCR Phone - see Figure 22.
NOTE: Make sure to connect the PSTN to the proper RJ-11 jack on the SX5D. Improper
connection may damage the SX5D.
