LEAST COST ROUTING (LCR) SETUP
The personal LCR option for the SCX5D allows you to operate both a regular public switched
telephone network (PSTN) landline phone account and a GSM wireless account through a sin-
gle deskphone. This gives you two separate lines, and allows you to take advantage of lower
calling costs, depending on whether you are connecting to someone via a PSTN or a wireless
network. You can also connect additional phones to the SX5D, but these will only operate over
the GSM network (they cannot access the PSTN). In order to make calls or receive calls over
the PSTN, you must use the SCX5D deskphone.
How to Connect Your SX5 to the Landline PSTN
1) Connect the wall jack to the unmarked jack on the SX5.
How to Connect Additional Phones to Your SX5
1) Connect your additinal telephone to the jack on the SX5 that is marked with a telephone
icon.
NOTE: Be sure to connect to the appropriate RJ-11 jacks, because improper connections could
cause damage your SX5.
How to Set the LCR Default
You can set the SX5D to operate on either the PSTN or the GSM network when you pick up the
handset. You can then set a prefix to dial to access the other service. The factory default is
GSM.
1) Press the MENU key.
2) Select Settings, then Extension Settings.
3) To set the system to operate over the PSTN when you pick up the phone, select Internal.
To set the system to operate on the GSM wireless network, select External.
4) To set a prefix for accessing whichever system you did not select in Step 3, select Prefix.
5) Enter up to two digits for the prefix you wish to use.
The factory default prefix is “#”.
6) Press OK.
