Getting started
Planning your system
The SynJ SB67138 package includes one telephone base and one cordless
handset (already registered). The included cordless handset has been assigned
extension number 1. The system supports a maximum of four external lines,
which are provided by your telephone service provider.
You can expand the system by adding a combination of up to 10 additional
cordless handsets (AT&T model SynJ SB67108), desksets (AT&T model SynJ
SB67148), and one cordless headset (AT&T model TL7600). The system
automatically assigns an extension number to each device you add.
You can use a DECT 6.0 repeater (AT&T model SynJ SB67128) to extend the
operating range for cordless handsets to cover areas where the signal is very
weak or not available.
NOTES:
If you have two or three telephone lines, you will need one two-line adapter for every two lines. If
you have four telephone lines, you will need two two-line adapters.
If your establishment has four telephone lines from one-line telephone jacks, you will need to
purchase a telephone line cord (purchased at an electronics store in your area) or equivalent for
each two-line adapter.
If you have high-speed Internet service (DSL - digital subscriber line), you need to have an external
or internal DSL splitter for each telephone line installed at your location by your DSL provider.
