Planning Your System - AT&T SynJ SB67158 User Manual

Getting started

Planning your system

The SynJ SB67158 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.
