Chapter 2: What You Need To Start
Megabit Modem 400F, 500L, 600F, and 700F User Manual 13
Phone Service
If you get phone service with your data service, you need the following:
• S1 Network Interface Device (or other POTS splitter) installed by your service provider
• RJ-11 phone jacks for phone service
The POTS splitter is a device that separates data transmission from phone service. After
installing the POTS splitter, connect separate jacks for data and for phone service. Ensure that
your service provider indicates which jacks are for data and which jacks are for phone service.
