Chapter 2: What You Need To Start

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.
