Teltone’s Line Sharing Switch and Polling Controller let you take advantage of the unused capacity of your phone lines by allowing up to four telecommunications devices (phone, modems, fax, etc.) to share a single line. They offer the following advantages:

	Rugged, “network quality” design
	Full remote programmability
	Emergency outbound dialing priority
	Access security for remote modems

In addition, multiple Line Sharing Switches can be easily cascaded or paralleled to allow more than four devices to share a single line. Your inbound or outbound data collection and other online transactions will take place as with dedicated lines, but without the extra line cost.
Emergency override access to the phone line can be provided as needed for your application. The Line Sharing Switch operates alone or with the Polling Controller to give you a flexible, cost-effective way to collect data without affecting critical telephone service.
