Extended Extensions Prerequisite Option

Before implementing the Extended Extensions Solution, you must determine if your phone system supports the Supervisory Disconnect Tone. While many manufacturers support this function, some do not.

To determine if you system provides the Supervisory Disconnect Tone, make a call from extension to extension across the phone system in question. Then listen on one end of the call and have someone hang up the other end. If you hear a loud busy tone played by your phone, then your phone system does provide the Supervisory Disconnect Tone and will work with the Extended Extensions Solution on the previous page.

If you do not hear the tone, you will have to use the Extended Extension Upgrade Solution, which is outlined below.

To be able to make calls from the dial tone of either site as well as being able to call to any of the extensions at either site, even though your phone system does not play the Supervisory Disconnect Tone, you simply have to install an FXS and FXO unit at each site.

The FXS at each site is connected to one of the trunk ports of the phone system, while the FXO at each site is connected to a line port.

In effect, two toll-free extensions now link the office PBX's through the Internet. Anyone in either office can dial an extension in the other office from their existing desk phones without toll charges.

Furthermore, anyone can access a local dial tone in the other office and place “local” calls, remotely!
