 - Surf the Internet and talk on the phone at the same time
 - Just one phone line can be used for several pieces of equipment
 - Voice conversations over ISDN are crystal clear and are CD quality

 ISDN = 2B + D
Basic Rate Interface (BRI) ISDN, enables a standard phone line to carry three separate digital channels: a 16Kbps "D" (data) Channel and two 64Kbps "B" (bearer) Channels.  The D Channel carries signaling information, and the B Channels carry voice and data.  The two B Channels can be combined to provide transfer speeds of up to 128Kbps.  The B Channels can be configured to carry either voice, data, or both.  An example:  You are on the Internet and you would like to call a particular company to order their product.  While you're still on the Internet picking up the telephone will signal the RTI central office that you wish to place a voice call.  You will then get a dial tone and will then be using one B Channel for the Internet and one for Voice and both are digital quality.  To find out more about ISDN contact us today.  Or, visit our office for a hands on demonstration.
