A T1 circuit is made up of 24 64-Kbps channels, and you can opt to pay for only a fraction of them. Another wrinkle is called switched T1. Most T1 circuits are dedicated, meaning that the connection is always live and exists between two specific points. A switched T1 circuit works like a regular phone line or ISDN line in that you can make calls to other switched T1 lines. If you're using the T1 circuit to carry voice and data, you'll need a T1 multiplexer, a device that splits the circuit into multiple chunks that you can split between your voice and data requirements.
Prices vary by region.
Lead time for getting a T1 connection can vary from two weeks to a painful six or eight weeks, so plan ahead. 1999 ZD Inc. All rights reserved. ZDNet and the ZDNet logo are trademarks of ZD Inc.
