Résumé
Throughout T1's long life, network administrators have mainly learned it by apprenticeship, stumbling on troubleshooting tidbits and filing them away until they were needed again. This book brings together in one reference the information you need to set up, test, and troubleshoot T1. T1: A Survival Guide covers the following broad topics:
- What components are needed to build a T1 line, and how those components interact to transmit data effectively
- How to use standardized link layer protocols to adapt the T1 physical layer to work with data networks
- How to troubleshoot problems and work with the telephone company, equipment manufacturers, and Internet service providers
In spite of its limitations, T1 is a proven, reliable technology that currently meets the need for medium-speed, high reliability Internet access by institutions of many sizes, and it's likely to be around for a while. T1: A Survival Guide will take the guesswork out of using T1 as a data transport.

L'auteur - Matthew Gast
Matthew Gast was born on the Great Plains of the Midwest, near Chicago. Living on the Great Plains, he could almost see all the way to Iowa, where he later attended Grinnell College. In college, he started two significant long term relationships. The first is with the fiercely independent Alison Burek, a musician, painter, and Renaissance woman. To the great joy of their two cats, they were married shortly after graduation.
