DS3 Fundamentals manual

$29.95

DS3 or Digital Signal level 3, is a Copper based technology that has existed for over 50 years.  The long distance telephone network was largely built around T1 and DS3 circuits after World War-II, and many locations within and outside of the telephone network still use DS3 as a form of transporting voice and data.  This manual is an excellent over of DS3 for a technician, trade school or community college, where the need to understand Copper based transport still exists. This manual is available in print and e-book formats and can be used by organizations who conduct internal training for telecommunication technicians.  Supporting PowerPoint and tests are available from DTS; please call for pricing.
