ABSTRACT: This Technical Reference (TR) contains the view of Telcordia on generic requirements and objectives for digital microwave radio systems with DS3 (44.736 Mbps) interfaces intended for use by Local Exchange Carriers (LECs).

The particular electrical and physical requirements and objectives cited in this publication are based on the view of Telcordia on LEC maintenance and operating requirements, transmission objectives, equipment and design standards, and realizable performance to meet typical LEC needs. The function of the microwave digital radio system in the 4-GHz, 6-GHz, and 11-GHz common carrier bands is to reliably relay two or more DS3 signals between DS3 cross-connects.
