Product Purpose and Description
The Westell 3115-80 Issue B T1 Network Interface Unit with
real-time Performance Monitoring serves as an interface be-
tween a T1 metallic span, or a customer premises-based fiber
multiplexer, and the intra-building Customer Premises Equip-
ment (CPE). The 3115-80 Issue B is a member of the Westell
PROACTt family of T1 NIUs that provide standard mainte-
nance loopback plus collection and reporting of DS1
performance statistics. These performance monitoring capabili-
ties allow service providers to PROACTively" respond to facility
