3116-10 NIU with Performance Monitoring
- NOTE -
Hereafter, the 3116-10 DS1 Network Interface Unit with
Performance Monitoring also may be referred to as the NIU,"
the unit," or 3116-10."
1.3
Product Purpose and Description
The Westell 3116-10 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 3116-10 Issue B is a member of the Westell
PROACT family of T1 NIUs that provide standard maintenance
loopback plus collection and reporting of DS1 performance sta-
tistics. These performance monitoring capabilities allow service
providers to PROACTively" respond to facility performance
degradation, thereby improving the availability of Hi-Cap T1
circuits.
