IEEE 820 2005 Edition, September 22, 2005 Standard Telephone Loop Performance Characteristics
More info
Description / Abstract:
This standard covers the general parameters and characteristics
associated with telephone loops from the subscriber signaling and
analog voice frequency interface to the local Class 5 switch
interface. It includes only those business and residential lines in
the North American public switched network where no special
performance requirements are involved.
This standard provides common denominators for subscriber line performance, independent of facility types, construction processes or equipment, and circuit provisioning methods.
Purpose
The purpose of this standard is to describe quantitatively the performance characteristics of telephone loops and indicate current acceptable performance criteria.
