of a secondary cross connect box. It is

based

on

the rule of

“one

pair in and

two

pairs out”, which means for every feeder

pair entering the cross connect box there

are typically

two

distribution pairs leaving

the box.

User input demand level

triggers

placement of a primary cross connect box

(SAI, serving area interface).

In

non-core

clusters, the primary SA1 are placed

adjacent to the Digital Loop Carrier

(DLC), at the center of the cluster.

Primary SAIs are not placed in core

clusters.

and defective material.

Reflects the percentage of traffic that

originates and terminates

on

the same ring.

Used to calculate the total switched traffic

per ring.
