1

Inlet to outlet connection is via a single cross point.

Inlet to Outlet connection is via multiple cross points

2

Use of single cross point per connection leads to better quality link

Use of multiple cross points can degrade the quality of a connection.

3

Every individual cross point can be used for just one inlet/outlet pair connection.

Same cross point can be usedestablish connection between some inlet/outlet pairs.

4

A specific cross point is required for each specific connection.

A specific connection may be established by using sets of cross points.

5

If a cross points fails, associated connection can't be establish- There is no redundancy.

Alternative paths and cross-points are available.

6

Cross points are inefficiently used. Only one cross point in every row or column of a square or triangular switch matrix is even in use, even if all lines are active.

Cross points are used Efficiently

7

Number of cross points is Prohibitive

Number of cross points is reduced significantly

8

A large number of cross pointsin every inlet/outlet results in capacitive loading.

There is no capacitive loading problem
