Looking for books on design of digital switching fields

Switching theory

Hi. I need advice and explanation of some things related to design of digital switching fields ( Time-Space-Time type (T-S-T)).
Can you give some reference or books about it.
There are some questions:
-is S-switch one-way element? I mean he has input (for example 30 )ports and output ( for ex. 40 ) ports and he can switch from input to output, but can't in inverse direction.
-How to calculate a blocking probability for switching fields?

Re: Switching theory

Generally switches are two way elements but it also depends on the design.You can design it either way..
