ASN.1 specification and protocol stack

[Thomas Arts]

Could anyone point me to a relatively small ASN.1 specification
of a protocol together with the accompanying protocol stack?

We are looking into testing tools and would like to have a case
study to see how well the testing performs.

Thanks
Thomas
