Timing Recovery block M&M..difficulty in understanding

Hi friends,

I have a difficulty in relating the M&M timing recovery block with the
theory and algorithm presented in “Timing Recovery in Digital
Synchronous
Data Receivers” by Mueller and Muller. Can someone help me in
understanding
it or advice me on what to look for. I will be more than happy to get a
little help on this as this thing has kept me busy for weeks now with
very
little success.

Thanks
Ali
