[c-nsp] OT: Book on Telco stuff

[Nick Shah]

Hello All

I was wondering if anyone has come across a book which explains the
following technologies and their interworkings in clear succint manner.
The particular questions that can/may be answered in that book would be:

- Frame/ATM interworking (now that's easy and can be found on CCO)
- SDH rings, and the redundant natures
- SDH platforms
- E1/T1 aggregation and how they can be delivered in aggregated manner
- BPX/MGX interoperability
- BPX/MGX platforms

Cisco had a good course on CCNA WAN switching(and CCNP also I think)
which has been withdrawn. 

Is there such a book out there ?
