Hey Jeffbb,
Thanks for that mate. Have read them before, but nice of you to point them out.
At the minute I'm looking to see how and if you can integrate a DSL connection into an SDH ring. Cant see why a business would have to fork out a lot of money to get a SDH ring between it's main business sites and then pay extra for a separate and very fast connection to handle multiple VPN connections over DSL from home based employees.
