... and to continue on, the channel bank would be told to accept sync from the 
asterisk card, which is synchronized to the incoming span from the telco.

There can be only one clock and you must engineer your system such that

describing it's not difficult but when you have multiple spans coming from 
multiple providers it can get hairy.
