Tieing 2 key systems together with fxo/fxs and 1760 routers

Question

Hello,
I need some programming help from someone good on voice. I've got two offices that I'm trying to tie the phone systems together with 2x Cisco 1760 routers each with 2x PVDM-256K-4 1 DSP Modules. I've got the layout below and am basically looking to do two things.
First, I would like ext. 210 from the first site to dial a co group “1” or directly access a “CO line” that is connected to the Cisco and get dial tone to be able to dial the directory number for a “CO line” with the same setup at the second site and have it able to be answered like a normal call and be transferred.
The second connection I would like is to have ext. 210 be able to dial locally to one of site 1's analog single line extensions and have the Ciscos make a connection through to site 2 and go off-hook on one of the analog single line extensions of site 2 in order to get a site 2 dial tone and be able to dial locally @ site 2 to any extension, or dial one of site 2's co groups or directory number for one of site 2's real CO lines and place a “local” call to the outside world from site 2's lines.
Obviously this process would all be reversed for site 2 accessing site 1. I've come across a couple of documents, like ID: 15405, and a section of a VoIP Configuration guide labeled OL-1070-01 and have some command structure available, but the concept of how it all takes place and should be configured is a little fuzzy.
Thank you,
Mark

OK, let me simplify things. I think I'm putting way too much thought into it all. I've got site A and site B. Site A (currently for testing) has a single line extension from Site A's key system plugged into port 0 in fxo card in slot 2. Site A will have a patch from port 0 in fxs card in slot 3 to a CO line on the key system. Site B has the same setup. Both have fa 0/0 configured with IP addresses on the same network (just to simulate the connections - later I will actually move these to two separate internet feeds for more advanced testing).
Currently for testing I have disconnected the fxs patches to the phone systems and just have a regular analog phone plugged in. When my phone plugged into Site A goes off hook, I get dial-tone from the extension hooked up to Site B (which is the exact way I want it). When my analog phone is plugged into Site B (port 0 of fxs card in slot 3) and goes off hook, it will ring port 0 of fxs card in slot 3 of Site A. This I don't understand. If I can get both to behave like Site A, I'd be happy.
I need to know if this makes sense to anyone on how I want this to operate? Is it achievable?
Here's my base config on it (Site A first, then Site B):
