I've been getting conflicting answers to hardware needed for a new remote 
site we are setting up.  I blame myself more due to the fact that I'm 
still very green at this stuff and my inability to ask the question 
intelligently enough.  I wanted to throw this at the trusty cisco-voip 
group of peeps.

New Remote Office Equipment:
Cisco 2821-V/K9 with PVDM2-32U48 using a VWIC2-1MFT-T1/E1

Having an issue with the LEC on getting a T1/PRI into the office.

The choices we have been given:

1.  Backhaul a T1/PRI to a CO thats farther away but the costs just 
doubled.
       - I can use the above equipment with this option but do I have to 
worry about distance to the CO?

2.  Analog group of lines (8 POTS lines)
      -  With this option, my Multi-Flex T1 card is useless.  Will the 
EVM-HD-8FS/DID module do the trick for me?   Can I use the DID ports on 
this module or do I need to add the EM-HDA-6FXO module?

3.  Trunk group of DID's with no CID
      - What hardware module would I need for this option?  This option is 
being talked about the most because of cost.

I've got a Call Manager Cluster at the home office with this site using 
SRST if the wan link goes away.  I'm running CM 4.1(3)sr1.

Any response would be appreciated.   This is our first remote office and 
its been challenging but loads of fun at the same time.
