MLPPP With 2 T1

WE have a hub and spoke frame relay network. I want to add a secondary T1 to double bandwidth.. I do not want to use load balancing but want to bond the 2 T1's together. I know I can use MLPPP to bond the T1's. I am confuse on how to configure the interface for frame relay....

You have to work with your telco to get bonded T1 multi-link frame-relay. You simply cannot do it on just your end. Typically, the telco will bring in an imux that will connect to your router by either HSSI or v.35.
Either that, or they will use IMA to bond ATM T1's together at the router and not use frame-relay at your end.

Telco said they are going to split the primary PVC going to the frame relay hub  between the the 2 T1's. Does that mean they are already doing inverse multiplexing of the T1's and if they are I have a problem because I am planning on using my PA-MC-4T1 card on my 7206 to do this and I do not have a budget to buy a different card.  Also, right now I have multipoint on the hub and point-to-point on the spokes configure on my frame network, I want to change it to point-to-point on the hub so I can monitor my connection to each site since it will have a subinterface going to each spoke on the network. Is this a good idea?
I would understand splitting the PVC as meaning giving you two PVC's to two different T1's, NOT combining in a multilink.
You can do your own load-sharing/load-balancing between the two PVC's.

It is always better to have multiple point-to-point subinterfaces rather than point-to-multipoint.
You can do a lot more things with interfaces than you can routes. Connection monitoring and bandwidth monitoring/restricting among the many...
If they are providing 2 PVC. Will I be able to use Cisco MLPPP to do load sharing, as far I can undestand with MLPPP you have to use a group and assign your T1 interfaces into this group. How do I configure do I configure the serial interface to use this group ?

Thanks for the help. I have another question can I have all the remote sites configure to have all the same DLCI number and create subinterfaces in the HUB with different DLCI number for each subinterfaces ?
Are you still working on this? Can you close out the original question?

Thanks!
