This is possible but you would need access to the Provider routers or
ask them to do the configs.
The more advanced way of doing this is to run HSRP between the two
routers so the lan machines always have one "gateway ip" (virtual ip for
HSRP)
I would then run some sort of routing protocol between the 2 CPE's with
floating statics so they are aware if one or the other's link goes down.
You can also do this on the CPE by tracking an interface with HSRP/VRRP
This is a very brief explanation but it's the way I would do it.
Obviously it gets more complex if your are peering with the provider via
BGP etc

Subject: Back up an MPLS VPN with another two router connected through
leased line link
Hi Experts.
I have two site A and B, each with 878 router to provide MPL VPN I have
no
access one these two router. I want to implement a leased line back up
for
this VPN link. I installed 1841 with WIC-1T in each of these two site.
How I
could configured my two router with their TDM link to be an automated
backup
for the provider router?
