2621XM WIC-1DSU-T1 to VWIC-2MFT-T1 PPP link connectivity
These 2 routers were communicating with each other until recently between a main office and another office on site ~800 feet away. The link uses an underground copper run which was designated as being a T1 line at some point. Someone wiped the configuration on the local side router. For testing purposes we now have both routers in the same room connected with a custom made T1 crossover cable with pins 1 to 4 & 2 to 5 checked with a cat5 tester. The remote side router has a single port T1 DSU/CSU and the cable is connected to port 0 on the local side router. The config in the remote side router has been left as it was when the link was working so that I can try to compliment or mirror this on the local side router. I'm unable to exactly mirror the config of the remote router as the "service-module t1" is not an available option on the local router. So far I'm not even able to ping across the serial interfaces. I'm not a Cisco expert by any means and would appreciate some help from those in the community with more knowledge. Thanks
Remote end has a single port WIC-1DSU-T1 with the following info/configuration known to have been working:

Local has a 2 port VWIC-2MFT-T1 and I have attempted a new config to compliment the remote site config as best I could:

UPDATE: I determined my contact on site had actually connected the t1 crossover cable to the wrong serial port. I corrected this and made some additional changes to the configs and we are now up and running with verified connectivity. I'll post the info here for anyone else who may benefit:
