Hi,
New user here. I think I have my PPP multilink setup correctly. Though I am getting AL lights on one of my connections via a VWIC2-2MFT-T1/E1 card. One AL light is on at each location. Though I checked with my ISP and they said it was my network cables as everything looked good on their end. Currently one T1 circuit is connected at each end so users do not see a disruption. This is a new install with two routers and the config is shown below.
