I installed my first T-1 module in a partner last week. The PACSR6 had been in service for about a year. It was a bear to reconfigure and get connected to the PACS, but the T-1 came right up. There is a software patch you may want to load, but research it first. If it's not absolutely required, DON'T LOAD IT!! I talked to the TSO about that. You'll have to know how to use the Green Card and have access to e-Flash Tools website.
