Seems like if you just repair/replace the CO cable you should be fine.

As to: "I am bringing in new circuit lines, loop start NOT ground start. What card needs to process them, and where are the switches or pins to configure the card for loop start in the documentation." that is a completely different issue and you need a certified Mitel tech or have a lot of experience programming the switch.

Your questions are above the normal scope of this board, generally:

"The board is intended to assist two types of members, end users and professional telephone technicians (installers). If you are a novice or a do-it-yourself end user looking for advanced assistance with a system install, you should post your question with as much detail as possible and expect a response from a qualified installer who can take your issue off the board and answer your questions via private message, email or over the telephone. You should expect to pay a fee to compensate the installer for their time, experience and help. If the technician chooses to help you for free, that is totally up to the technician. You can also send a PM or email to any of the moderator(s) of the forum in which you need assistance if additional assistance is needed. Again, you should expect to pay for any technical assistance offered."
