Hi Everyone,

I just put an order in to ATT to change my ground start pbx trunk lines to loop start pots lines for our Mitel SX50 installed in 1994. I was reading on the forums and other websites how to change over the programming on the system and wanted to confirm the steps. I am a little confused how to get to register 2 so if someone could clarify that part. Previously I was told that I am using 4 trunks (573, 577, 579, and 580)

Here are the steps I think I need to do:
1. Hold Status
2. Enter password XXXX and let go of status
3. Enter 70
4. Enter the first trunk number I am using '573' push enter
5. Scroll over to register 2g and make this a '0' (my question is how do i get to '2g'. What is the difference between 1g and 2g? How do I scroll down to 2 and over to g?)
6. Push enter
6. Perform same steps for other 3 trunks.

If someone could confirm my above steps are exact that would be fantastic!
