7550e Codeplug File Type

We got radios at work. I asked the Vendor for the codeplug and he sent me 3 files.

*.ctb
*.cno
*.tfn

What are the CNO and TFN files? The ctb codeplug he sent doesn't really reflect the radio I have so I plan to read the radio at home with my CPS software. I'm trying to program features of the radio that they left off since they programmed the radios without asking me for some of the details of what we want. Instead of trying to send them all back, I can do it myself since there are only 15, but I'm not sure what those files pertain to.

cno is a Connect Plus codeplug and tfn is a Connect Plus frequency file.

cno is a Connect Plus codeplug and tfn is a Connect Plus frequency file.

Thanks Mike. I've never seen either of these before, do they open in the CPS?

Ok thanks. If I wanted to program zones in the radios for simplex use intra-site, where can I find out which frequencies I can program into the radios?

If your organization has a license for frequencies, then use those. If they don't, then whoever owns the radio system may be willing to allow you to use some of their simplex frequencies. Do not use trunking system inputs or outputs for simplex. TT

Thanks for the advice. We do not have a license. I talked to the vendor and they don't actually have to send the radios to another city, they have a tech(s) here in my city. I'll just work with them to reprogram.

Thanks
