Do you think the original GSM equipment is still there?

It's has been progressively replaced/updated since it was installed,
and is still being replaced/upgraded today.

The CDMA equipment is/was still pretty much the same as was installed
10 years ago, and the upgrade path was a dead end.

Good luck.
