The exchange file what defines your cell's coverage. It is what you and the administrator of your zone must share in order to make sure you agree about your cell's coverage. Initially, you must prepare this file and send it to tpcadmin (or your zone administrator) to begin the registration proceess. After that you must maintain it, keeping it current and sending updates to your zone administrator as you change it. Since the exchange file is fed to a few scripts here on our end in order to get you set up, it much adhere to a very strict format. Getting that format correct the first time will save us all a lot of energy ;-) Comments are denoted by a '!', and must contain as much detail as possible about your cell, including the hostname of the server and contact information should we ever need to reach you. In its most basic form, a typical exchange file would look like:
! Wibble Communications
! 1234 #5 Some Street
! Some Place, Some State, USA 32000
! phone: (123)456-7890

But what if you wish to cover an entire exchange, not just a subset of prefixes within that exchange? Easy! Complete coverage of the '123' exchange would be represented by
! This next line registers us for all of +1-123
zone_name!123!*
What if you only want to cover a few specific number? You could specify them explicity, using a '.', as follows
My two home numbers!123!1234567. 1234555.
And finally, what if I cover a cell that is also covered by another site, AND I want to make sure some specific fax numbers (mine) are always routed to my fax server? Easy, list those numbers explicitly as well as with your general area coverage.
SecureDesign!5036903037. 5036901819.
