This document explains what an Item 21 Attachment should contain, details the acceptable methods for submission, and provides sample attachment formats for:
- outlining Telecommunications, Internet Access, and Internal Connections services
- describing ineligible functionality
- using representative bills
- amortizing large installation charges
- justifying on-premise Priority 1 services
- certifying non-use of remote access services.

If you want your application to sail through the PIA process, I suggest you model your Item 21 attachments after these examples for Year 6.
