HFC Foundations & Hardline Craft
Reading Plant Design Maps (AM975 Example)
Use PDF design prints to find node identity, power supplies, active amp tables, EOL tags, tap values, and street routing — then reconcile what you see in the field before cut-outs or amp work.

Objectives
- Locate node ID, PID, and power supply designators on a coax design print
- Read the actives table: amp labels, models, pads/EQs, DLA, voltage, and current
- Interpret EOL (end-of-line) tags and tap values along feeder and laterals
- Apply design notes such as rebalance-after-upgrade before changing pads
- Cross-check Smartsheet / job package map revision against the PDF in your tablet
- Plan a field visit from map data without relying on tribal strand memory

What a Coax Design Print Contains
Maps Are the Job Package
PDF design maps (often exported from GIS or design tools) are the authoritative layout for node boundaries, hardline routes, tap values, and active device settings. Field evolution projects expect you to work from the current map revision — not an old screenshot in a group chat.
Before you open a housing or cut hardline, confirm you are on the correct node and active label (A1, A2, …). A wrong amp label wastes alignment time and can violate node health rules when EOL sweep scope is tied to tap loading.
AM975 print — header fields (example node)
- Node
- AM975 — your field node designator on the print title block
- PID / project
- 4427518 — ties traces and Smartsheet rows to this evolution job
- Power
- AM975A — 90 VAC supply location on map; verify lid label matches
- Actives
- A1–A8 — inline labels matching housings on strand
- EOL
- E1–E16 — end-of-line test points; drive sweep/OneCheck scope
- Streets
- Cherokee Dr, Miami Pkwy, etc. — reconcile driving directions to map geometry

Charter evolution workflow marks nodes actively being worked with a paperclip icon. Update Smartsheet in real time when you start or finish an active so the next crew does not duplicate alignment or cut-outs.
