Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'верхняя связь'. Use standard term 'канал связи (с восходящим трафиком)' or 'исходящий канал'.

Common Mistakes
- Using 'uplink' as a general synonym for 'upload' (which is the action, not the channel).
- Misspelling as 'up link' (should be one word or hyphenated: uplink/up-link).
