== Other considerations ==

A line code will typically reflect technical requirements of the [[transmission medium]], such as [[optical fiber]] or [[shielded twisted pair]]. These requirements are unique for each medium, because each one has different behavior related to interference, distortion, capacitance and loss of amplitude.<ref>{{Cite book|url=https://books.google.com/books?id=On_Hh23IXDUC&pg=PA284&lpg=PA284 |title=Network Dictionary |last=Dong |first=Jielin |date=2007 |publisher=Javvin Technologies Inc. |isbn=9781602670006 |language=en |page=284}}</ref><!--[[User:Kvng/RTH]]-->
