 RJ45 Cabling
recently We designed a voice/data cabling Project for our clients. Project provided the use of standard tele/data outlets with (4) RJ45 jacks. According to TIA/EIA 568A Standards, these outlet should be wired with (1) voice and (3) data cables. so total of four cables. Recently we got a call for Cabling Contractor, which claims, that we have calculated too much cabel runs, because there will be used only one data and one voice outlet per workstation. From his point of view he is right, so is there any guide, to use for cable quantities calculations?
Thank You for your time.
Sincerely, Anzor Natli

Dear Anzor,

here is a phrase from the TIA/568-A standard (page 20, part 4.5 "Choosing media"):

"A minimum of two telecommunications outlet/connectors shall be provided for each individual work area .... (it is not necessary that they be on separate faceplates). One telecommunications outlet/connector may be associated with voice and the other with data. Consideration should be given to install additional outlets/connectors based on present and projected needs"

Hope it answers your question.

Best regards
