Business telephone system article needs more interesting information This article would be better identified as "Key Telephone Systems" or "Small Business Telephone Systems", since it does not address PBXs (which are described in their own article). The following points should be made clear:-
Merging Private branch exchange into this article is complete, although there is cleanup remaining to be done. For anyone coming here wondering what happened, there was enough overlap that this article, which used to be the "key system" article until a rename changed it's scope, and the "private branch exchange" article were WP:BOLDly merged into this article. Remaining tasks are:
I'll try to continue this effort tomorrow, but if you feel like working on any of the above, please do so :) Triona (talk) 09:38, 5 September 2010 (UTC)

A business telephone system is any of a range of a multiline telephone systems typically used in business environments, encompassing systems ranging from small key systems to large scale private branch. A business telephone system differs from simply using a telephone with multiple lines in that the lines used are accessible from multiple telephones, or "stations" in the system, and that such a system often provides additional features related to call handling. Business telephone systems are often broadly classified into "key systems", "hybrid systems", and "private branch exchanges".® — Preceding unsigned comment added by 203.105.170.131 (talk) 09:09, 7 August 2013 (UTC)
I believe that PBX(Private Branch Exchange) or PABX is the common name in the field instead of the Business telephone system(BTS?), Can change the subject of the topic and redirect it to the common name? Goodtiming8871 (talk) 23:38, 16 July 2018 (UTC)
I am planning to replace the subject from "Business Telephone System" to "Private Branch Exchange(PBX)" and redirect the old name to the common name in about one month if there is any objection about changing the topic as PBX is the common name for phone exchange. I think the current trend is the mobile phone generation so the interest in the landline phone system might be not as widespread with mobile technology. Please let me know your feedback if possible. However, I think that IP PBX should be the separate topic with this as it is the next generation of the PBX Goodtiming8871 (talk) 01:41, 26 July 2018 (UTC)
Hi, :@Danhash: Thank you for your valuable recommendation. It would be sensible for keeping the PBX as the main topic. Would you be able to clarify the abbreviation of IMO? Goodtiming8871 (talk) 00:10, 27 July 2018 (UTC)
"Primary rate interface (ISDN) – Provided over T1 (23 bearer channels and 1 signaling channel) or E1 carriers." - 23 bearer channels is purely US-(and possibly Japanese) Standard! Primariy rate in Europe is and was for the past 30 years 30 (thirty) channels plus 1 signalling channel! 80.151.9.187 (talk) —Preceding undated comment added 14:05, 10 January 2019 (UTC)
