Talk:Trunking

From Wikipedia, the free encyclopedia

I'm trying to put together a reference to trunking in regards to ethernet networks, but I'm having a hard time figuring out how to integrate it into this article and not introduce confusion, since traditional circuit-switched telecommunications and packet-switched ethernet networking use terms like "switch" and "trunk" differently.

Ethernet port trunking likely best floating off on its own as a separate topic, with a reference to it on this page.

I'm not sure which trunking definition is more popular in terms of common usage. Certainly the circuit-switched definition is older, but it seems to be falling out of use in favor of packet-switched network terminology, as VoIP and broadband takes over as major telecomm services vs basic phone service.

[edit] Trunk Line

Trunk line redirects here, but the article doesn't mention it. This is unfortunate. Harley peters 06:02, 14 November 2006 (UTC)


[edit] Accuracy

A T1 has 24 channels, each of which can carry a voice signal, or be combined to improve data bandwidth. ( With an IVAD ) Each channel is known as a trunk, while the T1 itself is a trunk group. Also, a DS3 is 28 T1s, and again, each individual channel would be a tunk, and each T1 would be a trunk group.

While VOIP may change this in future, its time has not yet arrived. Most telecommunications around the world, even in rich countries, is not performed using VOIP.

[edit] Derivation Rework

The 'Derivation' section is utterly confusing. It is not at all clear whether the origins of the term come from the road, the railroad, the trunk of an elephant, or a tree trunk. If they are alternate and competing theories, this should be made clear. I take it that the origins of the term are unclear and the four options are just theories. Is this so? If I don't get a response to my comment, I will go ahead and modify the section to express this ambiguity rather than leave the reader wondering. Montblanc2000 21:37, 23 June 2007 (UTC)

Yes, please do. The mess is partly my fault. Jim.henderson 03:29, 24 June 2007 (UTC)


This article needs some attention, I think.

[edit] Radio Communication

This par hardly does the subject justice. Rather than expand it I think it should

be replaced by - See Trunked radio system

[edit] Telecommunications

should be followed by a sub-heading - Trunk, to cover the next par. Additional definitions could be added here to cover some of the other usages of

the word.

[edit] Trunk Line

This par should be expanded to cover differences in usage over the last 100+ years, and between the two sides of the Atlantic.

[edit] Telephone Exchange

This heading should be changed to - Trunking. The reference to grading should be deleted or qualified, as there were/are plenty of trunking systems that didn't/don't use grading.

[edit] Derivation

The elephant trunk theory is cute, but I think it's probably an urban myth. There are plenty of analogous usages - arteries, canals, roads, railways - all of which are derived from the tree/branch idea. I personally favour the railways analogy. UK practice tends towards 'trunk' (long distance) and 'junction' (local) lines, which could match up to railway usage, although 'main' and 'branch' lines are more common, these days, in that area.

[edit] Sections

Hey, I think that radio and telephone trunking is far more common than ethernet trunking. I'm going to change the order of the sections to reflect that, especially since telephones and radios have been doing it before the personal computer was even invented. I think even if you make a separate article, this one needs to have some reference to ethernet, but it shouldn't be the first case. --Kraftlos (talk) 18:39, 7 May 2008 (UTC)
