Specifically : EIA/TIA-232 gives a max speed of 115.2kbps over a 3.7M cable distance: http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a00801f5d8b.shtml X.21 gives a max speed of T1 (1.5Mbps) over a 15m distance: http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a00801f5d8f.shtml V.35 gives a max speed of T1 (1.5Mbps) over 15m as well: (and with a specific warning not to exceed 2Mbps (and the warning also applies to 449) http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a00801f5d8e.shtml I can't find any documents giving speed recommendations for EIA-530 at all. So, perhaps I should rephrase the question - what type of cable (and length) do people use to connect two ports running at 8Mbps when their choice is one of the options in a "5-in-1" cable? but my point was that none of these cables specifically says that it can handle an 8Mbps connect speed at any length.
