Not much to discuss. The standards were designed with this eventuality
in mind, although it is contrary to contemporary 'best practice'.

Ethernet runs on pins 1,2,3,6. the center pair -- 4,5 -- is the standard
'pair 1', for telephony use.

Note: considerable care -will- have to be exercised in constructig the
'splitter', to maintain a quality 100mbit connection. Spec. requires
that you maintain the 'twist' in the pairs to within 1/2" of the connector.
