In a word - No. NEC 2002 para 800.52.A.1.c. states, "Communications
conductors shall not be placed in any raceway,..., or similar fitting with
conductors of electric light, power,...." There are exceptions but you
didn't list any that qualified. CAT 5 can be used for telephone so call
them the same in this instance. Telephone cable is still a communications
conductor even if it's POTS.
By running parallel to the electrical service you're setting yourself up for
induced power noise (aka power influence). Maintain at least 8 inches and
preferably 12 or greater from the power lines. Any time you cross power
lines try to do so at 90 degrees.
Now to get off the high horse. It has (running the cable in the same hole
and parallel to each other, and is being done on a daily basis by
electricians and security system installers. NEC 2002 para 300.3.C.1 allows
AC and DC circuits of 600 Volts nominal or less to occupy the same space.
Telephone and data are DC circuits right? At least that's the justification
being used. The 800.52 reference specifically states communications
conductors and at least in my opinion takes precedence, however check with
the authority having jurisdiction in your area.
I hope this helps.
