Team positioning
The mere sight of a five-stock Cable is enough to make even the most advanced players break into a sweat, so a classic tactic is running a strong battery like Storm or Spiral then bringing in Cable. His assists are also decent, but he likes having an assist himself for mixups and defense since he struggles in those areas somewhat.
Point
Cable is a strong zoner on point, having a full complement of both assists to boost his zoning allows him to go for traps and force the opponent into getting chipped or taking a risk of getting shot. Main downside if he is starting of course is that he will not immediately have meter to do multiple supers at once.
Mid
A good position for Cable because he will come in with more meter and is also a dhc target. His Alpha counter is available as well.
Anchor
If you don't have another Anti-air assist, you'll probably have Cable in the back. He's likely to come in with 3+ bars, making him dangerous. Alpha counter or tag is always a threat too. Your opponent is very likely to attempt to snap Cable in if you have only 1 or 2 meters.
