I'm no expert, but I'd imagine that any under-sea damage would be 
isolated to shallow approach to shore, and that the cable would be well 
below the wave action while the tsunami was in deep water. Cables are 
generally trenched pretty deep on the approach to shore as protection 
against dragging anchors, but I don't know what protection that would 
give against the undertow from a 10m-high wave.

I'd expect the most serious network damage to be in simple 
infrastructure above water (power, overhead cables).

Suresh is in Madras, I think. The BBC says Madras was "particularly 
badly hit".
