I spoke to someone from Airtel yesterday. He said that he was from the technical team & he seemed to know my area. The actual man on the ground, perhaps???Anyway, he said that they are upgrading 'the cards'. I never asked where but I am assuming that this might be at the DSLAM. I think he called the DSLAM the 'main pillar'. He said that the main pillar is less than 200 m away, but since I'm connected to a 'sub-pillar', I am limited to my current speed.He said that if you are not able to get faster speeds now, you might be able to in a few months, when the upgrade is completed..When I asked about FTTH, he said that it's not available in Chennai. I asked if it was coming, but he said that he had no idea.I do not know if this upgrade is pan India, but he claims that it's happening in Chennai. We'll come to know in a few months, I guess.
