Usually, if the ESF light is lit, then the T1 is configured for Extended Super Frame (ISDN-PRI). If it's not lit, it is configured differently or there is a problem with the circuit. I just checked ours here and it's lit steady. A few weeks ago, our circuit went out a few times and each time, the ESF light was flickering. My guess would be that you definitely have a problem with the circuit from your service provider.
