I have eight T1s going to my 7200 router at a call center. There are two hssi interfaces (70.50.16.55 and 70.50.16.59) supporting 4T1s each. I cannot ping one of the hssi interfaces (70.50.16.59) even though it shows up up. I'm able to ping it when I log into the other interface (70.50.16.55) and even able to log into the router through this interface (70.50.16.59) from the other one (70.50.16.55).However, once I'm logged into the interface I still can't ping it despite the fact that it shows up up. I cannot also ping the 70.50.16.59 hssi interface from my remote end. can anybody tell me what might be going on here? The call center is pretty new and this has been working for sometime. The T1s are connected to ADC kentrox boxes connected to these hssi interfaces. Thank you. Felix.
