I have a client with a D-Link isdn router. We set him up to dial our Total control box. B1 comes up fine, when they start pushing alot of data, B2 comes up fine. Throughput increases approiately. When the demand on the line drops off, the B2 channel will turn off. At that time, they stop passing all traffic. Any idea why everything quits when the B2 disconnects? my codes: DSP 2.0.81 HARC 4.2.32 Note: On the client setup, i made their default gateway two hops away. I have two harcs, when they connect it might go to either one. So i made the Dlink default gateway to the Cisco, one hop upstream from the usr-tc.
