Hello, We are in dire need of some assistance in configuring our HiperDSP cards with Netservers. Here is the issue. Our Telco is using AT&T 5ESS Switches in NI2 mode. We have 3 HiperDSPs 8mb dram/2mb flash(v.3.5.12) with 1 Netserver 16mb dram/4mb flash(v.3.8.1) and HiperNMC 16mb dram/flash(v.8.6.3) We have been unsuccessful in establishing more than 1 HiperDSP getting it functional with our Telco. The first DSP hands all calls without any problems however when it starts to go to the next PRI span however, the line picks up and then hangs up immediately. Our telco is saying that our equipment is doing this. We have tried rebuilding our circuit from scratch and still the last 2 DSPs just drop the calls. I have the startslot set to 1 with the 3 DSPs in the first 3 slots. Slot 4 is the Netserver. All 72 modems are Active, Ready and waiting for calls in the Netserver. Anyone experienced such a problem? Any solution to fixing this? If anyone can assist, I would greatly appreciate it. Thank you Rudy K.
