Not to start another discussions, but just to update one. What was ever resolved about a "pair of modems" (re port) in the hiperdsp's getting stuck in a mode that would not answer and would send out strange connection tones when dialed. The stuck modem would require the board to be reset to fix the situation. Was this determined to be in hardware or in software? Is there a version of hardware/software that is better/best? Was there a fix to prevent it from re-occuring? ---------------------------------------------------------- In the knowledge base, using "dsp modem not answering stuck" for a search key, I get 18 solutions: (Total search time 2.4 hours on a T1) 1. Upgrade HiPer ARC to 5.0.84-1 or newer code. I have 6.2.17 2. This message means that 1 of the DSP chips is not responding to the keep alive messages from the RISC. This is probably caused by a hardware failure. Reseat the DSP NIC and NAC and try a different slot. If the modem still shows the same reason for call failure,the DSP card must be replaced It happens on dsp hardware 49, 53,and 54, randomly. Do I need to replace all the cards as they happen? 3. This is fixed in HiPer DSP V2.0.60 I have 2.0.19 4. did not apply, ring no answer or busy on dsp 5. If during the AutoDetect Dialout sequence the switch responds with a Release Complete (Cause code 57), the HiPer DSP aborts the dialout attempt, and does not follow the *Ux settings. Fix 3Com is currently investigating this issue. Please refer to Technical Support for more information as it becomes available. (August 1999 answer) 6. install cards 7. reset cards 8.
