Have tried this article? Question Total Control HiPer DSP - DSO's intermittently go into LOOS Incorrect modem command (AT%R) settings written into T1/E1 span settings Answer Please take on of the following actions: 1. After flash updating code and rebooting HiPer DSP card, default the T1/E1 settings from factory default within TCM. Configure span per telco requirements then save configuration again into NVRAM. Or 2. Log into HiPer DSP console either via reverse telnet from gateway card or serial connection and enter the following commands: chdev mdm 255 <Enter> at%r1=3%r2=10%r3=1%r4=3%r5=2%r6=1&r7=4&w <Enter> wait for "OK" prompt. If none seen enter ATE1V1Q0 <Enter> and repeat above command at%r? <Enter> display should read - Per-R parameters 1:3 2:10 3:1 4:3 5:2 6:1 7:4 chdev span <Enter> cmd sinserv <Enter> dis ats <Enter> (all DSO's should now be idle) cmd svspcfg <Enter> -----Original Message----- From: usr-tc-bounces+adam=semo.net@mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Joel - Fox Computers Sent: Thursday, July 15, 2004 12:29 PM To: Discussion relating to the 3Com/US Robotics Total Control modemsystems. Subject: [USR-TC] DSP Out of Service Problem Importance: High Got a wierd problem I hope someone can help with. The chassis has 2 Hiper ARCs (5.3.110) and 6 Hiper DSPs (3.5.109). We're running PRI's to them. The Hiper ARC "list chassis" shows the correct cards, the ARC in slot 15 owns all the DSPs, the ARC in slot 16 owns nothing. NMC Chassis Awareness is disabled on both Hiper ARCs, they are set up statically. On a DSP with no PRI plugged in, I see something like "DS0 Timeslot Idle", whatever is normal. With a PRI plugged in, after a hardware reset on the DSP, you see the same thing. Then somewhere between 5 and 60 seconds after the reset, the status goes to "DS0 Local Out of Service" on all the timeslots. The DSPs have been reset to factory Defaults, with the only change being the Switch Type, which is set to NI2, of course followed by saving the setting and resetting the card. I know this setting is correct, I can unplug the PRI from the DSP card and plug it into a PortMaster (which is configured for a plain PRI with NI2 as the switch) and it links up and takes calls right away. I'm reasonable certain it's not the Hiper ARC, because we did at one point have half the DSPs owned by each ARC and had the same result. Pulling my hair out over this one - any suggestions? Any idea what I'm overlooking or not checking? Any suggestion would be appreciated.
