Solved: DSP Issue on 2801 router

olusegun.rufai · ‎02-17-2013

Hello, i have being trying to troubleshoot why incoming calls and outgoing calls to the PSTN is not working on a 2801 router after configuring it to do. Along the line discovered that my FXO ports were just showing amber even after when the router has booted up. Very new to Cisco VOIP but was able to do the following show comands, that's when I realized this could possibly be a DSP issue but don't know how resolve this. Will appreciate if someone could help me out based on this. Here are the output of the show commands I ran:-

Hi

Check your flash to see if you have a dsp_c5510_flex.rbf file on there - if you do rename it to something else or tftp a copy off and delete it. The DSP should then get the firmware that comes with the IOS version you run.

Hello Aaron, i checked on the router's flash and the file is not there, what i now did is to copy the file from one the froum on this blog ans installed it on the router and rebooted but the problem still persist. Could this be a faulty PVDM or if i do an IOS upgrade the problem will be solved.

Ayodeji Okanlawon · ‎02-18-2013

Segun,

You can use the following to test the state of the dsp..my guess the dsp showing a status of bad is faulty and you will have to replace the whole PVDM

MAN_VG#test voice driver
Enter VPM or HDV or ATM AIM or NM-HD-xx or HDV2 slot number : 0

C2800 Debugging Section;

1 - FPGA Registers Read/Write
2 - 5510 DSP test
3 - DSPRM test
4 - HDLC32 test
5 - Quit

Select option : 2

5510 DSP Testing Section:

1 - Reset ALL DSPs
2 - Reset 1 DSP
3 - Download DSPware
4 - CHPIR Enable/Disable
5 - Display c5510 ring
6 - Show HPI RAM
7 - Show eHPI memory thru Relay command
8 - Show Controller
9 - c5510 Keepalive Enable/Disable
10 - Download bootloader using indirect slave access
11 - Write HPI RAM
13 - DSP application download
14 - faked dsp crash
15 - Wait in Firmware Restart Indication
16 - Display DSP Keepalive Status
17 - QUIT

Select option : 16

DSP Keepalive Status Display:------------------you should see an output like this.
=============================
DSP 1 is Alive, State: 4, Keepalive Sent: 327216, Skip 566572
DSP 2 is not UP, State: 5, Keepalive Sent: 0, Skip 0-------------------------------DSP2 was faulty in my case.
DSP 3 is Alive, State: 4, Keepalive Sent: 417410, Skip 476382
DSP 4 Not Exist

You can try and reset the DSP and see if it helps, otherwise I am afraid you may have to change the PVDM

Hi aokanlawon

Could you please tell me the complete procedure to upgrade the firmware on the DSP Chip and were to download it from ?.

For learning purpose i tried the above command "test voice driver" but it is not availble on my 29XX Series router.

Thanks.

Ayodeji Okanlawon · ‎02-18-2013

There are two ways to upgrade the dspware (the firmware on the dsp)

1. Upgrade your IOS, becaue dspware is embedded in the IOS

2. Send an email to TAC to get you the required dspware, this will upgrade your dspware regardless of the IOS version you are running

TAC will send you a file to copy to flash. For the C5510 dsp (on most 2800 routers) they will send you a file called dsp_c5510_flex.rbf, which need to be specific for the DSPs that are in the router. Once copied to flash, reboot the router and it will look for these files and use them. Otherwise, it will use the DSPware version that is embedded within the IOS.

The test voice driver will not work for the 2900 routers because they use a different DSPs to the 2800 routers. From the output of that command you can see that the command is for the C5510 dsps.

The 2900 uses dsp type SP2600.

Hello Brov, i already did the test immediately i discovered the issue, its actually in my very first post but here it is again:-

Lastly did a voice test driver:-

DSP Keepalive Status Display:

=============================

DSP 1 is not UP, State: 5, Keepalive Sent: 0, Skip 0

DSP 2 Not Exist

DSP 3 Not Exist

DSP 4 Not Exist

DSP 5 Not Exist

DSP 6 Not Exist

DSP 7 Not Exist

DSP 8 Not Exist

And also reset the DSP which still didnt make the DSP come up, so i guess i will have to replace the PVDM?

Thanks alot.

Ayodeji Okanlawon · ‎02-19-2013

Segun,

Sorry I missed that. Yes you will have to replace it. You can do an RMA if you have a valid service contract.

Hello Okanlawon, how is work going? Thanks for your support the last time

Now I have been able to purchase a new pvdm and installed it and I did

the following commands to test if the DSP is working fine now. Please

find below the output of the test.

Now I have made calls from the PSTN to the phone line which is

allocate the dsp resources for transcoding. Because from the Show

voice dsp detailed its showing dsp not allocated and idle.

Thanks inadvance

Ayodeji Okanlawon · ‎04-14-2013

Segun,

OK..So is it only ringing you dont get? does the call connect? In this call setup you dont need any transcoder..Your DSP will encode your G729 codec coming from your ephones to the 64Kbps PCM used by the PSTN.

Ca you send

Hello Brov. I configured the wrong plar extension, swapped it for another DN instead of the FrontDesk extenstion. Thanks alot, Really appreciate
