Troubleshooting of PRI cards

Q1, You can not compile zaptel and asterisk

please make sure that:
1) You have installed all necessary packages and kernel source.
2) Make sure the version of kernel source is exactly same with the version of the kernel.
please check the few links:
http://wiki.openvox.cn/index.php/D110P
http://wiki.openvox.cn/index.php/D210P
http://wiki.openvox.cn/index.php/D410P
http://www.asteriskguru.com/tutorials/
3) make sure that you do not miss any packages or files in asterisk or zaptel.
4) make sure your system can access www.asterisk.org.
Q2, ZT_SPANCONFIG failed on span 1: Invalid argument (22)

please check:
1) run lspci -vvvvv, make sure the system can detect the card. Tiger jet chip will be found. If there is no such Tiger jet chip, please clean the PCI slot and try again.
2) if lspc can find the card, make sure the pci id is included in the PCI table in our driver. how to patch the picid, please refer this link:
http://www.openvox.cn/kb/entry/2/
3) if step 1 and step 2 are ok, please check the zaptel.conf or system.conf to make sure that the setting is correct.
4) if step 3 is correct, please make sure that there is no mISDN tiger jet module in the system, if it is there, please remove that or add to blacklist.
5) if you still can not boot it up, you have to recompile zaptel or dahdi again.
Q3, You can not make calls from asterisk

there are few reasons why you can not make calls:
1) check your extensions from your asterisk side, make sure your sip is ready to make calls, and SIP is with a right context what you put in extensions.conf
2) your pri is and active(leds are in green).
3) leds are up and card driver has boot up properly, but the zapata.conf is
, so asterisk does not boot up properly,
please check by run: zap show channels
please check the pri status, it MUST be up and active
if is empty or no such command, you should check your zapata.conf
4) Make sure dmesg shows without any error
5) Make sure the pri is up and active without any error
6) Make sure the physical connection is well established
7) You maybe recompile your zaptel and asterisk again.
Q4, How can you set the digital card for your country?

To set the pbx with your country support, you must:
1) set timezone and defaultzone to your country in zaptel.conf or system.conf of dahdi
2) set the country=your country in indication.conf
Q5, How can you open the debug for asterisk?

1) You can edit the file logger.conf under /etc/asterisk,
enable the debug or error, those message will be stored under
/var/log/asterisk
2) you also can start your asterisk in this way:
asterisk -vvvvvvvvgc -d
Q6, How can i check the IRQ of analog cards?

please run the command:
cat /proc/interrupts
you should see the IRQs, Make sure the card has OWN IRQ, Do NOT share with other devices.

Q11, When will the LED's light up on my TDM400P/TE110P/TE2XXP/TE4XXP?

For the TDM400P and TE110P cards, the LED's will not be lit up until the kernel module is loaded. The TDM400P LED's will light up when the ports are configured and the kernel module is loaded. They do not change if a phone or trunk is plugged in or not. The TE110P LED's will light up RED when the span is configured and kernel module is loaded. If configured correctly and a circuit or channel bank is connected the LED should turn GREEN.

For the TE2XXP/TE4XXP the LED's should scroll(knightrider) RED even without the kernel module being loaded or anything plugged in. When you have the spans properly configured and kernel module loaded without a circuit or channel bank the LED's should pulse RED. With the module loaded and a circuit/channel bank connected they should be solid GREEN. link from here:
http://kb.digium.com/entry/13/
Q12, Why is my card getting an IRQ miss?

Each peice of hardware takes 1,000 interrupts per second. When, for some reason the cards get less than this, an IRQ miss occurs. You can see if the card is missing interrupts using 'zttool.'

IRQ misses can cause different problems with Asterisk. Symptoms of IRQ misses are bad audio quality or perhaps PRI errors, although IRQ misses will not cause alarms. Also DTMF detection not working is something that can be caused by IRQ misses as well.

Several common things that contribute to IRQ misses are: -Running the X window system -Shared IRQs -No hard drive DMA -Hard drive DMA too high (shoot for udma3) -Running serial terminals or frame buffers

To check for shared IRQs you can run:

1. cat /proc/interrupts

CPU0

0 10756672 XT-PIC timer 2 0 XT-PIC cascade 5 10812879 XT-PIC uhci_hcd, uhci_hcd, wctdm 10 226219 XT-PIC t1xxp, CS46XX 11 1550046 XT-PIC eth0, nvidia 12 387234 XT-PIC i8042 14 32641 XT-PIC ide0 15 18 XT-PIC ide1 NMI 0 LOC 10757616 ERR 40481 MIS 0


Notice the T100P card sharing with the sound card, and the TDM400P card is sharing with the USB controller. This will most likely cause problems. If you are not using any USB devices that would probably be ok, but it would be best to disable USB or get the card on it's own IRQ.

There are several ways to move cards to their own IRQ.

-Turn on APIC
-Tweak BIOS settings
-Try a different PCI slot
-Use setpci

Q13, Why am I having DTMF detection problems?

Zaptel DTMF Detection Problems
DTMF detection problems can be caused by a number of different factors. The most common is running the X Windows System. Another cause of DTMF detection problems is the relaxdtmf option in Zapata.conf. It may need to be turned on or off. If you need to force all DTMF detection to be done in software, you can set vpmdtmf support to 0 in wct4xxp.c and recompile, or you can specify it as a kernel module option at runtime.

SIP DTMF Detection Problems
If you are having problems sending DTMF digits amd are using a SIP phone, make sure the dtmfmode they have set is the same on the phone and in Asterisk. Also make sure you are not sending both inband and out-of-band (rfc2833) tones.
Q14, I am getting error messages about PCI Master Aborts. What is wrong?

This is a very rare case. When your computer's PCI subsystem experiences serious problems with OpenVox's cards upon initialization of the card, Linux will print out scrolling "PCI Master Abort" messages. What you should do is go into your system's BIOS, and turn off your motherboard's PNP (plug and play) feature. If this does not resolve your issue, You should contact OpenVox support.

Q42, Why are you unable to call out with Asterisk 1.4.22?

If you are using wctdm or opvxa1200 with Zaptel and Asterisk 1.4.22 then there is a known issue with outbound calls. The reason you are not able to call out is because Asterisk 1.4.22 has a new feature which detects if a analog line is plugged in or not, but this feature only works with Dahdi. So to fix the issue you can do one of the following.
edit the file under /asterisk-1.4.22、channels/chan_dahdi.c" find this line

1. ifdef DAHDI_CHECK_HOOKSTATE return 0;
2. else return 1;

Change the "0" to a "1"

1. ifdef DAHDI_CHECK_HOOKSTATE return 1;
2. else return 1;

Q43, Missing libpri

Symptom: chan_zap fails to load (no 'zap' in the CLI). In the logs you see the error:

chan_zap.c: Unknown signalling method 'pri_cpe'

Cause: chan_zap.so in Asterisk was built without support for libpri. libpri was not installed when you ran ./configure before building asterisk.

Fix: Rebuild asterisk and make sure libpri is supported.

$ strings channels/chan_zap.so | grep pri_cpe
pri_cpe

Q45, How to get more debug information

under asterisk console, run : pri intense debug span X, X is span number
Q46, T1/E1 Clock Synchronization

TE1 Clock synchronization is used to propagate a single clock source over the T1/E1 ports on a single card.
Before configuring your system you must identify which ports should be in NORMAL (slave) clock mode and which should be in MASTER clock mode.
All ports connected to TELCO MUST be in NORMAL mode,
because Telco is ALWAYS MASTER clock.
Example:
zaptel->Port 1 connected to TELCO // port 1 MUST be Normal(slave) clock mode
zaptel->Port 2 connected to channel bank or back to back to another T1/E1
device. In this scenario Port2 must be configured as CLOCK MASTER.

Q52, chan_zap.c:7874 pri_dchannel: PRI got event: HDLC Abort (6) on Primary D-channel of span 1

If you are being flooded (several times a second, non stop and the pri never worked) by lines as:
Jul 14 13:55:21 NOTICE[19519]: chan_zap.c:7874 pri_dchannel: PRI got event: HDLC Abort (6) on Primary D-channel of span 1
Then probably the PRI you are using is not using PRI signalling but maybe some other type of signalling like E&M.

Q57, How do I run a pattern loopback test (patlooptest) on my E1/T1 card?

OpenVox's pri cards can be tested using patlooptest. This test transmits a bit pattern and listens for the same bit pattern to be received, comparing the results. To run the test, plug an E1/T1 loopback cable into the port to be tested. here, the pin assignment of lookback cable is 1->4, 2->5. this is a example for how to make a lookback cable:
http://www.ortizonline.com/publications/april2004/loopback.htm

1. With the system powered off, confirm that the board jumpers are set appropriately for E1 mode or T1 mode. (Refer to the user's manual for the interface card.)

2. Use zttool (or dahdi_tool) to confirm that the span is "OK" (green alarm):

zttool

or

dahdi_tool

3. Make a backup of /etc/zaptel.conf (or /etc/dahdi/system.conf).

4. Configure the span(s) as follows.

For E1 mode, /etc/zaptel.conf (or /etc/dahdi/system.conf) should contain:

span=1,0,0,ccs,hdb3,crc4
clear=1-31
# for TE2xx and TE4xx, uncomment the following two lines
# span=2,0,0,ccs,hdb3,crc4
# clear=32-62
# for TE4xx, uncomment the following four lines
# span=3,0,0,ccs,hdb3,crc4
# clear=63-93
# span=4,0,0,ccs,hdb3,crc4
# clear=94-124

For T1 mode, /etc/zaptel.conf (or /etc/dahdi/system.conf) should contain:

span=1,0,0,esf,b8zs
clear=1-24
# for TE2xx and TE4xx, uncomment the following two lines
# span=2,0,0,esf,b8zs
# clear=25-48
# for TE4xx, uncomment the following four lines
# span=3,0,0,esf,b8zs
# clear=49-72
# span=4,0,0,esf,b8zs
# clear=73-96

5. Use ztcfg (or dahdi_cfg) to configure the channels:

ztcfg -vvv

or

dahdi_cfg -vvv

6. Make the tests, including patlooptest:

cd /usr/src/zaptel/
make tests

or

cd /usr/src/dahdi-linux-complete-N.N.N+N.N.N/tools/
make tests

7. Run patlooptest:

./patlooptest /dev/zap/1 300
Going for it...

or

./patlooptest /dev/dahdi/1 300
Going for it...

(To run patlooptest on each of four E1 spans:

./patlooptest /dev/zap/1 300
./patlooptest /dev/zap/32 300
./patlooptest /dev/zap/63 300
./patlooptest /dev/zap/94 300

or

./patlooptest /dev/dahdi/1 300
./patlooptest /dev/dahdi/32 300
./patlooptest /dev/dahdi/63 300
./patlooptest /dev/dahdi/94 300

To run patlooptest on each of four T1 spans:

./patlooptest /dev/zap/1 300
./patlooptest /dev/zap/25 300
./patlooptest /dev/zap/49 300
./patlooptest /dev/zap/73 300

or

./patlooptest /dev/dahdi/1 300
./patlooptest /dev/dahdi/25 300
./patlooptest /dev/dahdi/49 300
./patlooptest /dev/dahdi/73 300

)

The first parameter to patlooptest is the channel on which to run the test (e.g., /dev/zap/1 or /dev/dahdi/1 ). The test should be run on the first channel of the span in question.

The second parameter is an optional timeout (e.g., 300), measured in seconds.

patlooptest should complete without displaying any errors. If there are errors, it may indicate that the card or port is bad. However, errors could also be caused by interrupt misses or a faulty loopback plug.

If patlooptest does not terminate after the timeout interval, then the card is probably not taking any interrupts.

7) edit extensions.conf：

extensions.conf
[ss7_call]
exten => 100,1,Dial(ss7/outgoing number)
exten => 100,2,Hangup

8) Load zaptel, wct4xxp and start asterisk

modprobe zaptel ; load zaptel
modprobe wct4xxp ; load the wct4xxp
ztcfg -vvvvvvv ; load the channels
asterisk -vvvvvvvgc ; start asterisk

Under asterisk console

CLI> ss7 link status ；Check the status, make sure there is no error.
; 检查 ss7 的状态， 确保没有异常。
linkset ls1, link l1, schannel 16, sls 0, INSERVICE, rx: 5, tx: 1/3, sentseq/lastack: 4/4, total 199328, 199424
CLI> ss7 status

Q59, How do I change the type of line from E1 to T1/J1 without using jumpers?

If you do not have physcial access to the card, and you need to set it in T1 or E1 mode you can pass a special option when loading the module to accomplish this task:

insmod wct4xxp t1e1override=0xFF

This will set all four spans into E1 mode.

insmod wct4xxp t1e1override=0x00

This will set all four spans into T1 mode.

If you need some spans T1 and some E1 use the following guidelines.

The settings of the spans must be passed as a bitmask in the module paramater. To create the bitmask use the table below adding the value of the numbers corrisponding to the spans you wish to enable. span value 1 1 2 2 3 4 4 8

So to enable spans 1 and 4 you would call modprobe like so:

modprobe wct4xxp t1e1override=0x09

As you can see I added 1 and 8 to get 9. Remember if you pass this value in HEX to format it properly.

To make spans 1, 2, and 4 E1 spans, you would use the following parameter:

... t1e1override=0x0B or ... t1e1override=11

Q60 To get the quick support, what information about the system I should send?

* Versions of kernel and Linux distribution
* Versions of asterisk and zaptel/dahdi
* Model of OpenVox products
* Debug and error information from your system and asterisk
* Zaptel(zaptel.conf and zapata.conf) or dahdi (system.conf and chan_dahdi.conf) configuration files and extension.conf if your have trouble with dialplan
* After loading the driver, run the command: demsg and send the information to us
* Output of the command: cat /proc/interrupts
* Message in asterisk console when you making a call, if you have trouble to drop/receive calls.
* Protocols you want to use(FXS,FXO,PRI..)
* Ssh account with root permission if you need us to check the system.
* Make a backup for your important files
* Describe the problem in details
* Serial numbers of OpenVox's products
