One way transmission

[GregL123]

Hi there,

I am working on an option 11c/cs1000. It Has 3 cabinets that are chasis style and 1 cabinet that is an option 11 cabinet. Software is 4.5. Cabinets are connected through fibre. Each cabinet has a ssc card in it instead of a fibre receiver card in it that the fibre connects to.

The problem reported is: while users are on the phone, (was given 5 extensions - not sure if it's happening to all) and all of the sudden there is one way transmission. ie - Callers can hear them but they cannot hear the caller.

The phones that I was given are all 3904 sets. There are no IP sets on the system. So I figured maybe its related to the firmware. And I know that 3900 series phones can be quirky if they don't have the firmware updated etc. So I checked the firmware of the switch. It's at 89. Checked the phones and they are also at firmware version 89. So the phones didn't need it because they were at the same level as the switch but I performed a firmware download to the phones given anyway in hopes that this will solve the issue. However, Im not very optomistic.

Pri's look ok. No slips. Nothing in the history log looks unusual as far as I can tell.

Any suggestions as to what this might be? I was told that maybe it might be the tmdi's? and to down them and then when upping them, then do a force download to the tmdi? Failing that I was told it's probably the telco. Which the customer has already reported but said there was no trouble of course! lol.

Suggestions?

Thank you in advance

Greg.

Are you sure it is an SSC card in each of the SLOT 0 positions? If you have a CS1000E then they are MGC cards and they should be connected via the Ethernet connections. If you get one-way speech path, you may have a DSP issue on the MGC cards.

So first check the Slot 0 Cards and make sure what they are. I don't see an SSC card in each slot, unless they are fiber/IP cabinets, then you need to check to see if you get any QOS errors.

If they turn out to be MGC cards then you may need to reset your MGC cards.

Check the system type:

If it looks like this then you have IP Expansion cabinets and not Fiber Expansion. Release/Issue are for this test system and your's will show your release and issue. Then you can go to:

If you that this type of set up, then you do NOT have MGC cards, but SSC cards with IP expansion cabinets. Check for QOS issues and may need to reset the SSC cards to clear this up. One-way transmission is a bugger to figure out.


Hope this helps a little.

1000S system most likely, you can check the fiber, loop back (forget load...135?) to test, stat them etc.

but it could be a digital line card, see if the users that are complaining seem to be on the same digital line card (some of those 1000s systems had the 48 port cards in slot 4 of the main chassis, not the expander)

Thank you for the reply Jenaya,

Yes they are definately SSC cards in each cabinet. Originally that's what I thought about the issue as well. Ie - DSP's, MGC cards. But that's not the case. They are definately SSC cards in the slots connected by Fibre.

Thank you anyway though!

Greg.

 

[GregL123]

Thank you for the reply Triton101!

They have moved the phones that were mentioned to the other Digital line card in another cabinet. Same problem exists.

I was wondering... I've heard that in the past with the option 11c PBX's, as with pc's, if weird quirky things start happening, give it a reboot. ie - power on and off. Fixes things! lol.

Any thoughts? I think this should be tried before starting to replace parts?

Thanks for the respsonses guys! Greatly appreciated!

Greg.

 

[Triton101]

Well, if you eliminated the cabinet / card, and the issue exists in SET to SET calls, then it's possible (your thinking of reboot), you might get it fixed with an INI or reboot.... but unless you can track the calls, it's hard to tell if you have a hardware issue or software.

but if this one way issue only happens on PRI calls, then it might be the TELCO.

Ok, soo... the reboot did not help! Happened again today.

Anything else?

Fibre/Ip daughterboards on the SSC cards to be replaced? Inclined to think it's the fibre daughter boards that need to be replaced. But, without downing the system and pulling out the card, what command/commands can I use to see if it has fibre daughterboards or IP daughterboards. I've found stat fil for fibre boards and stat ipr and ipm for daughterboards (see below). Now Im doubting myself because I see IP daughterboard information on power up, but, fibre cabline coming out of each ssc card is throwing me off! and if I do replace Fibre/IP daughterboards, replace them all? ie each cabinet's or just start with the one in the main cabinet?. Are the chasis at least not connected by a copper cable that runs from the back of one cabinet to the back of another/epansion chasis? (obviously not the cabinet).

Actually come to think of it... looking at the power up, seeing this....Dual ethernet expansion board #1 installed.
IP DB MAC address 1: 00:90:CF:06:3B:F2
IP DB MAC address 2: 00:90:CF:06:3B:F3" makes me think it's IP Daughter boards. But like I said, the fibre coming out of each ssc card is throwing me.

Anyway see below.

Hello,

Logged in this morning and listed the history file. Wondering if it's Fibre/IP daugherboard issue? Reason being is because, would I not see errors indicating problems? Don't see anything in the history file. But, what I did see was clocking messages? Was wondering if it's possible clocking issue?

Here's what I saw yesterday when I heard they were having problems. I didn't get the message until 1:52pm that the problem happened again but the error's/clocking issues shows around 12pm.

Here's what the clocking is at:

.ssck 0
ENBL
CLOCK ACTIVE
CLOCK CONTROLLER - LOCKED TO SLOT 1
PREF - 1
SREF - 2
AUTO SWREF CLK - ENBL

IP DB PORT 3 DSBL
IP DB PORT 4 DSBL

And here's the error's around 12pm below.

Wondering if this might be the issue? Or am I barking up the wrong tree?


Anyway, just thought I'd add this info.

Thanks

Greg.

 

[GregL123]

Another thought... Should I change the clocking to Free Run?

Thanks

Greg.

 

[Triton101]

System is locked to primary clock reference, that's all that DTC 103 means.

it could be the fiber daughter boards as you mentioned, but run the test, see if you get errors.

there are loopback test that can be run from ld 135, get the older Docs, they have the commands for 1000s. (5.5 docs has it for sure)

could be the cpu(call server) also...who knows...

just noticed that you did try the stat fil in ld 135, and it comes back uneq.... sorry

1000s will have the NTDK20XX card in a single chassis(NTDU30) for it self, and each expansion chassis will have one as well, and use either NTDK83 or NTDK99 ip daughter-boards...

if you have IP, just look at the back of the chassis and see if you have RJ45 patch cords going to the Ethernet plugs.... might be a matter of using new LAN ports on the LAN switch?, it could be a duplex mismatch (some change that might have been done).

there were:
cse1000/cs1000s
cs1000m cabinet
cs1000m chassis
