bc11 niu buffer full & hang problem

bc11 niu buffer full & hang problem


I had a BC11 system with NIU for connecting to external voice mail.
Right nwow, whenever VM send me a series of instructions to turn on the message light( MAX 200 BYTE).The NIU will just hang.
May i know,why the default XON/XOFF handshake is not ' ON ' only on BC11 system.

I do not has any problem if i used
1. NIU with BC10 &
2. ICU card.

Any info to solve this issue is welcome.

RE: bc11 niu buffer full & hang problem

because HARDWARE handshaking(RTS/CTS) is more performant (only port 1 of the NIU) than software handshaking. if you MUST use software handshaking(XON/XOFF) make sure that both sides support it. if you still have icu card, I would put the link on the ICU, it's more stable anyway...

RE: bc11 niu buffer full & hang problem

Hi tigerlow66

I agree in what whosrdaddy says!
Save and use ICU boards for all V24/RS232 applications to obtain the most stable systems for external voice mail or intercept.
NIU/NIU2 boards are to be used for LAN application.

Best regards from the doktor.

RE: bc11 niu buffer full & hang problem

The Xon/Xoff is turned on by default on the port 2&3 and is the only way to make flow control. There is a problem for this in the NIU firmware but that is fixed from R13 and uppwards (current version is R16). If you use this firmware it should be no problem.

Good luck

RE: bc11 niu buffer full & hang problem

Current "official" NIF fw is R14A
Released with BC11Sp13 and BC12Sp1 .

RE: bc11 niu buffer full & hang problem

The current official NIF for NIU is R15A and the latest NIF for NIU2is R4A.
Belive me, I know.


RE: bc11 niu buffer full & hang problem

anyway, don't use r4a & r15a for sms application, this is solved in r5a (niu2) and r16a (niu) and these are official releases

RE: bc11 niu buffer full & hang problem

I have just been at the Servicapack area
And there is no reference to other .

So anyone ..
Please inform me where to get the at the servie support plaza . But NIU1 only R14A is posted. NIU2 R2A .

I have NIU2 R4A (but got this from Ericsson by email .
No newer NIU1 file than R14A though .
(There is no firmware in the Sp1 zip file either
 only ELF32R2B1.FW )

Believe me i don't fare with lies.

Heres BC12 SP1 ( NIU1 file download is R14A)

3.1      General implementation instruction
3.1.1      General implementation instruction
The CNA files are used for automatic update by the SAM toolbox ESD (Ericsson Software Distributor) application (For more information see ESD manual). The following steps should be done:

Copy all .cfg files, which are placed in subdirectories .. bc12xx.SP01 esd helpfile.*, to the Distribution files (.CFG, .INI) path defined in Options Settings.

Set up the job in the ESD by choosing menu item Job list>New>Job list file and follow the Job Wizard.

ESD tool can be used if the customer's PABX is entered into the customer database which is administrated by Customer Database Administrator.

Select file bc12sp00tosp01xx.cfg for updating from BC12 to SP1. (xx stands for Application system version e.g. st for standard system).

Select Continue without firmware switching. Firmware switching shall be done after system update.

After Job Wizard is finished, choose menu item Update > Start. ESD will now update the system automatically.

FR 100269 in EAP1 swaps the meaning of bit D24 and D25 in the ADC parameter to make it consistant with BC11.
After have performed the update with ESD it is therefor necessary to do RODDE on the DEST codes that have D24-D25 set to 01 or 10.
Swap them and do RODDI again.

Note! For DEST codes that have D24-D25 = 00 or 11, you do not have to do anything.

Make a system dump.

Check the result of the system update with MD Inventory Tool. Reference .mcc is placed in subdirectories .. bc12xx.SP1 mcc. (For more information see MD Inventory Tool Manual)

For D4 firmware update you need to manually copy the firmware to the HDU filesystem. To perform the update follow the instructions for CNTLI;

If IP-extensions are used in the system, it is necessary to restart IPLP to reset the counters for number of registered IP-extensions per ELU32 board. This measure cause traffic disturbance and should be done during low traffic hours. To find out in which Lims IPLP is loaded, use command CNPIP:UNIT=IPLP;. Unregister all IP-extensions by command IPURI:DIR=ALL,FORCE=YES; and then immediately restart IPLP in all Lims by RFPUI:UNIT=IPLP, Lim=X;

RE: bc11 niu buffer full & hang problem

Hello whosrdaddy,
I have just talked to the firmware designer,
he is very suprised to know that r5a and r16a is official releases.
Have a nice day.


RE: bc11 niu buffer full & hang problem

Btw just checked BC11 sp13
There is NIU1 R15A ( no R16A )
NIU2 R4A ( no R5A )

I guess i better send an email to my E/// contacts.

RE: bc11 niu buffer full & hang problem

firmwares R5A & R16A were released after a metrix report issued by us after we discovered that sms communication port gets closed in high traffic cases. so MDsup is right in saying these are not "official" releases since they're not released with a service pack, but they will be released by E/// (on the knowledge base i presume). All I'l saying is not to use R4A/R15A if you have sms application on it.

I hope this clears up this matter.

RE: bc11 niu buffer full & hang problem

Okay the NIF issue is outdebated and clear.
I'm curios why BC12Sp1 has been released with older
fw than BC11Sp13 though .
There wasn't that great timeperiod between the releases.

RE: bc11 niu buffer full & hang problem

because the firmware wasn't there yet I presume, this is the list for SP13 :

RE: bc11 niu buffer full & hang problem

Sorru guys,

I had updated my NIU to P16C via Ericsson Service Plaza.Unfortunately, The NIU still hang after VM send in less than 200Bytes of message waiting info. to MD.Right now, even i RFBOI the NIU is still dead.It always get error as follow :
DATE     TIME      ALP  NOIF  EQU          BRDID
07DEC03  00:41:43  1    3     001-0-60-02  106  

Initially i am using port 1 , but hang .therefore i had move the VM to port 2 now,but still hang.

Is there any work around method, so that i can has an interim solution for the customer.

My MD VERSION=LZY2035175/5/BC10CNA137/R3A

NIU is P16C now.

So far from moving port 1 to 2 , it only last less than 4 hrs,it when dead again.

Thank You

RE: bc11 niu buffer full & hang problem

It then do not seem like a Xon/Xoff problem. Do you know for sure that the VM system supports Xon/Xoff. Do also check for fault signals when the system hang. Also use some kind of v24 sniffer software and look at the comunication in between. Be sure that the cable lenght is no more than 15 meter.

RE: bc11 niu buffer full & hang problem

Hi Fidde,

Definitely within even 10 feet.

Yes, VM support Xon/Xoff.

Thank you

RE: bc11 niu buffer full & hang problem

Perhaps lowering the baudrate to 4800 or 2400
would help.

RE: bc11 niu buffer full & hang problem

Hi SYAR2003,



RE: bc11 niu buffer full & hang problem

VM support xon/xoff you say , but is it programmed
to use it .

Also concider a fake null/not Null modem/cable interface between .
Something that loops RTS/CTS and DTR/DCD/DSR in both directions so that just the TxD,RxD,GND is the really needed circuits in both ends.
