The sound level very low

The sound level very low

(OP)


Hello ,


WE ARE USING "WINFIOL-MD110 SYSTEM"

We are facing a problem when communicating or receiving international calls, the sound level is very low┘łalmost can not hear anything.

please advise me to solve this issue.

Thanks

trm=7 ,it seem is high

RE: The sound level very low

Call to your provider and ask them add gain on this rou.

RE: The sound level very low

Is it possible to increase the sound to maximum for a certain exts?

RE: The sound level very low

Hi,
TRM "7" means not high (or low), it is the Position in the attenuation matrix.
Check, if the extensions und trunks have the correct TRM.

example :
here are the positions for the application systen "standard"
This positions are from market to market different !!

TRM Line type
0 Analogue/digital extension line, PABX operator line, IP extension
1 Reserve
2 Reserve
3 Reserve
4 Analogue external line
5 Digital external line
6 2-wire tie line
7 4-wire tie line

From line type To line type (TRM)
trm 0 1 2 3 4 5 6 7
0 2 2 2 2 2 2 2 2
1 2 2 2 2 2 2 2 2
2 2 2 2 2 2 2 2 2
3 2 2 2 2 2 2 2 2
4 2 2 2 2 3 3 4 3
5 2 2 2 2 3 2 3 3
6 2 2 2 2 4 3 4 3
7 2 2 2 2 3 2 3 2
ATTENUATION VALUES (dB)
D 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
.. -6 -3 0 +3 +6 +9 +12 +15 +18 +21 +24 +27 +30 +33 +36 +39
--> the value "2" in the Matrix means "0" dB.

about your question "to increase the sound to maximum for a certain exts"
YES, in the attenuation Matrix there are one or more TRM Position "reserved"
It is possible to change the attenuations values
(but I don`t know anymore, if this was possible with command or with "SACOS")

best regards,
Norbert

RE: The sound level very low

Hi,
if you take a look to the addr 89 to 90, the attenuation value is "00" (-6 dB, e.g. Maximum)
this means, for incomming calls from public you already have the max. value.

regards,
Norbert

RE: The sound level very low

(OP)

Thank you for advise

Next , What the solution to improve the sound quality for incoming and outgoing calls?

RE: The sound level very low

oops,
I think I was wrong with "00" (-6 dB, e.g. Maximum), it is the Minimum.
Can you try to Change the TRM for the route to "6" and test it again.

RE: The sound level very low

(OP)

<ROCAC:TRM=6, ROU=2;

I have tested after change trm to 6 but still volume is low.

any idea?

Thanks

RE: The sound level very low

activenew, you could always confirm the attenuation value being used by setting up a connection and using LSCOP.

RE: The sound level very low

himdp, do you mean this :

RE: The sound level very low

(OP)


any advise please?

RE: The sound level very low

This indicates that you have no attenuation/gain in either direction. You could try boosting the receive direction with -3db of loss (3dB gain) using SACOS of the transmission matrix but this could lead to instability especially on local calls which I assume are OK because you only mention international calls.

RE: The sound level very low

(OP)
himdp,

also the volume is low when call any cell phone in my zone.

please be patient with me, because this fast time hear about this

In my situation i want to increase volume sound for both call internal(0) and international(00) , what should i do ?


Thank you in advance.

RE: The sound level very low

activenew, what is RODAP for the route and what TLU are you using?

we are using TLU83

Thanks

RE: The sound level very low

No problem with delayed reply as long as you do replysmile
I just wanted to check that you have the maximum gain in the hardware which you do. TLU83 is a programmable board and digit 7 of VARC is 2 which sets the board for long line i.e. maximum gain. No improvements to be made there.

As snor already said, you already have the maximum gain in the trasmission matrix in SCP. However you have given the LSCOP for an OPI call the level for which is controlled by MPP as I recall. Is it just operator calls which are low or is it extension calls too? If extension calls are low too, can you please do an LSCOP for that call case.

RE: The sound level very low

(OP)


oK, there is no problem between extensions.

The problem occurs when you make or receive a call from a cell phone(extensions and operator).

can you please do an LSCOP for that call case? CAN YOU PLEASE QUIDE ME ??


thanks

RE: The sound level very low

As inlsp05 stated, the problem is with the service provider, not MD. You cannot get the gain you want with TRM, sacos, lsati or whatever....

fcpli

RE: The sound level very low

"can you please do an LSCOP for that call case? CAN YOU PLEASE QUIDE ME ??"
What I meant was make a call from a cell phone to an extension so that the transmission level is poor, then do an LSCOP as you did before with the call set up so that we can see what the actual value of attenuation is.

RE: The sound level very low

Hi activenew,
sorry, I miscounted from your SACOP in SCP. You have 0dB in both directions at present, so you can improve the situation by adding gain as I mentioned earlier. The TRM value is 7 on the trunks, you can improve this by doing ROCAC:ROU=x,TRM=4;

For a 2wire analogue public trunk, this is the correct setting anyway as mentioned by snor earlier.

The change to TRM will not change established calls so you must make a new test call afterwards and check with LSCOP.
The values in your SACOP look suspiciously like it has already been adjusted in the past as it is not normal to see that many zeros in the matrix.

RE: The sound level very low

Hi activenew, you need to make a test call to the public trunk with the call case which has low level i.e. cellphone or international. With the call still connected do CTDEI:DIR=xxxx; and LSCOP:LIM=1;

Also note if the connection level is any better.

The sound level a little bit better than before.

RE: The sound level very low

So maybe you washed your ears? There is no change in the attn according to your printout. Note that if you raise the gain with 3dB, the difference is very small for a human ear. In practice, you can raise the gain with 9dB max in the MD, the rest is just a number. But as you wish, keep changing TRM, but the result is not going to satisfy you.
What about the level if you call back thru the trunk to yourself? (MD-SP-MD). Or make a loopback from TLU83 to an extension board an try this way. Is the board OK?

Thank you for advise ,

I will try to do your suggestion ,i will feedback the result.
