Hello ,


WE ARE USING "WINFIOL-MD110 SYSTEM"

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

please advise me to solve this issue.

Thanks
 
Every body have md110 work with winfiol
Check trm in route properties
 

thanks inlsp05 for reply,

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


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

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
 

Thank you for advise

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

 
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.
 

<ROCAC:TRM=6, ROU=1;
EXECUTED

<ROCAC:TRM=6, ROU=2;
EXECUTED
I have tested after change trm to 6 but still volume is low.

any idea?

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

himdp, do you mean this :

<LSCOP:LIM=1;
LIM SWITCH MULTIPLE POSITION DATA
EQU ATTN CONNECTION STATUS CONTROLLER ADDR
A B LIM UNIT PTR
1-0-20-00 1-1-10-25 2 TWO WAY MAIN-AUXILIARY 1 OLP1T H'0009
1-1-10-25 1-0-20-00 2 TWO WAY AUXILIARY-MAIN 1 OLP1T H'0009
END
 
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.
 
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.
 
activenew, what is RODAP for the route and what TLU are you using?
