Cisco FXO and Hughes DIRECWAY FXS Disconnect Problem

Hi All!

I have Cisco 2811 with VIC2-2FXO card and Hughes DIRECWAY voice gateway (FXS ports).

When DIRECWAY disconnect call, Cisco FXO port stays active.

I tried configure custom cptones and supervisory disconnect, but where is no result.

Cisco 2811 config

voice class custom-cptone Hughes

dualtone busy

frequency 450 1350

cadence 350 350

dualtone disconnect

frequency 450 1350

cadence 350 350

voice-port 0/2/0

supervisory disconnect dualtone mid-call

supervisory custom-cptone Hughes

pre-dial-delay 2

no battery-reversal

input gain 5

output attenuation -6

no comfort-noise

cptone CN

timeouts call-disconnect 3

timeouts wait-release 3

connection plar opx 2073

!

where is my mistake?

IOS version

Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version 12.4(17), RELEASE SOFTWARE (fc1)

Disconnect signal is attached.

Thanks!

Hi,

your frequency configuration appears correct, however the 1350 Hz is about 10 dB louder than the 450 one. There are also weaker components at 2250 Hz and then outside the telephone range, see attached file.

Try configuring "freq-power-twist" under voice-class to like 12. The default of 6 dB appear insufficient for your tones.

Thanks for help!

I tried to configure freq-power-twist to 10 and 12 values, but there is no result :(

freq-power-twist 12

How to know about signal level? may be it's too low?

Is there a bug of IOS of DSP processors software?

Hi,

If you could could upgrade to 12.4(11)XJ4, that might help, altogh I doubt so.

The signal you recorded appears strong. I'm not sure if the presence of other frequencies hinders the DSP in recognizing the tones.

On the other hand, I think the problem is just in getting the tones right. Are these tones the same as some country or telco in the world ? Have you verified that the device doesn't actually do a power denial a battery reversal ?

Re: Cisco FXO and Hughes DIRECWAY FXS Disconnect Problem

Also, can you try configureing all the parameters under a single voice class and reference it in the disconnect command, like for example:

voice-port 3/1/1

supervisory disconnect dualtone pre-connect voice-class 90

voice class dualtone 90

freq-pair 1 350 440

freq-pair 2 480 850

freq-pair 3 1000 1250

freq-max-deviation 10

freq-max-power 6

freq-min-power 25

freq-power-twist 15

freq-max-delay 16

cadence-min-on-time 50

cadence-max-off-time 500

cadence-list 1 100 100 300 300 100 200 200 200

cadence-list 2 100 200 100 400 100 200 300 300

cadence-variation 8

Re: Cisco FXO and Hughes DIRECWAY FXS Disconnect Problem

thanks for answer!

I have not command voice class dualtone in my IOS.

(config)#voice class ?

aaa AAA Parameters

busyout Set global voiceport busyout monitoring

cause-code Cause code list parameters

codec Set codec global parameters

custom-cptone configuration of customized Call Progress Tones

dualtone-detect-params dualtone detection parameters

h323 H323 Parameters

media Media settings for voip calls

permanent Permanent connection (call)

uri Voice URI class configuration commands

I have wrote to my satellite service provider to change gateway disconnect type. In answer i have screen shot (only 450 Hz for disconnect!!!). I think, there is tone disconnect method only..
