Subject: Re: [USR-TC] V92 enabled/disabled by AT string dynamically?

ATS$ on DSP's console(chdev mdm x, x=1..n) shows this:

S77 Bit Mapped V.92 Contol
     1 = V.92 Feature Disable
     2 = V.92 PCM Upstream Disable
     4 = V.92 Quick Connect P1 Disable
     8 = V.92 Quick Connect P2 Disable

Try to set S77=15. It will disable all V.92 activity. 15 = (8+4+2+1)

S78 V.92 Modem On Hold Timeout
Setting S78=0 will disable v.92 moh.

Maybe this can help you.

We currently utilize DNIS to service users with 2 numbers. Both numbers roll to the same trunk group and are setup via DNIS AT commands.

A v.90/v.92 and a v.34 line. The V.34 number is used when due to firmware or other factors it's better for them to get a stable V.34 connect than trial with the v.90 handshakes. 

 

We do this by setting our V.90 number with AT&N0, and our V.34 with AT&N14&U1.

Since V.92 has been turned on, these floor/ceiling values no longer work, and a v.92 53.3 connection is successfully connected on the V.34 line.

These ceiling values weren't intended to work with V.92. It notes in the documentation that it only refers to x2/v90.

 

So in order to bypass this little issue, I want to disable V.92 (on V.34 number) and therefore reenable the Ceiling values.

According to TCM, S77.0 Register controls V.92 Master setting. 

On (1)   Default

Disabled (2)

 

Unfortunately ATs77.0=2 causes the modem not to answer. Tacking on autoanswer s0=0 or s0=1 doesn't help.

 

Does anybody know an AT command to disable V.92 on HiperDSPs?

The S-registers apparently don't work, is there a +PIG or & type command to do this?
