Well, I posted that I had seen it, and I did not typo. I have a Hayes
Accura 56k external speakerphone modem. It has 1.12 firmware in it. It
tends to retrain a lot (partially because my apartment has cruddy
lines). If I just let it connect with the init string from the .INF
file, it will connect at 50K most of the time, but retrain constantly
during telnet connections. If I FTP a big file down, it will usually
not retrain while the file is moving. It seems to train down when I
type and try to train back up when it is idle.
Anyway, to try to limit the retrains, I put a '+ms=,,,42000,,,' on the
init string, which limits the PCM connects to 42K, and that is what it
usually connects at. However, I have had it connect at 42K and train
down to as low as 4800. I am checking speeds via SNMP on the PM3. I am
pretty sure it really is 4800, as things go _really_ slow when this
happens.
I just went looking in my RADIUS records, and here is an example:
Mon Jan 19 15:41:39 1998
Acct-Session-Id = "0C003D57"
User-Name = "someuser"
NAS-IP-Address = someip
NAS-Port = 14
NAS-Port-Type = Async
Acct-Status-Type = Start
Acct-Authentic = RADIUS
Connect-Info = "44000 LAPM/V42BIS"
Service-Type = Framed-User
Framed-Protocol = PPP
Framed-IP-Address = someotherip
Acct-Delay-Time = 0
Timestamp = 885246099
Mon Jan 19 15:48:23 1998
Acct-Session-Id = "0C003D57"
User-Name = "someuser"
NAS-IP-Address = someip
NAS-Port = 14
NAS-Port-Type = Async
Acct-Status-Type = Stop
Acct-Session-Time = 402
Acct-Authentic = RADIUS
Connect-Info = "4800 LAPM/V42BIS"
Acct-Input-Octets = 5434
Acct-Output-Octets = 3024
Acct-Terminate-Cause = Lost-Carrier
Service-Type = Framed-User
Framed-Protocol = PPP
Framed-IP-Address = someotherip
Acct-Delay-Time = 0
Timestamp = 885246503
There are quite a few examples of this in the RADIUS logs, and since I
have had it happen to me several times, I don't think it is a cosmetic
or reporting bug.
Maybe it isn't _supposed_ to be possible, but it does look like it is
happening.
