The list is only valid for modems containing the latest V.90 firmware for
the modem manufacturer.
V.90 client modems using Lucent chipsets need an additional command in order
to connect to an access server in V.90 mode. The following paragraphs
describe how to use the additional command to connect the modems using these
chipsets to an access server.
V.90 client modems using Lucent chipsets connect in K56flex mode by default
on any access server. To connect a client modem with a Lucent chipset in
V.90 mode, enter the following command:
ats109=2
If the modem responds with ERROR, the modem you are using does not contain
the Lucent chipset.
Known problems in the current release are:
- TDKModem V.34 PCMCIA (Model #DF2814C, Code Rev. 4.0) fails to
connect with MICA on 20% of call attempts.
- The Newcom V.90 internal client modem speed shifts and retrains
constantly and eventually drops the call.
- V.90 calls from a Zoom 1 MB modem may connect in async mode, which
results in spurious characters being received.
