Modems Supporting V.90
The following V.90 modems have been tested and can successfully establish
V.90 connections with this release of Cisco MICA Portware, version 2.6.1.0:
- 3Com Megahertz Ethernet +56K PCMCIA
- 3Com Megahertz V.90 Cellular PC Card
- AOpen
- Boca
- Diamond Supra
- Garnett
- Hayes Accura V.90 (Rockwell chipset)
- Hayes Accura V.90 (Lucent chipset)
- Hayes Optima V.90 (Lucent chipset)
- MagicExpress MX56V (T1 only)
- Motorola Modem Surfer
- Motorola Voice Surfer
- Multitech 5634ZBA (Lucent)
- Multitech 56000ZDX (Rockwell)
- Psion V.90 PCMCIA
- USR Courier V.Everything
- USR Sportster
- Viking FM56K V.90 PCMCIA
- Zoom
Note Portware version 2.6.1.0 enables V.90 56K connections while continuing
to support K56flex 1.1 connections. The client modem determines which
modem protocol is to be used in a connection. Note that X2 is not supported
in this release and because V.90 generally provides better performance
than either K56flex or X2, X2 will not be supported in the future.
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. You may also check your modem for Lucent chipsets
with this command:
ati11
A modem using a Lucent chipset will respond with output similar to the
following:
Iati11
