v.92 and v.44: The New High-Speed Modem Protocols
Pennswoods.net is pleased to offer
the latest technological advances to its customers. Two new modem
protocol standards have come into production-level use: v.92 and v.44.
These protocols offer new features previous ones have not and the possibility
of even faster dial-up connections to the internet.
What does this upgrade mean to you?
v.92 is an extension and update to the current v.90 high-speed modem
protocol. It supports the same fast connection speeds, but with these
additional features:
- Modem on Hold allows you to put your
internet connection on hold while you take or make a telephone call.
- Quick Connect shortens the length
of time it takes your modem to negotiate its connection to your
ISP by about half.
- PCM Upstream allows "56K"-like uploads
as well. Using v.90, the maximum upload speed is 31.2Kbps; under
v.92 it is possible to upload at speeds up to 48Kbps. This is important
to users who upload a great deal, audio and video streaming, and
other applications that depend on transmitting data.
- v.44 compression allows you to get greater
effective transmission rates than without v.44 even though the electrical
connection remains the same. In tests comparing v.42bis - the current
compression protocol - and v.44 in normal web-browsing conditions,
v.44 out-performed v.42 by up to 20%. This extra compression allows
you to achieve greater data throughput even though your connection
speed remains the same.
Is your modem v.92/v.44
capable?
Possibly. v.92-capable modems have been on the market since 2000/2001,
so if you have a new modem it may already have support for v.92. Even
if your modem doesn't currently support v.92, several of the most
popular modem manufacturers already have v.92/v.44 equipped drivers
available for their modems. If you have an upgradable modem manufactured
by one of these companies, all you need to do is download and install
the driver update and you're ready to go.
What do you need for Modem-on-Hold?
Call waiting on your line, as provided by your local telephone company,
a v.92-capable modem, and a software modem-on-hold client installed
on your computer. You can probably expect this software to come packaged
with your modem's drivers.
How does Modem-on-Hold work?
Modem-on-Hold works much like the current call-waiting used in voice
conversations. If you receive a call while you're online, the modem-on-hold
client will prompt you to take or ignore the call. If you choose to
take the call, just pick up the telephone. If you want to make a call,
the modem-on-hold client will allow you to suspend your modem connection
in the same way. Your modem connection will hold for four minutes
while you're on the phone. If this time is exceeded your internet
connection will be lost. When you're finished with your conversation,
just hang up the telephone and your modem connection will resume.
