Highlights
Internet
Service Providers. MultiAccess offers a rock-solid
solution for ISPs. Configure the various line interfaces to suit
your environment, plug in your channelized T1 and/or T1/E1 PRI ISDN
line and begin servicing your client base. The powerful hardware
provides the ability to serve all calls with high performance and
maximum throughput.
Dial-In/Dial-out
Simplicity.
MultiAccess makes it easy to provide remote access to your LAN for
V.92/56K and BRI ISDN remote users. With the potential to support
96/120 concurrent sessions, this solution can easily support all
of your dial-in telecommuters and road warriors. In addition, LAN
users can share the MultiAccess ports for dial-out data connections.
Flexibility
to Grow. MultiAccess can support up to four digital
trunks (T1/RBS and/or T1/E1 PRI ISDN) and provide up to 96/120 ports
per rack unit. This allows you to buy what you need today and populate
with additional modems as your server needs grow.
Versatile
Integration. MultiAccess supports channelized T1
and/or T1/E1 PRI ISDN services. All necessary software comes preinstalled
and ready to be set up for your configuration.
WAN
Communications. MultiAccess ships turnkey for channelized
T1 or T1/E1 PRI ISDN and populated with 24 or 30 universal ports
for V.92/56K and BRI ISDN dial-up connections. The high density
modems provide V.92/56K dial-up speeds. In addition, they are manageable
from remote locations using platform-independent, industry standard
protocols.
Quick
Connect.
The quick connect feature reduces the dial-up connection time by
as much as 50% for a modem to handshake to an ISP or other connection.
Modem-on-Hold.
The modem-on-hold feature works in conjunction with call waiting
provided by the phone company. Users can answer a new phone call
for up to 16 minutes without dropping the modem connection. Users
are then able to resume surfing the Internet after they terminate
the voice call.
V.44
Compression.
V.44 is a new data compression standard that can improve the current
V.42bis data compression anywhere from 20 to 60%, up to as much
as 200% for certain types of highly compressible data. This compression
technique enables data throughput rates of higher than 300K bps
- much faster than today's’stypical rates of 150 - 200K bps. For
users, this means that your Web browsing will be much faster.
Management.
MultiAccess includes robust management support allowing a network
administrator to securely manage the devices either through a web
browser or at the command line. The browser-based option uses the
HTTPS protocol, also known as SSL (Secure Sockets Layer) to provide
128-bit encryption to secure the management session. The command
line interface is accessible via SSH (Secure Shell) and supports
SCP (Secure Copy) and SFTP (Secure File Transfer Protocol) to help
provide maintenance support.
SNTP
Support.
MultiAccess also has a built-in Simple Network Time Protocol (SNTP)
client which enables it to synchronize its clocking with a remote
time/clock server on the Internet. This feature is useful for accounting
purposes.
