CHAPTER 1
Introduction
What's new on the A850 ?
The A850 is the successor of the well proven A840 Gateway and
offers the following new features:
•
USB device support : USB based devices are supported as
long as they conform to the USB standards for the storage or
communication device classes. The device types that can be
used are
•
USB to RS-232 adapters or
•
USB modems.
Note: A list of supported devices will be provided with the Firm-
ware release notes. Devices not listed may work, but Adcon
advises not to try as such attempts and possible damage
resulting from it would be at the user's sole and own risk.
•
Multiple modem support: The A850 support more than one
modem. For every modem, the user can configure
•
a V110 mode whitelist which tells the A850 for which
phone number the digital V110 mode is supported (V110
mode is supported by most GSM and ISDN networks,
but not by POTS (analog) phone networks),
•
whether the modem should answer incoming calls (and
after which number of rings).
Note: A list of supported modems will be provided with the firm-
ware release notes. Devices not listed may work, but Adcon
advises not to try as such attempts and possible damage
resulting from it would be at the user's sole and own risk.
•
Protocol support: The A850 supports encrypted network
protocols, namely
•
SSH as replacement for TELNET,
•
HTTPS as replacement for HTTP.
Note: The unencrypted protocols is still be supported, however it
is highly recommended not to use them when accessing the
A850 over public (insecure) networks (especially the inter-
net).
