ADSL Modem
TeleBoss units that are ADSL-modem-equipped can connect to the Internet via ADSL. This means that the unit can
reach Internet hosts and have an Internet IP address but the address is completely firewalled so you will not be able
to, for example, ping the unit's DSL interface IP address.
Note:
Full ADSL modem functionality is only available on TeleBoss products with the “SitePath” build (version
2.03.000 or greater). If there is any question about whether your unit has the SitePath build, contact
Installation
If installing the ADSL modem for the first time (not factory installed), follow these installation instructions:
Make sure the the host T850 is powered down and remove the telephone line from the internal modem (if
used).
Remove the two screws from any of the expansion bay covers on the back panel of the T850 and set the
cover aside. Carefully slide the ADSL modem card into the plastic rails inside the expansion bay and
push the card in all the way. Replace the two screws previously removed to hold the card securely in the
bay.
Power up the host unit.
Description of ADSL
ADSL (Asymmetric Digital Subscriber Line) is a technology where data is modulated onto higher frequencies of
copper telephone lines not used for voice in such a way that upstream and downstream data rates differ. Certain
Asentria TeleBoss units can have an ADSL modem expansion card installed to provide an interface to a line. The
machine on the other end of the line is a DSLAM (Digital Subscriber Line Access Multiplexer). DSLAMs exist typically
inside telephone company central offices (COs) but also exist in standalone hutches (remote DSLAMs).
The abbreviations "DSL" and "ADSL" are used interchangably in this documentation; where "DSL" is written, "ADSL"
also applies unless the difference is explicitly specified.
Certain terms and acronyms are used throughout this guide that may require further explanation. These are hyper-
linked to the
Configuration
The ADSL modem can be configured via two methods in the TeleBoss unit:
For simplicity, only the Setting Keys method is discussed in this guide. However, as you are working through the
configurations you are welcome to also use the related Command Line menus (Setup ->Network Settings -> DSL
Settings) or web-interface menus in your TeleBoss unit to view or configure specific settings.
There are four ways to configure ADSL depending on the specifications from your ADSL and ISP providers. In some
cases the ADSL provider and ISP provider are the same. For simplicity and unless otherwise specified, "ADSL
provider" means the entity that provides all settings required for the unit to use the Internet over the ADSL.
The key datum to get from your ADSL provider is what type of addressing is to be used:
PPPoA
over
),
PPPoE
Static
, or
. Make note of this, then proceed with configuring the ADSL modem as
described below.
Set the value of the
net.dsl.type
Setting Key to either
PPPoA
,
PPPoE
,
Static
, or
DHCP
as instructed by your
ADSL provider. This is the most important DSL setting since its value determines what other DSL settings are
applicable to the DSL configuration. Each of these connection protocols requires specific settings, so refer to the
paragraph below for the protocol you will be using. But first, there are some settings that must be configured
regardless of how
net.dsl.type
is set.
