Expansion Card The 833IS is an expandable unit and therefore provides for the insertion of an
optional expansion card in slot 2. The following expansion cards are currently
supported:
These cards allow the user to double the number of ISDN ports as well as doubling
the number of modems available in the system. If the unit was purchased with an
expansion card, it will come already installed in the unit.
Interfaces
LAN Interface The LAN interface is available for an Ethernet or Token Ring attachment to the
LAN.
Ethernet The Ethernet interface supports a 10 Mbps or 100 Mbps connection, through the RJ-
45 (supports 10Base-T and 100Base-TX) interface type. There is also a Link LED
associated with the interface which flashes when the interface is connected to the
LAN and data is being received.
Token Ring The Token Ring interface supports a 4 Mhz or 16 Mhz connection. It contains two
physical interfaces. A DB9 connector provides the STP interface used to connect to
a Media Access Unit (MAU) which utilizes the IBM style universal connectors. An
RJ-45 connector provides the UTP interface used to connect to a MAU using
Unsheilded Twisted Pair wiring. A LAN LED is provided to indicate successful
connection to the Ring and to identify activity on the interface.
ISDN interface There are two types of ISDN interfaces supported. A “U” interface (most common
in North America) and an “S/T” interface (most common outside of North America).
The type of interface you purchased should match the type of connection provided
by your Telephone network provider.
