Physical Connectivitybbbbbbbb
The system assembly that provides the DEFINITY LAN Gateway brouter
application is a pair of circuit packs (a Multi-Function Board [TN2208] and an
Ethernet Alarm Board [TN2170]), and a spacer, that provide a processor, hard
disk, tape unit, Ethernet, and serial ports.  See Figure 13-1.

However, if the system assembly is installed in a DEFINITY G3V3 or earlier, or in
a DEFINITY G1, the circuit pack is recognized as a BRI circuit pack, and the
display circuit-packs cabinet command shows only one of the physical slots as
a TN556 (BRI) circuit pack.  This is an unsupported switch configuration, and
these switches should be upgraded to G3V4 or to a maintenance release of
G3V3.

The terminal block, in turn, should be attached using suitable 10BaseT class 3 or
better wiring to an Ethernet hub or an Ethernet hub adapter in the host to which
physical connectivity is desired.
NOTE:
AT&T strongly recommends (both for security and performance reasons)
that the Ethernet connectivity between the MFB and the set of hosts with
which it will communicate be a separate LAN segment. Customers who...

To pass messages, the brouter references the table of virtual BRI ports, client
host names, and link numbers. A maximum of 8 such connections or mappings
can exist simultaneously (only 4 are useful in a DEFINITY G3s).  Each entry in
the table has the following form:
