3174/3274 I-MUX
8
Configuration 2:
This configuration consists of the MX330A-C
and an IBM 3299/32 thirty-two port terminal
multiplexor connected by a coaxial or twisted-pair
cable (Type 1, 2, 6, or 9).
NOTE
This configuration does not support
fiberoptic connection.
The MX330A-C accepts up to four 3174 or 3274
coaxial lines and combines them into a single
multiplexed output on coax or twisted-pair cable.
This output is received by the IBM 3299/32, which
provides 1-to-32 demultiplexing. Each port is
connected to a device.
This configuration allows a maximum total distance
between controller and device of about 2.8 miles
(4.5 km)—see Figure 2-4.
NOTE
Maximum distance is subject to
controller timeout. For maximum
distance calculations, refer Section
2.4.2.
