Description
CentreCOM AT-3012SL, AT-3016SL, and AT-3024 SL Multiport Repeaters
provide low-cost connection for up to 24 IEEE 802.3 10Base-T network
segments. The series includes three different models, featuring 12, 16 and 24
shielded RJ-45 port connections for 10Base-T networks.
In addition to the twisted pair interfaces, each unit includes a choice of two
network ports for interconnection to a network backbone:
❑
An IEEE 802.3 10Base5 Auxiliary Unit Interface (AUI) for attachment
to coaxial (thick) Ethernet or an external transceiver
❑
An IEEE 802.3 10Base2 BNC port for attachment to thin Ethernet
This interconnection makes it possible for the repeater to connect to different
media (thick or thinnet coaxial, fiber optic, and twisted pair), using an
external transceiver.
The AT-3012SL, AT-3016SL and AT-3024SL Multiport Repeaters use the
latest technologies, including a custom Application Specific Integrated Circuit
(ASIC), and Surface Mount Technology (SMT). Using these technologies help
enhance functionality, increase reliability, and improve price and
performance.
The repeaters conform to the IEEE 802.3 specifications. This conformity
allows for a maximum of four cascaded repeaters through one of the 10Base-T
ports. It also enables a maximum of 1024 individual segments for
configuration into a single network by the extended use of fan-outs (see
Chapter 7 for configuration diagrams).
