2.4.8 BPM-BNC
The Magnum BPM-BNC
bridge module is equipped with a
standard 10BASE2 coax connector.
This BPM is self-learning and filters
and forwards packets at full Ethernet
wire speed. This module is used for
10BASE2 ThinNet (commonly
referred to as BNC) connections and is Magnum BPM-BNC
designed to isolate the local segment (i.e., the users and devices connected to the
Magnum unit housing the BPM) from the connecting network (i.e., the users and
devices connected through the BPM’s media connector).
The BPM-BNC module is designed with a special switch -selectable internal
termination function that eliminates the need for a "tee" connector and a 50 ohm
terminator. For switch details, refer to RPM-BNC, section 2.4.1. The BPM-BNC
module includes an FWD-I LED and an FWD-X LED, which are visible from the
exterior. The FWD-I LED blinks GREEN to indicate that packets are being forwarded
INTO the local Magnum hub. The FWD-X LED blinks GREEN to indicate that packets
are being forwarded OUT of the local Magnum hub.
2.4.9 BPM-AUI
This local-bridge module is
equipped with a 15 pin female AUI
connector and a slide-lock. It is self-
learning and filters and forwards
packets at full Ethernet wire speed. It
is used to provide segment isolation
from a 10BASE5 (ThickNet) backbone or any Magnum BPM-AUI
AUI segment. A transceiver is required when connecting to a ThickNet segment and
the BPM-AUI supports this convention.
The BPM-AUI is equipped with one FWD-I LED and one FWD-I LED, which
are identical to those of the BPM-BNC (see Section 2.4.9). The BPM-AUI connector
supports standard IEEE signals, which are summarized in Table 3.3.2 of Section 3.3.2.
