2.4.8BPM-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

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.

2.4.9BPM-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

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.
