The two WAN interface ports provide access to channelized T1,
channelized E1, and ISDN PRI lines. The WAN Interface ports come with
8-pin, RJ-48C jacks for attaching T1, E1 or ISDN cable connectors.
The Model 8000 RAC provides autosensed AUI (Attachment Unit
Interface) and 10BASE-T Ethernet ports to connect the unit to the LAN.
The AUI port allows connection of either 10BASE5 (thick Ethernet) or
10BASE2 (thin Ethernet), if you supply the appropriate transceiver. The
AUI port accommodates most standard tranceivers, also known as Media
Access Units (MAUs).
The Link LED is an Ethernet link layer integrity indicator. The LED is
on when an active 10BASE-T segment is attached, and off when an AUI
segment is attached.
The Sync port is used for trafficking data over several physical interface
types such as X.21, V.35, RS-422, and synchronous RS-232.
The Model 8000 RAC has a 9600-baud console port with an 8-pin,
modular jack for attaching the console. The console port provides access
to the ROM monitor commands when the Model 8000 is in Setup mode
and provides access to the console commands when the unit is running.
