14 Chapter 2 System Overview
BCM50e and BCM50a have three additional Ethernet LAN ports for a total of six LAN ports for
local premises use. All Ethernet ports are 10/100 Mb/s automatic sensing and support automatic
polarity. Therefore, you require no crossover cable to connect data hardware to the unit. An
additional port is provided for WAN access for, either Ethernet or ADSL.
The following features make BCM50a and BCM50e attractive for small sites that want to become
Internet-capable and multisite enterprises with many small sites. Until now, these sites could not
be part of the corporate WAN because of the high cost of traditional WAN connectivity and
managed service.
