BCM50e and BCM50a: BCM systems with integrated routers

BCM50 is available with an optional integrated ADSL or Ethernet router. These units suit the
needs of small businesses and small enterprise branch offices that require external data
networking, such as Internet access or VPN-based networking to other offices.
Two variations of the BCM50 have an integrated router, depending on the WAN interface you
require. The two variations are the BCM50e (Ethernet WAN) and BCM50a (ADSL WAN). Both
routers have these data features:
• secure Internet access
• multi-site VoIP trunking using secure VPN tunnels
• wide-area VoIP applications with remote user support
• remote IP management and support using VPN clients

Common features and capabilities

BCM50a and BCM50e share the same robust set of functionality focused on secure Internet access
and VoIP.
BCM50e and BCM50a have three additional ports of Ethernet LAN for a total of six LAN ports
for local premises use. All Ethernet ports are 10/100 Mbps autosensing and support autopolarity.
Therefore, no crossover cable is required to connect data hardware to the unit. An additional port is
provided for WAN access, either Ethernet or ADSL, depending on the model.
