System Overview
BRI version
BCM50 integrates 2-port BRI S/T trunks for EMEA and Asia Pacific (APAC) markets to give this
option to customers who need digital trunking. The analog trunk versions will still be available
separately for those customers who require them.
R2MFC MBM support
BCM50 supports the R2MFC MBM in selected Caribbean and Latin America (CALA) and APAC
countries. See the country matrix in “The I24 KEM is ideal for Secretary and Health care. Global
markets” on page 29.
EU compliant routers M222/252 firmware
BCM50 routers deliver Removal of Hazardous Substances (RoHS) compliancy for network
infrastructure, or 5/6 compliancy. This requires new hardware for both the Ethernet router and the
ADSL router. The new hardware is based on a common architecture for both routers and is also
common to Contivity EU releases.
These new features apply to the M222/252 routers only. A software upgrade will be available for
installed M221/251. The following features align to Contivity 2.5 with the addition of VPN client
termination support.
• VPN Client Termination (new)
• Port Restricted Cone NAT
• SIP firewall ALG
• Nailed Up tunnels
• SSH, SSL and Secure FTP
• New hardware support for ADSL2+
• Client emulation enhancements
• Client management privileges
• Failover IP assignment for automatic assignment of fail over site IP address
• X.509 digital certificates
• New DSL version support for ADSL2+
WAN failover
The new router hardware simplifies WAN failover as well as future management integration
through the internal serial connector. The new router also allows support for WAN failover on all
BCM50 platforms with M222/252 routers.
Note: M221/251 refers to the routers shipped with BCM50 1.0 units,
and M222/252 refers to the new EU-compliant routers shipping on EU
BCM50 1.0 and BCM50 2.0 units.
