Connecting BCMs Connecting BCMs lewmar (TechnicalUser) (OP) 6 Feb 05 13:49 Hi,I have few offices with BCM intalled. Is it possible to connect them together using VPNs and LAN cards or do I have to use IP trunking and WAN cards? RE: Connecting BCMs redcomet (TechnicalUser) 7 Feb 05 02:18 BCMs can be connected over LAN or WAN, depending on the type of connection you have. The connection can also be established through a VPN tunnel. IP trunking is always required if IP is used.
