1.3.7.1 Ethernet connect
8 Ethernet connections are present for BSC1 and BSC2:
BSC1 LAN1 and 2 and BSC 2 LAN1 and 2 for connection to other nodes, routers, log server,
Network Management etc..
BSC1 WAN1 and 2 and BSC2 WAN1 and 2 for connection to corporate network, SIP units,
Remote desktop, Switch board (PABX), API etc.
Figure 1-28: CB412 connection board
The connection from BSC1 and BSC2 is coming from the LAN and WAN connector on the
front of the BSC412 front plate and connected on the backside of the connection box and
spitted out to LAN1 / LAN2 and WAN1 / WAN2.
NB: When using 2 BSC412’s there is a connection between the BSC1 and BSC2 LAN and
WAN on the backplane connection, this will be switched off by an electronic switch device
when there is a cable in both BSC1 LAN1 and BSC2 LAN1 and the same goes for the WAN
connector. This is to avoid recirculation of the signals
