The 1100DAB Digital Audio Bridge is an expansion unit that is used in the GLOBALCOM® system to provide a way to bridge CobraNet® audio across local networks or VLANs. It is used to send and receive audio to GLOBALCOM® systems or Legacy ACS® systems that reside on multiple networks. Each network connection is dual redundant, allowing the maximum possible reliability in network connectivity. The 1100DAB can coexist with data traffic over existing Ethernet networks saving money and by eliminating additional infrastructure costs. The support of the 1100DAB allows up to 8 channels of CobraNet® being bridged between two networks in each direction (8x8).
The device is added to the system and configured through the GLOBALCOM® System Management Center on the 1100/1200ACS that manages the 1100DAB. By using a network-based bridge, announcement management will be linked and routed resulting in announcement distribution.
