2. About Cisco Unity Bridge • Gateway between Cisco Unity and Octel node on Octel analog network • Bridge communicates with • Octel node using Octel analog protocol • Cisco Unity using digital networking • A separate license from the Cisco Unity license • In multiple Cisco Unity installations, only one server needs to be configured for Cisco Unity Bridge (bridgehead). • Message traffic may dictate multiple Cisco Unity Bridge servers for load balancing. • Cisco Unity Bridge is installed on a dedicated hardware platform.

17. Summary • Cisco Unity Bridge is used to send messages between the Avaya Octel system and Cisco Unity. • Octel networking is the networking between Octel nodes over a proprietary protocol. • Cisco Unity bridge networking is the ability to use Cisco Unity Bridge to send messages between the Cisco Unity and Avaya networks. • Cisco Unity bridge networking with a remote Cisco Unity Bridge means that Cisco Unity Bridge can be located across the WAN so that it can be collocated with the Avaya system. • Multi-node Octel networking is defined as multiple Octel nodes networked together. • Cisco Unity Bridge in Multinode Octel networking allows the Bridge to act like part of the Octel network so that it is treated like a peer.

18. Summary (Cont.) • “Collapsing a node” means removing an Octel node and replacing it with a Cisco Unity node that will use Cisco Unity Bridge to communicate with the remaining Octel network. • Avaya Interchange can take on the function of a protocol translator, taking in VPIM and AMIS, then translating the information to the Octel networking format. • Cisco Unity Bridge can be a part of multinode Octel networking with Interchange. • When collapsing a node with Interchange, Cisco Unity Bridge will look like an Octel node, and the collapsed node will use Cisco Unity Bridge to get to the Octel network. • Using Avaya Interchange and other Avaya products, it is possible to create a digital Octel network (Octel to Octel).
