Isup Redundant Deployment Model - Dialogic Vision CX Video Administration Manual

Dialogic® Vision™ CX Video Gateway Administration Manual

ISUP redundant deployment model

For a redundant and fault-tolerant system, two CX Video Gateways can be deployed
to provide higher availability. The gateways share a single signaling point code and
provide node-level redundancy.
The following illustration shows an ISUP model with two CX Video Gateways to
support redundancy. The redundant pair of gateways with ISUP terminations
seamlessly provides signaling services for multiple gateways as in the scalable
deployment model.
