ISUP models

The Video Gateway is available with the ISUP audio models and ISUP video models listed below. Each of these models can be configured for scalability and redundant capability.

This topic describes the:

Basic ISUP audio model

In the basic ISUP audio model, the gateway:

Basic ISUP video model

In the basic ISUP video model, the gateway:

The basic ISUP video model requires a mobile video device that supports 3G-324M.

Basic BICC video model

In the basic BICC video model, the gateway:

The basic BICC video model requires a mobile video device that supports 3G-324M.

ISUP scalable deployment model

For scalability, multiple Video Gateways can be deployed where the ISUP termination on one gateway provides the signaling between the SS7 access network and each of the other gateways in the system.

In this model, the gateways are configured to share the single signaling point code terminated by the gateway with ISUP interface. This configuration allows for high density deployments for a single signaling point code.

The following illustration shows the ISUP scalable deployment model.

ISUP redundant deployment model

For a redundant and fault-tolerant system, two 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 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.
