Chapter 11: Port network and gateway connectivity

Asynchronous Transfer Mode

The Asynchronous Transfer Mode (ATM) switch is a replacement option for the CSS or the direct-connect switch. Several Avaya ATM switch types can provide Communication Manager port network connectivity. Non-Avaya ATM switches that comply with the ATM standards set by the European Union can also provide Communication Manager port network connectivity.

Port Network Connectivity

ATM Port Network Connectivity (ATM-PNC) provides an alternative to the Center Stage Switch

(CSS) configurations for connecting the Processor Port Network (PPN) to one or more

Expansion Port Networks (EPN). ATM-PNC replaces the CSS in a DEFINITY R8r and later network with an ATM switch or network. ATM-PNC is available with all three Communication

Manager reliability options - standard, high, and critical. In addition, it offers ATM-PNC duplication.

ATM-PNC integrates delivery of voice, video, and data via ATM over a converged large bandwidth network, providing reduced infrastructure cost and improved network manageability.

ATM-PNC uses standards-based open interfaces that can be provisioned with either new or existing systems running Communication Manager.

Port Network Connectivity over WAN

ATM-PNC over a public Wide Area Network (WAN) represents an environment where the customer uses a service provider's ATM network between privately-owned ATM switches. The customer does not control the ATM switches in the network, including traffic policing policies and product quality.

Using a public WAN, Permanent Virtual Paths (PVP) may be set up between customer-owned

ATM switches similar to the dedicated circuits in a private WAN. However, ATM cell processing occurs in a public WAN so the customer is dependent on ATM switches owned and managed by the service provider.

Switched Virtual Circuits (SVC) use the ATM protocol to transmit voice-like applications over

ATM networks. The advantage of the SVC solution is that Communication Manager can dynamically signal the ATM network to provide more bandwidth as needed to handle peaks in the call traffic. If the ATM network cannot handle the additional traffic, calls will be denied.
