X.25 Packet Switching Analog and Digital Leased Line Dial Migration ISDN Frame Relay

Operators are planning to move to next-generation networks (NGN) but need to continue to support legacy services such as X.25, leased line, ISDN, and Frame Relay. Virtual Access products solve this problem of legacy support by allowing for the transport of legacy services over next-generation networks with DSL and fibre access, making it possible for operators to sell legacy services while still moving to next generation architecture.

X.25 Packet Switching

Our X.25 solution allows you to achieve your NGN migration goals without affecting service or revenues. The solution successfully migrates all X.25 access methods, including X.31, dial (triple X), and leased line. It consists of three components:

• The Always-On Server provides a direct replacement for existing public X.25 packet switching nodes. The AOS supports both traditional X.25 access and IP access over an NGN infrastructure.
  
  
• The Service Managed Gateway emulates the existing line interface NTU and then encapsulates the X.25 traffic in XMP (X.25 Migration Protocol) for transmission to the AOS over IP, DSL, or fibre access.
  
  
• Activator is the Zero Touch™ management system that remotely registers, configures, and upgrades the SMG and AOS network appliances.
  

Analog and Digital Leased Line

Leased lines are being phased out by operators worldwide. Users of these networks include utilities, financial institutions, lottery, security companies and traffic organisations. Operators and equipment manufacturers plan to discontinue support for these networks to focus on IP, however many users find it difficult to upgrade or replace their equipment to support IP. Virtual Access NGN migration products solve this problem by allowing operators to turn off leased line networks without requiring the user to upgrade or replace their equipment.

Dial Migration

Operators of Financial transaction networks can move ATM, Point of Sale and credit card customers to broadband without the need to purchase a new IP terminal infrastructure. This lowers communications and maintenance costs with the benefits of broadband speed and bandwidth on a secure network prioritised for financial transactions.

ISDN

We support a range of devices that offer ISDN/TDM emulation over an IP network, which can be used to transport voice or data traffic. The single-port device is typically used for remote sites, and a multiport device is used for concentrating traffic in the core of the network.

ISDN and Leased Line Frame Relay

Our Frame Relay NGN solution allows you to migrate your ISDN or leased line Frame Relay services to broadband IP infrastructure without affecting your existing Frame Relay customers.

The solution requires a Service Managed Gateway (SMG) at the customer site and an Always-on Server (AOS) connected to the existing network. The SMG provides Ethernet and an interface that simulates the existing legacy network termination. The SMG receives traffic from the user terminal equipment and encapsulates the legacy packets in IP for transport over the IP/DSL network. The AOS terminates the IP traffic that is received from the SMG, removes the IP encapsulation, and forwards the legacy packets to the endpoint.
