Patton 2784 NAU Applications

Frame Relay

The 2784 NAU offers a flexible and cost-effective network access solution using Frame Relay over a multi-service T1/E1 connection. Designed to be simple and efficient, Frame Relay is a data networking technology for connecting remote offices over the Wide Area. While eliminating the need for individual and expensive leased lines, Frame Relay provides distance insensitive connections to remote networks. Connectivity is established through logical end-to-

end connections [Permanent Virtual Circuits (PVCs)] between the 2784 and the remote office.

Frame Relay provides multiple PVCs over a single physical circuit, which allows the 2784 to forward data over those connections to its intended destinations. Using RFC-1490 multiprotocol encapsulation and the 2784's sub-interface architecture, each virtual circuit is multiplexed over a single physical interface. The 2784 NAU scales to support additional connections without adding to capital equipment costs.

By combining the capabilities of a CSU/DSU, FRAD and router, the 2784 provides scalability without the additional costs of multiple pieces of equipment.

Corporate Voice Integration

The 2784 NAU provides integrated voice support by presenting up to 24 voice/fax calls onto the T1 DSX-1 Drop- and-Insert port. The user may select the number of channels (1-24 voice/fax calls) to be "dropped" onto the PABX port by customizing the DS0 channel selection configuration through the SNMP/HTTP NMS (see screen snapshot, opposite).

DS0s can also be identified as dial-in modem ports. With this facility, the 2784 will intercept and answer V.90, K56Flex™ , V.34+ and ISDN BRI users via built-in DSP modems.

This allows the 2784 to minimize costs and maximize facilities by answering remote access calls within the 2784, while switching calls to the PABX to handle corporate voice–all at the same time. Now users can call the corporate voice and data networks, using different telephone numbers on the same T1.
