Patton electronics 2784 NAU Specification Sheet

Contents

The 2784 NAU provides integrated voice support bypresenting 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 bycustomizing the DS0 channel selection configuration throughthe SNMP/HTTP NMS (see screen snapshot, opposite).DS0s can also be identified as dial-in modem ports. With thisfacility, 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 maximizefacilities by answering remote access calls within the 2784,while switching calls to the PABX to handle corporatevoice–all at the same time. Now users can call the corporatevoice and data networks, using different telephone numberson the same T1.The 2784 NAU offers a flexible and cost-effective networkaccess solution using Frame Relay over a multi-serviceT1/E1 connection. Designed to be simple and efficient,Frame Relay is a data networking technology for connectingremote offices over the Wide Area. While eliminating theneed for individual and expensive leased lines, Frame Relayprovides distance insensitive connections to remotenetworks. 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 physicalcircuit, which allows the 2784 to forward data over thoseconnections to its intended destinations. Using RFC-1490multiprotocol encapsulation and the 2784's sub-interfacearchitecture, each virtual circuit is multiplexed over a singlephysical interface. The 2784 NAU scales to supportadditional connections without adding to capital equipmentcosts.By combining the capabilities of a CSU/DSU, FRAD androuter, the 2784 provides scalability without the additionalcosts of multiple pieces of equipment.APPLICATIONSPatton 2784 NAU ApplicationsFrame RelayCorporate Voice Integration
