A System and method for reducing and surviving failures in a voice trunking over ATM (VTOA) environment includes a CS-IWF complex having a plurality of interconnected CS-IWF units, each unit having a plurality of processors. An end office building may also be provided for interaction with the VTOA system. The end office building includes multiple T-IWFs, and a switch that distributes calls among the T-IWFs in a load sharing manner. Each T-IWF has a plurality of processors and is part of the VTOA system. A switch management system is also provided in the VTOA system. In order to reduce and survive failures, the switch management system includes a plurality of switch management system units. At least one of the switch management system units is a backup unit for a primary switch management system unit. Each switch management system unit provides application redundancy within itself.

Methods and apparatus for performing non-intrusive network layer performance measurement in communication networks are disclosed. An example method to measure network layer performance between existing network nodes disclosed herein comprises coupling a first intelligent network interface (INI) to an available access port of a first existing network node providing access to a network, wherein the first INI obtains power and input information only from the access port after being coupled thereto, and exchanging test messages between the first INI and a second INI coupled to a second existing network node during normal operation of the first and second existing network nodes to measure network layer performance, wherein the test messages originate in the first INI and are routed through the first and second existing network nodes using a first network layer address associated with the first INI and a second network layer address associated with the second INI.

A synchronous optical network (SONET) demarcation device can be placed on a customer premises to enable remote testing and trouble shooting of customer premises equipment. The device includes a SONET signal analyzer that extracts SONET data, such as section, line and path overhead. The SONET demarcation device also includes a SONET fault condition, performance statistics, and alarm generator that generates fault conditions, performance statistics, and alarms based upon the extracted SONET data. The device also includes a transmitter that transmits the alarm and/or performance data to a remote site. The SONET demarcation device does not include ring functionality and/or multiplexing functionality, thus being lower in cost than a SONET multiplexer.
