The Onset of Errors technique involves increasing the applied jitter until errors or alarms of any kind are detected by the analyzer s receiver. This technique is used to evaluate electrical interfaces and the ability of circuits, such as synchronizers and desynchronizers in SDH network equipment, to accommodate dynamically varying input data rates. In order to perform jitter tolerance testing accurately and to the required ITU-T standards, the following test equipment requirements must be satisfied. The analyzer should contain fixed jitter tolerance masks covering low- and high-Q systems with peak-to-peak jitter amplitudes and modulating frequencies to ITU-T G.823. For SDH line systems, the fixed jitter tolerance masks are those specified in ITU-T G.958 with a choice of Type A or B masks. The analyzer also must be able to generate the low jitter modulation frequencies and high amplitudes specified in ITU-T G.825, and indeed meet the more stringent requirements of ITU-T O.171 (the jitter measuring equipment standard). It is important that the analyzer be able to perform automatic jitter tolerance testing at the maximum frequency offsets (specified in ITU-T G.703). Clock recovery circuits normally can tolerate large values of jitter at nominal frequency offsets, but this is not usually the case when the recovery circuit is pulled to the end of its frequency range. This provides a realistic measure of an interface s MTIJ by simulating the expected worst-case conditions normally found in a transmission network. ATM traffic also is carried on PDH and SDH physical interfaces, so it is a requirement that ATM networks and network equipment meet the same ITU-T standards for jitter as PDH and SDH network equipment. In order to test jitter and wander tolerance of ATM network equipment, it is essential that the jitter analyzer be capable of generating an ATM signal structure, complete with jitter-generation capability. Jitter problems in ATM networks may manifest themselves in different ways than the traditional PDH/SDH networks. Jitter on an ATM cell stream can corrupt the cell header, causing cell loss and cell misinsertion, and also corrupt the payload, leading to errored cells.

88. The circuit is impulse response stable, not BIBO stable if there is an input resonance. 89. Bounded input, bounded output stability. The circuit has a bounded response given a bounded input. 90. If the input has a frequency that matches the natural frequency of the circuit, there is resonance. Even though there is a bounded input (a sinusoidal function) the output will blow up. 91. |H ( )|dB = 20 log10 |H ( )| 92. A = 2 B 93. s = 1 2 94. = lim tan 1

Table 10.2 illustrates the carrier s perspective on how services can be provided today. In this example, the two 10 Mbps Ethernet circuits cannot be served without the expensive construction of fiber to the two remote sites. Optical equipment, such as SONET or SDH MSPPs, will also be required. The following table shows the inefficiency of bandwidth utilization for the present solution and the inefficient use of bandwidth
