Any SDH, PDH, or T-carrier network provisioned for ATM traffic needs to be qualified for ATM. If you lease your network to service providers using ATM, you need a tool to test, verify and troubleshoot the network and the traffic it is carrying. Conversely, if you are responsible for the ATM traffic, you must verify that the network is error free and functioning properly, especially when you do not own the network. When traffic is disrupted, you cannot waste valuable time and money pointing fingers.

The SunSet SDH is the single testing solution for both the physical layer and the ATM layer. With one test set, a single technician can verify network performance with and without ATM traffic. All applicable network rates, up to STM-16, are available in one chassis, eliminating the need for multiple ATM test units if the ATM network spans several subnetworks. The full-featured ATM testing capabilities of the SunSet SDH provide the power and flexibility to install and troubleshoot an ATM network from the ground up. The SunSet SDH can test and monitor between network elements (NNI) and the network and edge devices (UNI). It can verify network provisioning, perform stress tests, conduct BERT analysis, and monitor responses to alarms, errors, and OAM cells. The SunSet SDH allows you to non-intrusively monitor traffic across the network, gathering statistics on congestion, bandwidth, idle cells, OAM cells, and errors . Its ATM IP and INARP capabilities can verify connectivity between network devices, like a 3G Node B and RNC.

Traffic Generation Generate one to eight independent VCCs. Perform up to eight separate traffic tests at once. Programmable traffic pattern: CBR, UBR, VBR, Sequential Cell with user or O.191 test cells. Insert OAM cells: F4/F5, Segment/End-to-End, FM cells. Verify the alarm and loopback response of ATM network elements. Inject errors: BIT, HEC, and NC-HEC errors. ATM Dual-ended BERT and Throughput testing with the SunSet xDSL and SunSet MTT.

Traffic Supervision Scan 128 VCCs for header information. View the traffic moving across the network including the addresses and cell loss priority. Select suspicious streams to filter and analyze. Traffic Monitoring. BERT, Quality of Service (QoS), and OAM measurements. The SunSet SDH compiles vital network information following O.191. Comprehensive cell testing measures cell count, cell congestion, cell bandwidth, cell loss, cell error ratios, cell delay, and cell delay variation. Users can also view the number and total time of OAM events such as AIS and RDI alarms (also displayed in a histogram format).

Cell Capture & Decode Capture and store cells. Save user and/or OAM cells. View, decode, and analyze saved cells at any time. Header decode. The SunSet SDH displays the meaning of the header values, including general flow control (GFC), VPI/VCI, payload type indicator (PTI), and cell loss priority (CLP), plus any timestamps and sequence numbers. OAM cell decode. The SunSet SDH can decode all forms of OAM cells. Decipher the location IDs for AIS, RDI and loopback cells. Generate important PM statistics like total received cell count and block error results. Verify the activated PM block size.
