SONET for the field

Lightweight, handheld, and ruggedized, the SunSet OCx is uniquely suited for field applications. The OCx gives you long battery life and a color display that is easily readable under all lighting conditions, indoor and outdoor. The OCx has the power and features you would expect from a benchtop box in a platform you can take anywhere.

Applications for the field technician:

• Verify network continuity
• Easily detect SONET errors and alarms with LEDs and well-organized results screens
• Monitor pointer movement in the network or adjust the pointer values to stress network elements

APS Timing
Automatic Protection Switching is an important, mission-critical function o SONET. The SunSet OCx allows you to qualify this vital system by measuring the time it takes for a working circuit to switch to the protection circuit. The user can select the desired switch and gate times and the OCx will give a clear pass/fail indication along with the time measurement.

• Sensors and Switching Criteria:
• Line and Path AIS
• Line Parity Errors (B2)
• DS3 Errors

The SunSet OCx also measures the duration of service disruptions & loss of pattern with millisecond resolution.

SONET Overhead Control
Nearly five percent of the SONET frame is dedicated to overhead. This overhead includes important network properties such as parity (B1, B2, B3, and VTBIP-2), protection switching (K1, K2), pointers (H1-H2), network status (S1, G1, V5), and defects (AIS, RDI, REI, etc.).

The SunSet OCx gives you easy access to the entire section, line, path, and virtual tributary path overhead, displaying the hex values and their decodes. The OCx also provides control of transmitted overhead bytes, pointer values, and pointer movement.

SONET Overhead Highlights

• Decode/encode of overhead bytes
• Display & modify traces (J0, J1, J2) as text characters
• Data Communications Channel (D1-D3, D4-D12)
• VT1.5 overhead control (V1-V5, J2, etc.)

Comprehensive T-Carrier Testing

Just because the SunSet OCx is designed for high speed optical rates and data-centric protocols like ATM does not mean that you need to sacrifice the traditional T-carrier applications. In fact, the SunSet OCx offers all the transmission testing applications for T1 and T3 circuits.

Loopback Control
Loopback testing is a vital tool for circuit turn-up and troubleshooting. The SunSet OCx provides a variety of options for looping DS1 and DS3 circuits, allowing technicians to isolate a fault quickly from a single location, saving time and truck rolls.

• In-band and data link codes
• Addressable repeaters (Westell/Teltrend)
• HDSL loopbacks
• DS3 and DS3/DS1 FEAC codes
• Easy-to-read diagrams

The OCx can also emulate CSU or NIU equipment and respond to loopback commands.

DS1 Testing Features
The SunSet OCx comes standard with a variety of easy-to-use tools for testing DS1 networks.

• View Received Data shows all 24 timeslots over 20 DS1 frames—ideal for seeing in-band alarms and messages, identifying an ISDN D-Channel, or looking at simple test patterns.
• Quicktest I/II allows a technician to program a variety of test patterns for a set duration. At the end of the test, the OCx provides the test results for each pattern as well as a clear pass/fail indication. Quicktests can also automatically loop up and loop down the circuit.
• Bridge Tap Detect uses specialized test patterns to determine if bridge taps are on the line.
• Propagation Delay provides the roundtrip delay of a test pattern through the DS1 network.

Pulse Mask Analysis
The pulse mask feature gives you a quick and powerful tool to analyze and qualify a DS1 or DS3 circuit. Physical layer problems become readily apparent, making for quick fault diagnosis.

The SunSet OCx measures the shape and key parameters of the pulse, displaying the pulse on the screen. The OCx then compares the shape to predefined templates based on governing standards and provides an easy-to-interpret pass/fail test.

DS1 Data Link
Monitoring the DS1 Data Link is an excellent way to discover errors which otherwise could not be detected at your monitoring point. Decodes of bit messages provide valuable information such as alarms and protection switching. Performance reports provide a comprehensive snapshot of the health of the circuit.

The SunSet OCx monitors and decodes both bit and performance report messages. The OCx also transmits bit codes selected by the user or performance reports compiled from its own measurement results.

DS3 FEAC
Monitor and transmit messages carried by the Far End Alarm and Control Channel used in C-bit framing to provide circuit status and loopback control.

ATM Features

The SunSet OCx 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 from T1 to OC- 48c are available in one chassis, eliminating the need for multiple ATM test sets. The full-featured ATM testing capabilities of the SunSet OCx provide the power and flexibility to install and troubleshoot an ATM network from the ground up. The OCx can test and monitor transmission between separate network elements (NNI) or between the network and edge devices. Here it can verify network provisioning; perform stress tests; conduct BER testing; and monitor responses to alarms, errors, and OAM cells. The SunSet OCx allows you to nonintrusively monitor traffic across the network, gathering statistics on congestion, bandwidth, idle cells, OAM cells, and errors.

Any SONET 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 on finger pointing.

Traffic Generation

• Generate multiple independent VCCs. With the SunSet OCx, you can program up to eight independent VCCs, each with their own traffic pattern and payload, up to 100% of your ATM network capacity. The OCx supports O.191 test cells or user cells with pseudo-random or 16-bit patterns.
• Insert Errors and OAM Cells. Inject bit errors, HEC errors, or OAM Fault Management cells into your generated traffic.

Traffic Supervision

• VCC Scan. View the traffic moving across the network including the cell header and bandwidth. Filter on VPI or select one or more VCCs for more detailed traffic statistics.
• BERT and Quality of Service (QoS). The SunSet OCx supports QoS measurements, such as cell delay variation, cell loss ratio, and bit error rate testing.
• Capture and store cells. Save, view, decode, and analyze user and OAM cells. Decode the ATM header and OAM function fields.

DSL Testing Highlights

• Automatic detection of SunSet xDSL
• Independent upstream and downstream rates
• Bit error rate and throughput testing
• ATM over SONET and T-Carrier out of the DSLAM

DSL Testing

As DSL becomes widely deployed, DSLAM (Digital Subscriber Loop ATM Multiplexer) installation verification is becoming more critical in ensuring proper functionality. However, when the full backbone is not operational, only limited testing can be achieved. To solve this problem, Sunrise Telecom has developed an innovative test solution for DSLAM turn-up verification.

The SunSet OCx works hand-in-hand with the SunSet xDSL to perform dualended, asymmetric ADSL qualification. These tests not only allow you to verify installation, but also the qualification of the Optical Carrier and the DSL copper pair simultaneously. This help qualify DLC (Digital Loop Carrier) Systems and verify proper provisioning of the remote DSLAM.

ATM IP Testing

The predominant application for ATM networks, especially for DSL services, is the Internet. Testing the IP layer is critical for qualifying an ATM connection. Though it only takes a few minutes, the IP PING test can qualify not only the ATM network, but reach through Ethernet, Packet over SONET, and other IP-centric networks.

ATM/IP Testing Highlights

• RFC 1483 Bridged and Routed, PPPoA, and P PoE
• Static and dynamic addresses
• PING generation and automated PING response
