IP Testing The IP module provides an efficient way to verify end to end provisioning from the customer ADSL modem to the far end ISP gateway and beyond. PING Test: Verifies provisioning and IP connectivity all the way to the customer's ISP. The IP module offers Service Level Agreement (SLA) verification between the ISP and the customer. This verification is critical for business customers with minimum bandwidth guarantees. Throughput Test: This application is designed to verify the available upstream and downstream bit rates between the ISP gateway and the customer premises. The SunSet user can generate a specific load, measure the quality of the transfer, and determine the bit rate limit separately in each direction, thus verifying the SLA separately for both upstream and downstream transmission. This asymmetric load test is superior to ATM cell loopback methods of other

15 vendors which can only verify connectivity but cannot verify full bandwidth asymmetric transmission in both upstream and downstream directions. Datacom Testing The Datacom module expands the SunSet xdsl's applications to testing WAN/data services. DTE/DCE emulation extends end-to-end testing of data networks and can be used to install and verify CSUs, routers, and other WAN equipment at the CPE. B-directional monitoring provides a greater level of troubleshooting for data networks. Applications include: DTE/DCE emulation Bi-directional monitoring with Y-adapter V.35, RS232, RS449, RS530, X.21 Data rates from 50 bps to Mbps BERT testing with stress patterns Control lead status for CTS, RTS, DSR, DTR Loopback testing with RL & LL DTE Emulation DTE emulation provides end to end testing for data networks. This can be done in either a point to point configuration or the set can loopback a DCE device (RL & LL) for one-sided testing.

16 Bi-directional Monitoring With Y-adapters the SunSet xdsl can monitor the data sent by the DTE and DCE devices. Users may view control lead status (CTS, RTS, DSR, DTR) from both sides, as well as view the actual data bits sent. Other valuable monitor measurements include data loss and received frequency. VF-TIMS Testing VF-TIMS module offers as an additional application to the SunSet xdsl product. The VF-TIMS module provides complete Voice Frequency testing in the analog voice range. It supports a range from 50Hz to 20,000Hz, and has tests for received level and frequency, noise, signal to noise, impulse noise, and call setup (DTMF, DP, or MF Dialing). Applications include: Transmission/Receive Frequencies and Level measurements 3-Tone Slope and Frequency Sweep functions Noise and Signal to Noise ratio Measurement Impulse Noise measurement Call Placing for Analog circuit testing Transmission /Receive Frequencies and Level measurement One basic application is to transmit a frequency over a pair of wires. Typically another test set is needed to measure the frequency at the far end of the cable. This function of transmitting frequencies includes a number of ways this can be done: 1. Fixed Mode: This is a single fixed frequency being sent at a fixed level Tone Slope Mode: This mode sent frequency 404, 1004, and 2804 Hz at 5 seconds interval with a fixed level. 3. Sweep Mode: This sweeps a certain range of frequencies with a user configurable start and stop frequencies, a step, a dwell time, and a fixed level. 4. Quiet Mode: This places a quiet termination on the circuit. Another basic application is to receive a frequency and perform a level measurement. This

17 strictly shows received frequency and level. Noise and Signal to Noise ratio Measurement, and Impulse Noise Measurement VF-TIMS module can perform Noise and Signal to Noise ratio measurement, and Impulse Noise measurement with different filters placed on receiver. These filters are C-message, 3kHz-Flat, and 15kHz-Flat. This test is typically done on one of the cable with a Transmit source on the other end of the pair, and this test can be done either 2-wire or 4-wire cable. Call Placing for Analog circuit testing VF-TIMS module allows you to place a call on a 2 wire analog POTS circuit with selected dial mode (DTMF, DP, or MF dialing). This will be done connected to a switch in a central office where digits are sent and you can talk and listen with the test on line.
