|
EASY TO USE The EZ-TESTER HD is designed to perform in-service monitoring and in-service or out-of-service testing on DS1 and DS3 communications equipment and circuits with a guided easy-to-use menu structure. The EZ-TESTER HD features a large liquid crystal display that can handle hot or sub-freezing temperatures, a water resistant front panel, a built in speaker, and plainly marked front panel LED's, all in a rugged metal case. The LCD screen presents setup options, test results, and configuration setup screens. The test set is equipped with an internal speaker and a 2.5 mm headset connection. An optional noise cancelling headset is available for placing calls and for use while testing in high noise environments. The EZ-TESTER HD comes with the standard industry test patterns built in, and user defined patterns are supported at each transport level. In addition, eight user defined test setups can be entered and are then available at the touch of a button. LINE PARAMETRICS TESTING IS AVAILABLE AS AN ADD-ON OPTION The Line Paramaterics Testing option (Option 40) is used to qualify copper lines used in voice frequency service or digital service applications by measuring the electrical and physical characteristics of the line. The option allows the technician to make line voltage measurements and to analyze the line by measuring electrical characteristics, determining length, and counting load coils. The option includes a time domain reflectometer (TDR) function to locate impedance changes in the line that may indicate physical damage, and a spectrum analyzer function to help detect and identify noise sources that may be causing interference at different point in the T1 bandwidth. Also included are tests to perform noise measurements and to measure the level and frequency of signals present on the line. THE EZ-TESTER HD IS FORWARD COMPATIBLE This means that you can purchase the basic test set in one of several configurations optioned for DS1 or DS3 testing and then add more capabilities as your testing requirements expand without having to replace your unit or suffer expensive and complicated upgrade procedures. Most options are downloadable and only require a modem connection. Downloading is simple, using Electrodata's OnCall® feature built right into the test set. If a hardware upgrade is required, a same-day turn-around in the service center is easily scheduled. Currently, only the addition of MF (option 08) requires a hardware upgrade. Best of all, there is NEVER A CHARGE for software updates to existing options and the basic operating system. Electrodata protects your investment and keeps your cost of ownership low, from the initial purchase through the foreseeable future.
EZ-TESTER HD Options The EZ-TESTER HD is available in three configurations and offers a wide range of options that can be ordered directly or added later as your testing needs expand. The basic instrument :
. DS3 only
. DS3 and Single DS1
. DS3 and Dual DS1
For any configuration which includes DS1, the following options can be added at an affordable price: Fractional T1 (FT1) - (Option 01) The Fractional T1 option provides the ability to test contiguous and noncontiguous 56 x N and 64 x N fractional T1 circuits and equipment. On-Screen Pulse Shape Analysis - (Option 02) With the On-Screen Pulse Shape Analysis option, the EZ-TESTER will provide testing of T1 pulse waveforms. The test set will capture a pulse, measure its basic parameters and compare it to standard pulse masks if desired. For easy interpretation of results, the captured pulse, selected mask and a pass/fail indication are all displayed graphically. ESF / SLC-96 Monitoring and Control - (Option 03) This optional capability allows the monitoring and control of information in the Facility Datalink when ESF framing is used, or the SLC-96 datalink when SLC-96 framing is used. This includes the ability to detect or force PRMs, ASBs and alarms as well as far-end loop commands, maintenance messages and protection switch commands. Performance Statistics Retrieval - (Option 04) The EZ-TESTER HD provides an optional support capability for advanced Network Interface Units (NIUs) which gather performance data at a customer's premises. The EZ-TESTER can retrieve performance statistics and control these devices from an interface at the customer site, from a DSX location in the central office, or through a maintenance switch which supports a non-intrusive connection. Addressable Repeater and Maintenance Switch Control - (Option 05) Loopback and test procedures are greatly simplified when the Addressable Repeater and Maintenance Switch Control option is employed. Command and test sequences are accomplished using the EZ-TESTER HD's commands and its plain language interpretation of responses. Dial / Supervision - (Option 06) This option provides the necessary operations to originate or terminate a call into a digital switch or PBX from a DSX or other T1 access point. It also provides the ability to test Switched 56 services by establishing a data line through the public switched network to a test line or remote DSU/CSU. A user defined sequence of phone number plus access codes can be sent or captured along with signaling events such as a wink, off-hook or on-hook. Computer Enhanced Testing (CET) - (Option 07) The CET option expands the remote control capability of the EZ-TESTER and supports a user friendly environment for the PC user. Electrodata provides software, which operates within Windows®, to control an EZ-TESTER with the CET option. MF Dial/Capture - (Option 08) This hardware option supplements the Dial/Supervision option by enabling MF dial and digit capture with your EZ-TESTER. This option must be installed at the factory. Primary Rate ISDN - (Option 09) This option is used to test Primary Rate ISDN circuits at the central office or at the customer location. It emulates the network or the customer equipment and allows the placing and receiving of either data or voice calls. It will test 23B+D circuit configurations or 23B+D and 24B with the use of the second DS1 line or a second test set). Terminal Emulation - (Option 10) This option allows the EZ-TESTER to interact as a terminal with HDSL and PMDNI Digital Network Interface units both in the central office and in the field. The advantage to you is that a separate terminal or PC is not required to access the wealth of information and capability provided by the HDSL and PMDNI hardware. This option enables field technicians to obtain access to this equipment without having to carry a separate terminal device. DDS Channel Testing - (Option 11) The DDS (Digital Data Service) Channel Testing option allows you to test DDS circuits and equipment from a T1 access point. This option offers full BERT capabilities using DDS-1 through DDS-6 stress patterns and 63, 127, 511 and 2047 pseudorandom patterns. It includes latching and non-latching loopback codes, and has the ability to detect and generate control codes. [Supports 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 Kbps data rates.] GR-303 Test Access - (Option 12) The GR-303 Test Access option provides functions for testing loop access systems as described in Bellcore's GR-303-CORE, "IDLC Generic Requirements, Objectives, and Interface." Capabilities: Captures and displays Time-slot Management Channel (TMC) and Embedded Operations Channel (EOC) data; Filters on layer (2 and 3), CRV, and abnormal cause codes with both pre and post capture capability and timestamps captured messages; Displays raw and decoded hybrid signaling (ABCD) codes. If Option 12 and Option 3 are both installed, GR-303 Test Access will include ESF performance statistics retrieval. If Option 12 and Option 10 are both installed, GR-303 Test Access will provide craft interface access via the RS-232 port. SS#7 Capture / Analysis - (Option 13) The SS#7 Capture / Analysis option provides functions for analyzing Signaling System #7 common channel signaling as described in Bellcore's GR-246-CORE, "Bell Communications Research Specification of Signaling System Number 7" on 56K and 64K SS7 link channels. In the MSU Analysis mode, the test set captures and time-stamps Message Signaling Units (MSU) that appear on the SS7 link channel. Captured messages, selected by pre- and post-capture filtering, can be displayed in detail on an "expanded" screen to show the contents of all available message fields. In the SU/MSU mode, the test set provides running totals on two seperate screens of Signaling Units (SU) and MSUs appearing on the link. During the monitoring period, the test set counts the messages as they are detected and continuously increments a series of counters that show the results as totals, subtotals, and percentage of message types. The SU Analysis mode also displays the number of message re-transmissions by counting inverted Forward Indicator Bits (FIB) and Backward Indicator Bits (BIB). Frame Relay Testing - (Option 14) The Frame relay testing option adds basic test and analysis capabilities to the EZ-TESTER HD for verifying link functionality and connectivity on permanent virtual circuits (PVC). With this option installed, the test set can automatically poll the link to identify the protocol: FRF-LMI, ANSI T1.617-D, or ITU-T Q.993-A, and report the status of DLCIs. The test set will provide real time statistical data for all or individual DLCIs such as total frames detected; number of frame errors; number of FECN, BECN, and DE frames; total octets; and DLCI throughput. This option also enables the test set to test connectivity by initiating and responding to IP PINGs. Add Second DS1 Port - (Option 19) For units configured with a single DS1 test port, Option 19 adds a second port to allow dual line DS1 testing. This option is particularly useful during primary rate ISDN testing, allowing the user to monitor both lines simultaneously, or to perform a drop and insert operation without requiring a seperate receiver to monitor test results. Line Parametric Testing - (Option 40) The line parametric test option allows the technician to identify and isolate physical and electrical problems that may degrade span performance or create safety hazards. The Line Voltage Measurement feature confirms the presence of AC and DC voltage components that may be incorrect for span operation or dangerous to maintenance personnel. The Line Analysis feature identifies dry pair characteristics using line capacitance to compute approximate cable length and detect the presence of shorts. The Level / Frequency Measurements feature is used to determine the suitability of existing cable for T1 and DSL operation. The Noise Measurements feature tests dry pair longitudinal balance to identify the presence of split pairs and similar problems that may impact noise susceptibility. The Spectrum Analysis feature performs a frequency sweep of the line to assist in identifying likely sources of noise interference. The Time Domain Reflectometry (TDR) feature can be used to locate splices or physical damage to lines that causes impedance changes that may diminish line performance. The Test Lead Calibration feature is used to improve measurement accuracy by enabling the test set to compensate for test lead characteristics during measurement calculations. A Cable Charateristics Screen assures more accurate line measurement calculations by allowing the technician to select and enter standard cable types and characteristics during test setup. Available to enhance DS3 testing is: Far End Alarm and Control (FEAC) - (Option 21) The FEAC option allows the test set to display far end alarm and status information via the FEAC channel and to transmit FEAC messages from the near end to test far end responses. The Complete Package The EZ-TESTER HD comes complete with a removable stand, neck strap, technical manual, battery eliminator/charger, printer cable, and a padded carrying case with shoulder strap. Each DS1 option also comes with two six-foot long Bantam-to-Bantam cables and two Bantam to 310 adapters. Each version is covered by a standard three-year warranty.
