Make: JDSU Model: HST-3000 SIM CUADSL2-TX ANX A2 Testing Module Part Number: -- Description: This listing is for a USED JDSU HST-3000 SIM CUADSL2-TX ANX A Testing Module. I have a quantity of these items available. These modules were received in a bulk surplus purchase and have been fully tested and inspected for functionality issues and found to be in good working condition. All are in similar cosmetic condition to the one shown in the photos. Listed below is an overview of some of the features and benefits this product has to offer: JDSU HST-3000 SIM CUADSL2-TX ANX A Module (Copper, ADSL, & ADSL2 Testing For Annex A) For Use With The HST-3000 The HST’s copper testing features allow quick turn-up and troubleshooting of the services provided over copper. This includes testing with DVOM, opens, power (Mains) influence (PI), noise, balance, time domain reflectometer (TDR), resistive fault locate (RFL), load coil detect, loss, wideband transmission impairment measurement set (WBTIMS), caller ID, and POTS dialer. The HST provides process customization through on-board auto tests and allows workflow improvements via connectivity to craft access terminals and back-office systems. The copper testing features include the following: Measuring AC and DC voltage, current, and resistance Measuring to opens (length of cable) Measuring balance, noise, and power (Mains) influence (PI) Locating cable faults with the TDR or RFL Detecting load coils Measuring loop loss (voiceband) including receiving and sending tones; transmission impairment testing (noise, SNR, return loss) Voice service and caller ID (CLID) testing WBTIMS and WB2 TIMS testing including sending/ receiving tones; measuring wideband, impulse, and spectral noise; and transmission impairment testing (noise, SNR, return loss, crosstalk) Automatic testing using scripts, including POTS close out, good pair check, and wideband auto tests. ADSL is designed to carry a digital signal, over a copper pair, above the voice frequency band (20 KHz–1.1 MHz) to enable high speed internet service over a standard POTS line. This allows “always on” internet access while simultaneously providing voice service. Typical POTS line quality will normally support ADSL, but the DSL service must be tested when trouble strikes. To troubleshoot DSL service, a modem emulation test set, such as the HST-3000, is needed. The DSLAM and network configuration is verified by connecting at the main distribution frame (MDF) where known interference and attenuation are minimal, as shown in Figure 1. The physical (ADSL) layer data rates and noise margins are reviewed to confirm that they match the service contract. Validate correct DSLAM and BRAS provisioning by connecting to the customer line and authenticating with the network through the DSLAM. Functionality: Tested and Working Condition: Accessories: Used; minor cosmetic damage, scuffs and scratches (shown in photos) Not included.
