Z-BLOCKER® Z-300TJ xDSL over POTS In-Line Filter Description The Z-300TJ is a small in-line filter designed to expedite the service delivery and improve the performance of digital subscriber line (DSL). This model fits all telephone sets, facsimile machines, answering machines, etc. individually or in groups. It also provides a second convenience jack that is unfiltered for connecting DSL. This in-line DSL filter design electronically isolates the highspeed DSL data streams from the voice band plain old telephone services (POTS) equipment. This design effectively blocks the DSL, and other radio frequencies from 25 kilohertz to 30 Megahertz. Features ● Data Protection - Isolates telephone equipment impedances from DSL equipment ● Excellent DSL band attenuation that protects voice band equipment and prevents intermodulation distortion from degrading data rates ● Compaible with all major DSL standards including ADSL, ADSL+2, VDSL, and VDSL2 ● Voice Protection - Isolates DSL band frequencies from voice band equipment The Z-300TJ provides a DSL convenience jack for connecting a DSL modem Applications The Z-300TJ filters are used with other Z-BLOCKER® filters distributed throughout the subscribers' premises to isolate all voice band equipment devices such as cordless telephones, answering machines, fax machines, dial-up modems, and television set-top boxes. The Z-300TJ in-line DSL filter is one of many filters manufactured by Excelsus for subscriber installed digital services within homes, offices, and hotels. Excelsus is the number one selling brand of DSL filters worldwide. ● Excellent longitudinal balance ● Compatible with Caller ID, facsimile and metallic loop testing ● RoHS compliant ● Compliant and listed with UL 60950, FCC Part 68 ● CE certified Z-300TJ Block Schematic www.PulseElectronics.com EX109.A (02/12) Z-BLOCKER® Z-300TJ xDSL over POTS In-Line Filter Z-BLOCKER® Z-300TJ Filter Specifications Line side differential input blocking impedance At 20 kHz At 30 kHz From 5 MHz to 10 MHz 1 kHz insertion loss between 600Ω resistive Single filter With 5 filters 1 kHz/2.8 kHz slope between 600Ω resistive Single filter With 5 filters DC resistance in Ohms Tip to Tip, and Ring to Ring Tip to Ring Longitudinal Balance per IEEE method From 200 - 1 kHz From 1 kHz - 3 kHz Common mode rejection at 40 kHz and 30 MHz Low pass roll off (slope) between 600Ω and ADSL Transmission Unit - Remote Inter-Modulation Distortion First and Second order products Envelope Delay 300 Hz - 2800 Hz 600Ω Return Loss into phone side with 600Ω line termination with ATU-R Single filter SRL Low ERL SRL High +2 bridged filter SRL Low ERL SRL High +4 bridged filter SRL Low ERL SRL High Complex* Return Loss with ATU-R Single filter SRL Low Single filter ERL Single filter SRL High +2 bridged filters SRL Low ERL SRL High +4 bridged filters SRL Low ERL SRL High * 1330Ω in parallel with (100nfd in series with 348Ω) DC Loop Current - Meets specifications between 20 and 100 milliamps DC Connectors: RJ-11 Jack and RJ-11 Plug RJ11 pins have ≥50 micro-inches of gold plating over ≥100 micro-inches of nickel plating Dimensions: Length 53mm, Width 19.75mm, Height 18.9mm (Cord length:75mm) Compliant and listed with UL / CSA 60950, FCC CFR 47 Part 68 >2k >3k >2k <0.4 <0.6 <0.1 <1.1 <12 >10M >58 dB >53 dB >45dB >26dB >60dB <100μs >30dB >14dB >17dB >36dB >23dB >13dB >26dB >15dB >8dB >27dB >14dB >6dB >19dB >14dB >3dB >15dB >7dB >2dB Pulse Singapore - 135 Joo Seng Rd.#03-02PM Industrial Bldg.Singapore 368363 Tel: +65 6287 8998 Pulse Taiwan - 3F, #198, Zhongyuan Rd., Zhongli City Taoyuan, County 32068, Taiwan Tel: +886 3435 6768 Pulse US - 12220 World Trade Drive, San Diego, CA. 92128 Tel: +1 858 674 8100 www.pulseelectronics.com Specifications subject to change without notice.
