FCC P 68 UL 60950 FCC P 68 UL 60950 UL 497 GR 1089 UL 60950 UL 497 GR 1089 UL 60950 UL 497 GR 1089 UL 60950 Application of Regulatory Requirements Central Office Outside Plant Subscriber Premises MDF SLIC switch DDF Customer Premise Equipment (CPE) Street Cabinet SLIC APP if on DLC system O/H Cable U/G Cable Wall Plug, Network Interface Device (NID) POTS SPLITTER SLIC MDF trunk line T1, HDSL, or HDSL-2

4. Regulatory Requirements • GR 1089 Issue 3 Oct 2003 • Electrical safety (surge and current limiting) • LEC offices and CPE locations • TIA-968-A • Lightning • Customer premises equipment (CPE) • UL 60950 • surge • power cross

5. Regulatory Requirements • ITU K.20/21 • Metallic and longitudinal surges • Power Cross • Coordination issues

6. ITU K.20/21 • K.20 covers central office type of equipment • K.21 covers customer premises type of equipment • Two levels: • Basic • Enhanced

7. ITU K.20 surges • BASIC applied ± 5 times • 5x310 25A for single port w/o primary • 5x310 37.5A for multiple port application w/o primary • 5x310 100A must coordinate w/primary • ENHANCED • 5x310 37.5A for single port or multiple port w/o primary • 5x310 150A to eliminate need for primary

8. ITU K.21 surges • BASIC applied ±5 times • 5x310 37.5A for single port or multiple port w/o primary protectors • 5x310 100A must coordinate w/primary • 8x20 1 kA to eliminate need for coordination • ENHANCED • 5x310 150A for single port or multiple port w/o primary protectors • 5x310 150A must coordinate w/primary • 8x20 5 kA to eliminate need for coordination

9. ITU K.20/21 coordination • Coordination with the primary • not required for BASIC IF: • capable of withstanding 8x20 1kA surge ± 5X • not required for ENHANCED IF: • capable of withstanding 8x20 5kA surge ±5X • Coordination not required if primary is not “specified” (the agreed to primary protector clause)

10. ITU K.20/21 Power Cross • BASIC • 600 volt, 1A for 1 second • ENHANCED • 1500 volt, 7.5A for 2 seconds • AND a series of 15 minute tests at 230 volts with 10,20,40,80,160,300, and 600 ohm test resistor (fuse allowed to open for BASIC and first 4 conditions for ENHANCED)

11. SIDACtor - What is it? • Over-voltage Protection For: • Telecommunications Equipment • CATV Equipment • Security Systems • Data Communications • Thyristor Applications

12. SIDACtor - How Does it Work? • Turns on with voltage • Turns off with current

13. SIDACtor - How to Select • Vdrm > Peak (DC) operating voltage of protected circuit • Vs > Withstand voltage of protected circuit • Ih(MIN) > Short circuit DC current of protected circuit • Ipp > Anticipated surge current of regulatory requirements

14. SIDACtor V-I Curve +I IT IS IH IDRM -V +V VT VDRM VS -I

15. TeleLink Fuse - over current protection • A surge tolerant fuse element • Surface mount package • 1.25A current rating for F1250T • .5A current for F0500T • Helps applications comply with: • UL 60950 • GR 1089 • TIA-968-A

16. Application Circuits • T-1/E-1 • T3 • ADSL/ xDSL • VDSL intra-building • VDSL inter-building • SLIC (subscriber line interface circuit)

17. Application Circuits • SLIC (subscriber line interface circuit) • Ethernet 10/100 BaseT • ISDN • Transformer Protection
