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

ITU K.20 surges BASIC applied ± 5 times ENHANCED 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

ITU K.21 surges BASIC applied ±5 times ENHANCED 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

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)

ITU K.20/21 Power Cross BASIC ENHANCED 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)
