clp30-200b1 technical information 7/15 2 technical information 2.1 introduction the aim of this section is to show the behavior of our new telecom line protection device. figure 13. suscriber line protection topology figure 13. is a simplified block diagram of a subscriber line protection that is mainly used so far. this shows two different things: a ?primary protection? located on the main distribution frame (mdf) eliminates coarsely the high energy environmental disturbances (lightning transients and ac power mains disturbances) for which the itu-t-k20 requires a 4 kv 10/700 s test. this can be assumed either by gas-tubes or silicon protection such as the tlpxxm. a ?secondary protection? located on the line card eliminates finely the remaining transients that have not been totally suppressed by the first stage. the itu-t-k20 requires a 1 kv 10/700 s test. at this stage, the protection is managed by the clp30- 200b1. the explanations which follow are basically covering the line card application. 2.2 stmicroelectronics clp30-200b1 concept 2.2.1 evolution of the slic protection over the years, the performances of the slics considerably increased and therefore the need of the protection has also evolved. the clp30-200b1 is especially designed for the protection of this new generation of slic. for this, it is based on both overvoltage and overcurrent protection modes. telecommunication "primary protection" mdf line card exchange line slic "secondary protection" clp30- 200b1 voltage reference
technical information clp30-200b1 8/15 figure 14. line card protection figure 14. summarises the performance of the clp30-200b1 which basically holds the slic inside its correct voltage and current values. 2.2.2 application circuit figure 15. clp30-200b1 in line card the figure 15. above shows the topology of a protected analog subscriber line at the line card side. a first stage based on clp30-200b1 manages the high power issued from the external surges. when used in ringing mode, the clp30-200b1 operates in voltage mode and provides a symmetrical and bidirectional overvoltage protection above 200 v on both tip and ring lines. when used in speech mode, the clp30-200b1 operates in current mode and the activation current of the clp30-200b1 is adjusted by r sense . programmable thanks to an external resistor programmable thanks to any external voltage reference v i line card operating conditions + i swon -v swon +v swon - i swon rings tip slic overvoltage detector overcurrent detector or or tipl tips ringl gnd sw1 sw2 1 1 2 2 ring generator tip ring ring i r s r s ptc ptc overcurrent detector overvoltage reference (> 200 v) overvoltage reference (> 200 v) overvoltage detector -v bat -v bat external voltage reference r p r p r sense r sense
clp30-200b1 technical information 9/15 a second stage which is the external voltage reference device defines the firing threshold voltage during the speech mode and also assumes a residual power overvoltage suppression. this stage can be either a fixed or programmable device such as lcp1511d. 2.2.3 ringing mode figure 16. switching by voltage during ringing mode in ringing mode (ring relay in position 2), the only protection device involved is the clp30- 200b1. in normal conditions, the clp30-200b1 operates in region 1 of a1 curve, and is idle. if an overvoltage occurring between tip (or ring) and gnd reaches the internal overvoltage reference (+/- 200 v), the clp30-200b1 acts and the line is short-circuited to gnd. at this time the operating point moves to region 2 for positive surges ( region 3 for negative surges). once the surge current disappears, the device returns to its initial state ( region 1 ). for surges occurring between tip and ring, the clp30-200b1 acts in the same way. this means that the clp30-200b1 ensures a tripolar protection. when used alone, the clp30-200b1 acts at the internal overvoltage reference level (+/- 200v). furthermore, it is possible to adjust this threshold level to a lower voltage by using up to 4 fixed external voltage reference (v z1 to v z4 ) (see figure 17. ). overvoltage detector overcurrent detector or tipl tips 1/2 clp200m gnd sw1 1 2 2 1 1 3 - 200 + 200 tip i lg v lg i lg v lg overvoltage reference (> 200 v) r sense a1
technical information clp30-200b1 10/15 figure 17. method to adjust the reference voltage 2.2.4 speech mode figure 18. switching by current during speech mode in speech mode (ring relay in position 1), the protection is provided by the combination of both clp30-200b1 and the external voltage reference device (for example lcp1511d). in normal conditions, the working point of this circuit is located in region 4 of a2 curve: the clp30-200b1 is idle. when a surge occurs on the line, the external voltage reference device clamps at gnd or - v bat respectively for positive and negative surges. this generates a current which is detected by r sense and causes the protection to act: the line is short-circuited to gnd. the operating point moves to region 6 for positive surges or region 5 for negative surges. rings overvoltage detector overcurrent detector or or tipl tips vz1 vz3 vz2 vz4 ringl gnd gnd sw1 sw2 1 1 2 2 tip ring overcurrent detector overvoltage reference (> 200 v) overvoltage reference (> 200 v) overvoltage detector r sense r sense overvoltage detector overcurrent detector or tipl tips gnd sw1 1 2 6 4 5 tip i lg v lg -v bat i lg v lg -v bat overvoltage reference (> 200 v) r sense external voltage reference r p
clp30-200b1 technical information 11/15 once the surge current falls below the switching-off current i swoff , the clp30-200b1 returns to its initial state ( region 4 ). furthermore, the clp30-200b1 switches when an overvoltage, either positive or negative, occurs either: simultaneously on both tip and ring lines versus gnd between tip and ring on tip (or ring) versus gnd the choice of the switching-on current is function of the r sense resistors. this current (typically above 150 ma) should not activate the protection device clp30- 200b1. therefore the level of activation is to be chosen just below this limit (typically 200 ma). this level is adjusted through r sense . figures 7a and 7b enable the designers to choose the right r sense value. example the choice of r sense = 3 ? ensures a negative triggering of -280 ma min and -380 ma maximum. in this case, the positive triggering will be 220 ma min and 320 ma max. thanks to the clp30-200b1 topology, the surge current in the line is reduced after it. because the remaining surge energy is low, the power ratings of r p , the relay contacts and the external voltage reference device may be kept low. this results in a significant cost reduction for the whole system. figure 19. switching-on current versus r sense : relative variation of i swon versus r sense at various temperature figure 20. switching-on current versus r sense : relative variation of i swon versus r sense at t amb = 25 c 2345678910 100 200 300 400 500 600 r() sense ? i (ma) swon i @ 0 c swon i @ 25 c swon i @ 70 c swon i @ 25 c (ma) swon 357911 100 200 300 500 r() sense ? imin negative swon imin positive swon imax positive swon imax negative swon
