... Any telecom equipment submitted to transient overvoltages and lightning strikes such as : Analog and ISDN line cards PABX Main Distribution Frames Primary protection modules DESCRIPTION The CLP200M is designed to protect telecommu- nication equipment. It provides both a transient overvoltage protection and an overcurrent protec- tion housed in a PowerSO-10 FEATURES Dual bidirectional protection device ...

... LCP1511D or THDT series Figure 3 above shows the topology of a protected analog subscriber line at the exchange side. The CLP200M is connected to the ring relay via two balanced Rp resistors, and to the Subscriber Line Interface Circuit. A second device is located near the SLIC : it can be either a LCP1511D or a THDT series ...

... V) GND For surges occuring between TIP and RING, the CLP200M acts in the same way. This means that the CLP200M ensures a tripolar protection. When used alone, the CLP200M acts at the inter- nal overvoltage reference level (+/- 215V). Fur- thermore possible to adjust this threshold level to a lower voltage by using : ...

... OR SW3 SW1 FS In speech mode (Ring relay in position 1), the pro- tection is provided by the combination of both CLP200M and the external voltage reference de- vice. In normal conditions, the working point of this cir- cuit is located in region curve : the CLP200M is idle. When a surge occurs on the line, the external volt- age reference device clamps at GND or -V spectively for positive and negative surges ...

... CLP200M SUBSTRATES AND MOUNTING INFORMA- TION The use of epoxy FR4 boards is quite common for surface mounting techniques, however, their poor thermal conduction compromises the outstanding thermal performance PowerSO-10. Some methods to overcome this limitation are discussed below. One possibility to improve the thermal conduction is the use of large heat spreader areas at the cop- per layer of the PC board ...
