• Description: Programmable Slic
• Manufacturer: Mitel Networks Corporation

Preliminary Information
K1
PR1
simple applications, PR1 can be replaced by a single TVS, such as 1.5KE220C, across tip and ring. For
applications requiring lightning and mains cross protection further circuitry will be required and the following
protection devices are suggested: P2353AA, P2353AB (Teccor), THBT20011, THBT20012, THBT200S (SGS-
Thomson), TISP2290, TSSP8290L (T.I.)
