Dial-up

Circuit Protection of Dial-Up

Solutions:

Solutions:

Protection Application:: The signals carried on the tip and ring lines by dial-up circuits operate up to 56,000 bits/sec., so the capacitance of the protection device does not need to be controlled. The electrical threats include lightning surges and Power Cross conditions
Solution Description:: As shown at the left, a fuse or PTC can be used for Power Cross protection, and a SIDACtor® thyristor for lightning surge protection. The specific part numbers are determined by matching the operating voltage, and surge’s peak pulse current value to that of the surge suppressor.

Regulatory Issues:: In customer premises equipment like computers and set top boxes, there are a number of safety and performance-based Regulatory standards that apply. These include: TIA-968 GR-1089 ITU K.20, K.21 UL 60950/EN 60950
