This Technical Note provides you with detailed instructions for setting up lightning arrestors to protect your Motorola PTP 400 and 600 Series bridges. The recommendations provided in this Technical Note will provide the best protection from the harmful effects of electro-magnetic discharge (eMd). The Surge Arrestor (ALPu-orT) should be used on all PTP 400 and 600 bridge interface ports, including the ethernet, T1/e1 and power ports.
