T1E1J1电路保护

设计说明 


  

保护应用: 
T1 / E1 / J1 lines are concentrated digital phone lines with bit rates of up to 2.0 Mbps. The data signals are low voltage but "phantom" powering schemes are often employed (as shown). 
解决方案说明: 

Two CO end options are shown. Each requires a ground referenced solution. The top is an unbalanced solution using 4 DO-214 devices and the bottom is a balanced one using a single 6-Pin SMT package. Regenerators are not ground referenced and use a simple metallic protection scheme as shown on the right. TeleLink保险丝为常用元件。 
配套解决方案: 
Other packaging solutions are offered within the Ruilon portfolio. For instance, all four P1800SC can be replaced by a single P1804UC. Thru-hole packages (TO-92's and TO-220's) also are available. 
监管问题: 
This solution is designed to comply with Telcordia's GR-1089 inter-building requirements. 
特性:Ruilon is the only vendor offering the 6-Pin MS-013 surface mount package. 
应用警告:不适用。
