Abstract

A terminal for use with telecommunication cables has a splice closure and a terminal closure joined to the splice closure. The splice closure encloses opened areas of the cable, while the terminal closure encloses a connection device for establishing connection between telecommunication lines in the splice closure and a drop line. In various embodiments, a frame is mounted within the splice closure for retaining non-spliced lines of the telecommunication cable away from spliced lines; a storage member is located within the terminal closure for retaining excess lengths of the drop line; a drop line strain relief bracket is mounted within the terminal closure; and a memory device is incorporated into the terminal for storing information about the terminal.
