This interpretation came from the FCC and a Notified Body - in the course of numerous discussions on this subject, may I say. Regards, Bandele Jetstream Communications, Inc. [email protected]

To wit: "outside" is easily enough understood as a line (presumed metallic) that enters a building structure from an uncontrolled environment and subject to transients. Direct implies to me that there is no interposing hardware, other than interconnects (no voltage surge suppression devices, galvanic isolating equipment, etc). Is this an interpretation from a Notified Body or known to be the intent of the standards committee that wrote the requirement? Regards, Peter L. Tarver, PE [email protected] -----Original Message----- From: Bandele Adepoju Sent: Thursday, August 31, 2000 1:16 PM Hello Debbie, If the jack has processing capabilities (if it takes the incoming data signal and reprocesses it or reformats it), any connection to it is considered to be an "indirect" connection. If the jack does not have processing capabilities (if it passes the data signal straight through), any connection to it is considered to be a "direct" connection.
