Jason, I just dug this out of my e-mail stuff. I don't have an answer but as part of the UL family you should have access to UL's ICS (International Compliance Services) group who routinely track things like this down for clients and UL staff. Check with Mike Caruso on the best way to go about this (i.e. which office, who to contact, etc.)
Randy Ivans Underwriters Laboratories Inc. Business Sector Coordinator Telecommunications Industry email: [email protected] ------------- Original Text From: "Jason Chesley" <[email protected]>, on 12/1/98 7:41 PM: Can anyone help me catagorize and determine the appropriate EU directives and standards for the following product descrption? Also, does it require a Notified Body to be involved (witnessed?) and if so can the testing be done in the states? Product description: Five amplifier products requiring CE marking; Low Noise Amplifier and Diplexer, Controller, HPAA, MHU and MHUI. These products are used in a 3.5GHz band wireless local loop system which is essentially a "non-mobile" cellular system used to provide voice and data communications links to businesses and residences without wire. Setup: One config would be the customer provided antenna (Tx/Rx) would be connected to the MHU, both of which are located outside. The MHU is, in turn, connected to the MHUI indoors. All of this equipment is connected via coax (48VDC & RS-485 - Tx/Rx) Another config would be the customer provided antenna (Tx/Rx) would be connected to a couple of Low Noise Amps and Diplexers all of which is located outside. The LNAs and Diplexers are, in turn, connected to the controller and two HPAAs indoors. All connections coax. Info: HPAA - RCS high power amplifier. Amplifies RF input signal only - no modulation or signal generation is done. Does not interface with the Public Telephone Network. MHU - Mast Head Unit. Amplifies RF signals in the receive and transmit (Rx/Tx) directions. Provides a LNA in the Rx path, amp in the Tx path. Diplexers put Rx/Tx on one coax. Does not interface with PTN. MHUI - Mast Head Unit Interface. Interfaces the MHU to the customers communication equipment. No PTN interface. It's possible I left out some needed information to assess this equipment properly, if so please ask. Any help is greatly appreciated. Thank you, Jason L.
