Dear Duane, If the modem is connecting to a phase 1 GSM phone then there are no requirements for testing the GSM aspects. However, if the modem is intended to connect to a phase 2 GSM phone then it's a different story. If the modem is able to modify terminal performance or implements some of the regulated aspects of the GSM functionality then testing and type approval are required. Such a modem will be classed as a regulated accessory and testing will need to be performed against TBRs 19 and/or 20. The TBRs refer off to ETS 300 607, which is effectively the GSM 11.10 document. If you wish to find out more information then a good contact is Les Rowland of BABT (tel: +44 1932 251200, fax: +44 1932 229756, email [email protected]). I hope that this information is helpful. regards, Chris Foot -------------------------------------------------- Chris Foot Tel: +44 (0) 1256 316800 Approvals Engineer Dir: +44 (0) 1256 316807 Communicate Limited Fax: +44 (0) 1256 477600 London Road Old Basing Basingstoke Hampshire RG24 7JL UK Any and all known disclaimers apply --------------------------------------------------
