From: "Filiz Eryilmaz" <[email protected]> Subject: Central Site Homologation
Hi Treggers, I have a question concerning Central Site Homologation: If a company wishes to manufacture and sell a Central Site modem rack internationally, what technical requirements beyond the digital specific interface (T1 or E1, a-law or u-law) requirements must he meet? Not withstanding safety and emission requirements are there any country modem-specific operational requirements for such central site modem rack products? Specifically, the bits present at the digital interface to the product represent an analog signal to be reproduced elsewhere in the network. Are there requirements or limits on the bit patterns that the modem rack puts into the network based on the fact that these will be converted to analog signals and sent over the local loop to the end users' (AKA "client") modems? Where would one find these requirements? The product is intended for North America, the European and Asian Pacific markets. Alternatively, could it be that any bit pattern is valid and acceptable and the digital-to-analog conversion equipment elsewhere in the network is responsible for scaling down high-power signals to reasonable limits? Thank you all. Filiz Eryilmaz Lucent Technologies [email protected] tel: (732)9576943 fax:(732)9576878
