Abstract: A small form-factor transceiver module performs protocol translation, in addition to the conventional electrical and/or optical transmission media conversion. Such protocol conversion may enable transport of traffic from limited-range primary networks over long-range secondary networks, such as extension of Ethernet networks over low-rate TDM links. Additionally, such protocol conversion may enable interworking between different networks of differing technologies, such as transport of ATM traffic over Ethernet networks. The transceiver module may be a Small Form Factor transceiver (SFF), Small Form Factor pluggable module (SFP), Gigabit Interface Converter (GBIC) or any similar small form-factor module consisting of a housing, internal electronic circuitry and optionally optical components, and associated electrical or optical connectors. The transceiver module performs protocol translation by means of an integral protocol translation unit that performs standards-based or proprietary conversion between network protocols.

Abstract: A method and system in which a Digital Subscriber Line Access Multiplexer (DSLAM) that is part of a DSL (Digital Subscriber Line) system is able to provide synchronous services to end user equipment connected to the DSLAM via a DSL link and Customer Premises Equipment (CPE). A sniffer device having direct or indirect access to a Primary Reference Clock (PRC) of the DSL system calculates the phase difference between the PRC and the DSLAM's Local Timing Reference (LTR). The phase difference is sent to the CPEs requiring accurate reference clock frequency. The CPEs are able to derive the PRC from the phase difference information transmitted by the sniffer device thus enabling synchronous end user equipment operation.
