摘要:
A subscriber network interface for connecting a subscriber premise location to a broadband communication network transporting multiple two-way communication signals, including at least RF analog and RF carrier modulated ATM cells, respectively, includes a coupler for directing incoming communication signals onto, and outgoing signals off of, respectively, at least first and second internal RF communication paths, wherein the first RF communication path includes a bandwidth filter for restricting transmission to, e.g., a CATV broadcast signal, and the second RF communication path is connected to a first modem configured for demodulating and modulating, respectively, the incoming and outgoing ATM cells. A second modem for separately demodulating and modulating, respectively, incoming and outgoing digital baseband signals may also be provided.
