Transceiver system and method supporting variable rates and multiple protocols
View Patent ↗Present herein is a multirate transceiver wherein data can be received at a first data rate and transmitted at a second data rate. The transceiver device comprises a first interface for receiving data at one data rate a mapper that can map data from a first rate to the second rate, and a second interface for transmitting the data at the second data rate.
1. A transceiver for transmitting data, said transceiver comprising:
a first interface for receiving data at a first data rate;
a second interface for receiving data at a second data rate;
a third interface for receiving data at a third data rate;
a fourth interface for transmitting the data received at a selected one of first interface, second interface, and third interface;
at least one mapper for mapping data received at the selected one to the fourth data rate, if the selected one is from the first interface and second interface; and
an encoder for DC balancing the data from the third interface, if the selected one is the third interface.
2. The transceiver of claim 1 , further comprising:
at least one demultiplexer for deserializing the data received at the selected one, if the select one is from the first interface and second interface.
3. The transceiver of claim 1 , further comprising:
at least one framer for framing the data received from the selected one, if the selected one is from the first interface and second interface.
4. The transceiver of claim 1 , wherein the data at the first data rate comprises parallel SONET data.
5. The transceiver of claim 4 , wherein the data at the second data rate comprises serial SONET data.
6. The transceiver of claim 4 , wherein the data at the third data rate comprises parallel Gigabit Ethernet data.
