TRANSCEIVER SYSTEM AND METHOD SUPPORTING VARIABLE RATES AND MULTIPLE PROTOCOLS
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 method for transmitting data, said method comprising:
receiving data at a first data rate;
mapping said data to a second data rate; and
transmitting data mapped to the second data rate.
2 . The method of claim 1 , wherein the first rate comprises a rate selected from SONET, Gigabit Ethernet, OC-3, OC-12, and OC-48.
3 . The method of claim 2 , wherein the second rate is lower than the first rate.
4 . The method of claim 1 , further comprising:
deserializing the data received at the first rate; and
serializing the data transmitted at the second rate.
5 . The method of claim 1 , further comprising:
generating frames comprising said data.
6 . A transceiver for transmitting data, said transceiver comprising:
a first interface for receiving data at a first data rate;
a mapper for mapping said data to a second data rate; and
a second interface for transmitting data mapped to the second data rate.
7 . The transceiver of claim 6 , wherein the first rate comprises a rate selected from SONET, Gigabit Ethernet, OC-3, OC-12, and OC-48.
8 . The transceiver of claim 6 , wherein the second rate is lower than the first rate.
9 . The transceiver of claim 6 , further comprising:
a demultiplexer for deserializing the data received at the first rate; and
a multiplexer serializing the data transmitted at the second rate.
10 . The transceiver of claim 6 , further comprising:
a framer for generating frames comprising said data.
11 . A transceiver for transmitting data, said transceiver comprising:
a first interface receiving data at a first data rate;
a mapper connected to the first interface, wherein the mapper maps said data to a second data rate; and
a second interface connected to the mapper, wherein the second interface transmits data mapped to the second data rate.
12 . The transceiver of claim 11 , wherein the first rate comprises a rate selected from SONET, Gigabit Ethernet, OC-3, OC-12, and OC-48.
13 . The transceiver of claim 11 , wherein the second rate is lower than the first rate.
14 . The transceiver of claim 11 , further comprising:
a demultiplexer connected to the first interface; and
a multiplexer connected to the second interface.
15 . The transceiver of claim 11 , further comprising:
a framer connected to the mapper.
