GR-2837
Specification developed by Telcordia (formerly Bell Labs) that defines how to use ATM virtual paths in SONET rings. It specifies a way for service providers to fill SONET pipes with traffic on an as-needed basis rather than having to provision TDM's set 64K bit/sec rates.
The GR-2837 standard provides a platform for developing multiservice transport systems based on ATM. The systems allow carriers to offer more high-bandwidth data services over their existing fiber-optic access and interoffice networks. Using GR-2837, equipment vendors can map ATM cells into SONET for maximum bandwidth utilization.
The standard describes several ways of structuring the SONET interface, including an approach that mixes SONET and ATM STS-1 pipes on the same high-speed interface, and an approach that mixes, or concatenates, the full bandwidth of the SONET facility into a single ATM pipe.
