Abstract
A method and apparatus for managing latency includes receiving data from synchronous transport signals (STS) and virtual tributary (VT) sources, providing a provisioning bit for each output associated with a memory, and adjusting a pointer for the VT sources based on the provisioning bit such that the STS and VT outputs are synchronized.
Claims21
A method for managing latency comprising:
- receiving data from high-order synchronous transport module (STM) and synchronous transport signal (STS) sources and low-order tributary unit (TU) and virtual tributary (VT) sources;
- providing a provisioning bit for each output;
- and
- synchronizing high-order and low-order outputs by adjusting a pointer for the low-order sources based on the provisioning bit.

A computer program product tangible embodied on a computer readable medium, for provisioning cross-connects in network switching environment comprising instructions for causing a computer to:
- receive data from high-order synchronous transport module (STM) and synchronous transport signal (STS) sources and low-order tributary unit (TU) and virtual tributary (VT) sources;
- store the data received in a memory for subsequent output;
- provide a provisioning bit for each output;
- and
- synchronize low-order and high-order outputs by adjusting a pointer for the low-order sources based on the provisioning bit.

An apparatus including:
- a first circuit configured to receive data from high-order synchronous transport module (STM) and synchronous transport signal (STS) sources and low-order tributary unit (TU) and virtual tributary (VT) sources;
- a memory for storing the data received for subsequent output;
- a connection memory for storing a provisioning bit for each output;
- a second circuit configured to synchronize the low-order and high order outputs by adjusting a pointer for the low-order sources based on the provisioning bit.
