Abstract
A system for hair pinning-time division multiplexing (TDM) calls has a gateway positioned between a non-TDM network and communication equipment coupled to the gateway via a plurality of TDM lines. The gateway has a plurality of signal processing elements configured to encapsulate the TDM call data into a plurality of packets utilizing a protocol suitable for transmission through the network, and each signal processing element has its own time domain such that the signal processing elements operate asynchronously. The gateway also has a central processing element configured to forward the packets to the network via the network protocol. The central processing element is further configured to identify packets which are mapped to channels of TDM lines coupled to the gateway and to forward the packets to the appropriate signal processing element for transmission through the appropriate TDM channel. Accordingly, hair pinning across asynchronous time domains is achieved within the gateway.
