…A key requirement for supporting TDMoP is the Interworking Function (IWF). In Figure 2, the IWF occurs at the Carrier Ethernet Switch/Router (CESR). The CESR aggregates both native Ethernet and TDM services from the access network. The IWF is required to packetize the TDM connection on the near end… -
