The wireless application, shown in Figure 11, may either be in the form of WiMAX for broadband access or Wi-Fi for
smaller-scale Loans. Both technologies carry Ethernet over radio links between sites or pieces of equipment.
An application for CESoP technology over a WiMAX network is to enable the service provider to sell T1/E1 service
in addition to video and data services that are natively carried across the WiMAX connection. A ZL5011x is used at
the customer premise to packetize the T1/E1, fractional T1/E1 or TDM circuit into Ethernet packets, which are
transported back to the Central Office (CO). At the CO the TDM circuit is re-assembled from the Ethernet packets
and send to the PSTN. The CESoP traffic is converged onto the same WiMAX connection as the native Ethernet
traffic for video and data.
An application for CESoP technology over a Wi-Fi network is to enable a distributed PBX system in either a single
building or between buildings in a campus environment. In this application the T1/E1 connection from a PBX is
connected using a CESoP to another PBX. A wireless site-to-site CESoP connection between buildings in a
campus would allow for deployment savings against having to run dedicated copper cables between buildings.
