Hybrid Mobile Backhaul

The following application shows an example of the iConverter T1/E1 MUX/M used in a hybrid TDM/Ethernet mobile backhaul transport network.

A wireless service provider has enhanced their network to support 3G/4G services. The new equipment uses Ethernet for backhaul at the Cell Site, while their existing legacy 2G/2.5G equipment uses TDM (T1) for backhaul.

Using the iConverter T1/E1 MUX/M at the Cell Site, the service provider is able to multiplex up to 16 T1/E1 circuits and one 10/100/1000 Ethernet service on a common fiber link. The fiber carries the multiplexed traffic to a second iConverter T1/E1 MUX/M that is installed at the Base Station Controller (BSC) and Radio Network Controller (RNC). The T1/E1 MUX/M converts the legacy TDM traffic back to T1/E1 interfaces, where it is connected to the TDM network. The MUX also converts the Ethernet traffic back to a 10/100/1000 interface, where it is connected to the provider’s IP network.
