Reducing the Cost of Wireless Backhauling Through Circuit Emulation

Data rate requirements of backhaul connections for wireless Base Transceiver Stations (BTSs) continue to increase, while the cost of available Gigabit Ethernet connections decreases. As a result, IP/Ethernet backhauling has become a prime choice for new installments. However, for the hundreds of thousands of base stations deployed with Time-Division Multiplexed (TDM) connections (E1/T1), carriers must pay much more for TDM lease lines, but can cut their costs by using Circuit Emulation Service (CES) to transport the signals over a less expensive Ethernet network.
