The cell site backhaul application, shown in Figure 10, consists of 2G, 2.5G and 3G base stations, co-located at a
cell site, connected to their respective 2G, 2.5G base station controllers and 3G radio network controller. The
traditional leased T1/E1 lines between the cell site and the base station controllers is now replaced by a packet
network such as fixed wireless or Gigabit Ethernet (GE) fiber, that may be owned by the carrier or accessed
through a service provider.
The ZL50110/11/12/14 would sit in a box either external to the base stations, or integrated in them, and would
transparently carry multiple T1/E1s to the Base Station controllers/Radio Network controllers using CESoP
connections. At the base station controller location another ZL50110/11/12/14 would terminate the CESoP
connection and provide the T1/E1 line to the controllers.
The use of the ZL50110/11/12/14 would allow for lower cost transport between the two locations, due to the
replacement of the leased T1/E1 line cost. The CESoP connection would allow the T1/E1 to meet the strict timing
requirements for 3G base stations. Each T1/E1 may be asynchronous should a service provider be backhauling
T1/E1s from multiple carriers.
