Cellular Backhaul Over IP / Ethernet

IP data service providers are strategically focused on the cellular backhaul business as they have a cost basis that is a fraction of a leased T1/E1 circuit. Cell site access to aggressively priced IP services delivered via xDSL, Optical Ethernet, HFC Cable Modem, Wireless Ethernet, and PLC Power Line Ethernet is becoming ubiquitous. 

The Engage IP•Tube products enable Cellular providers to leverage ubiquitous, economical, and reliable IP/Ethernet services as an alternative to T1/E1 circuits. The IP•Tube T1/E1 encapsulates the Base Station's T1/E1 traffic into IP/Ethernet packets for interconnection to the Base Station Controller. Full and Fractional T1/E1 connections are supported. The size and frequency of the IP packets are user configurable. Data rates from 64 Kpbs to 2.048 Mbps are supported.

The Engage Communication IP•Tube is used to provide transparent interconnection of the base stations (BTSs), base station controllers (BSCs) and mobile switching centers (MSCs) over IP Ethernet packet-switched networks. The IP•Tube T1/E1 maintains all the features of the cellular network BSC to BTS interconnections. Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit TDM lease lines.

TheIP•Tube has duplicate packet transmission and reception
features that provide for resilient performance even through a lossy interconnect. The existing deployed investments in mobile switching technologies are retained while less expensive access technologies maximize the Return on Investment for the cellular provider.

The IP•Tube's transparent operation maintains the proprietary signaling required to support cellular voice communications. Voice quality is not compromised. The IP•Tube T1 is available with one to four T1/E1 interfaces and with one to two 10/100 BaseT Ethernet interface(s). The T1/E1 interfaces have configurations that provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The protocols supported are IPTube and CESoIP.

The IP•Tube•C adds the power of lossless data compression. This optional functionality continuously detects idle/redundant data within each DS0 resulting in as much as a 56 to 1 bandwidth savings. TDM over IP bandwidth is not consumed by silent or redundant circuits. TheIP•Tube•C lossless data compression option is ideal for environments where network bandwidth is limited such as point-to-point and point-to-multi point wireless, HFC cable modems, xDSL, Power Line Ethernet or the Internet.
