FibeAir 640P

High-Capacity Wireless PDH/Ethernet Solutions

To provide TDM capabilities, next generation IP or both combined, cellular operators require a scalable and cost effective wireless transmission solution. FibeAir 640P high capacity PDH radio was designed to answer 2G and 3G deployment challenges with flexible “pay-as-you-grow” connectivity for wireless access networks. With the seamless capability of upgrading from medium to high capacity, and its built-in Fast Ethernet port, FibeAir 640P is ideal for migration from 2G to 3G cellular networks and beyond.

The FibeAir 640P is a carrier class solution that operates in the 6-38 GHz frequency range. This point-to-point system uniquely incorporates multiple TDM capacities from 32 to 64 E1s and from 28 to 64 T1s together with intelligent Fast Ethernet networking.

Delivering highly resilient native PDH transmission, FibeAir 640P is ideally suited for Base Station synchronization. With extremely low-latency and wirespeed native Fast Ethernet, FibeAir 640P meets emerging IP networking requirements, making it the perfect choice for cellular, fixed and broadband applications.

Your Choice for High Capacity PDH Transmission

TDM Voice Transmission
 with a 64 E1/T1 port chassis and capacity upgrades using software keys.

True native PDH Transmission with no circuit emulation and encapsulation! TDM traffic is transmitted separately, ensuring quality, service continuity and system synchronization.

Dynamic bandwidth allocation only enabled E1/T1 ports are allocated with capacity, while the remaining capacity is dynamically allocated to the Fast Ethernet port to ensure maximum Ethernet bandwidth utilization.

Unique Ethernet Networking Features Wire-speed Fast Ethernet - Up to 100 Mbps full-duplex throughput with capacity upgrades using software-licensed keys, from 45 to 100 Mbps.

Low Latency - Typical 0.2 msec. for 100 Mbps.

Fast Recovery Time to Support RSTP when combined with a switch/router that supports RSTP (Rapid Spanning Tree Protocol), enabling fast recovery time.

Highest Priority Level for BPDU Packets supports optimal operation of spanning tree protocols.

Built-in QOS - Provides priority support allowing QOS different classes of service, according to VLAN priority (802.1p) and DiffServ / IPv4 TOS or IPv6 TC bit values. All use 4 levels
of prioritization with user-selectable options between strict priority queuing or weighted fair queuing, with 8:4:2:1 strict weights.

FibeAir 640P in Cellular Networks

The introduction of 3G cellular networks and the huge increase in Node-B data traffic has resulted in a high demand for transmission of data-related E1/T1s from Node-Bs and BTS (Base Transceiver Station) sites to the RNC/BSC layer. In many networks, the need to carry this traffic, securely, resiliently and effectively, has led to the creation of an intermediate transmission layer in the RAN. Being further away from the core network and fiber optic coverage, on one hand, and with uncertainties of 2G/3G co-existence and traffic demands on the other, the intermediate layer must have many, and sometimes contradicting characteristics.

FibeAir 640P answers these requirements. As an optimized network element with mid to high capacity, it was designed with the intermediate layer dilemma in mind. FibeAir offers a straightforward migration path, from mid-capacity PDH links of 32/28 E1s/T1s to high capacity links of 48 and 64 E1/T1s. In addition, FibeAir provides the cellular operator with Fast Ethernet connectivity. For optimized traffic flow when both Ethernet and TDM traffic are converged, FibeAir governs the traffic using dynamic bandwidth allocation.

FibeAir 640P provides the network planner with the most flexible and efficient solution for 2G and 3G deployment challenges. Its dynamic mixing of TDM and packet traffic, and its clear migration paths from mid-capacity PDH/Ethernet to high-capacity PDH/Ethernet, and to SONET/SDH asymmetrical network access, make it the best choice for cellular network building.

FibeAir 640P High Capacity PDH Trunk

With a variety of "SDH-like" networking and management features, and simple and economic deployment and operation, FibeAir 640P is the best comprehensive choice for a PDH radio. To meet operator needs for mid to high capacity PDH trunks, FibeAir 640P offers split-mount and all-indoor installations, and software upgrades beginning with 28 T1s/32 E1s, and up to 64 E1s/T1s.

The typical FibeAir 640P PDH trunk application consists of a chained point-to-point wireless link, which carries E1/T1 traffic and bridges the capacity gap between PDH and SDH networks. The FibeAir 640P design allows operators to upgrade their links without costly additional investments in equipment. Its dynamic operation ensures that available bandwidth matches the actual demand.

The same FibeAir 640P hardware supports a Fast Ethernet port with flexible bandwidth allocation between TDM and Ethernet traffic.

FibeAir 640P is a highly resilient carrier-grade radio due to its 1+1 HSB (Hot Standby) protection capability for radio and all traffic-affecting circuitry. The protection configuration also provides an economic advantage as it significantly reduces maintenance and operation costs.
