PHAST-12P Terminals

The PHAST?-12P is a highly integrated SONET/SDH overhead termination device designed for ATM or PPP packet applications which can terminate a single STM-4/OC-12 line or four STM-1/OC-3 lines. Clock synthesis and clock recovery for these lines are incorporated. The device provides regeneration/section and multiplexer/line overhead processing, high order (VC-3/VC-4/VC-4Xc/STS-1/STS-3c/STS-6c/STS-9c/STS-12c) pointer tracking and retiming, and SPE path overhead processing and performance monitoring. It is a powerful solution for OC-12 and multi-OC-3 data applications, especially those requiring critical complex protection capability. PHAST-12P also provides a full 36 x 36 non-blocking STS-1 level cross connect, allowing line/path (UPSR/SNCP) protection. An APS line port may be utilized for applications such as MSP 1+1, 1:1, and 1:n architectures. The PHAST-12P is designed to interface directly with the ASPEN Express Packet/ATM switching device for data access applications. The software driver contains independent modules that allow the user to compile only relevant required components, a considerable resource savings. The function of the API's driver is to configure, control and manage the PHAST-12P device as well as collect and deliver fault and performance monitoring data to the host.ApplicationsDSLAMSMulti-Service Access PlatformsLinear MS/Line Protection ApplicationsATM and Packet SwitchesEdge RoutersRemote Access Equipment
