The PM5329 ARROW-24xFE is a 2.5 Gbit/sec capacity Ethernet over SONET/SDH mapping device supporting both low order (VT1.5/VC-12) and high order (STS-1, STS-3c/VC-4) virtual concatenation with hitless bandwidth adjustments using fully integrated LCAS processing. The ARROW-24xFE enables the delivery of carrier-class Metro Ethernet services. Fine granularity bandwidth tuning with low order Virtual Concatenation (1.6-Mbit/sec VT1.5 / 2-Mbit/sec VC-12) enables delivery of customer-tailored 10/100 Ethernet services while maintaining network efficiency.
