PM7325 S/UNI®-ATLAS-3200
Guaranteed Frame Rate (GFR) Policing with Minimum Cell Rate Frame Tagging.
Gbit/s ALayer Solution
FEATURES
Monolithic single chip device which handles ALayer functions direction including VPI/VCI address translation, cell appending, cell rate policing, cell counting requirements (virtual connections). more PM7325 S/UNI®-ATLAS-3200 devices cascaded support additional VC's. Instantaneous transfer rate 3200 Mbit/s supports cell transfer rate 5.68x106 cells/s. configured Ingress mode device Egress mode device. POS-PHY/UTOPIA Level Switch interface supports 32-bit interface. Extended cell format supported byte cell). Packets processed buffered passed through transparently. Handles logical ports. Supports full duplex SCI-PHYBackwards Cell Interface Port which allows Ingress mode device Egress mode device communicate behave single bi-directional device. Supports 64-bit (with without parity) External Pipelined SRAM interface. Includes FIFO buffered 32-bit microprocessor interface cell insertion extraction, deterministic Table access, status monitoring configuration device. Per-PHY output buffering scheme resolves head-of-line blocking issue. Ingress Egress functions include flexible search engines that cover entire PHYID/VPI/VCI address range, dual leaky-bucket policing, per-VC cell counts, OAM-FM OAM-PM processing.
ITU-I.610 (1999) compliant both Ingress Egress directions. Complete Fault Management (AIS, RDI, processing, VP/VC, Segment/End-to-end flows VCs. Complete Performance Monitoring processing, VP/VC, Segment/Endto-end, Forward/Backward flows, Uni-directional VCs. Per-PHY AIS/RDI generation.
CELL COUNTING
Per-VC counts include CLP0 cells, CLP1 cells, cells, cells, invalid cells, cells violating contract total AAL5 frames. Per-PHY counts include CLP0 cells, CLP1 cells, cells, errored cells, unassigned/invalid cells policing violations. Per-device counts include total cells received/transmitted, physical layer cells.
POLICING
ITU-I.371, AForum TM4.1 compliant, per-VC programmable dual leaky-bucket policing with programmable action (tag, discard, count only) each bucket, each with three programmable noncompliant cell counts. Per-PHY single leaky-bucket policing with programmable action (tag, discard, count only).
