TM A CONEXANT BUSINESS MindControllerTM OC-12 OC-12 ATM Policer M27650 M27650 OC-12 OC-12 ATM Policer The M27650 M27650 provides ATM layer Usage Parameter Control (UPC), Operations, Administration, and Maintenance (OAM) processing, header translation, and statistics at OC-12 OC-12 rates. Up to 64K connections are supported. The M27650 M27650 is part of the MindControllerTM family of Application Specific Network Processors (ASNPs) that provide flexible, easy to upgrade network solutions at competitive prices. Usage Parameter Control (UPC) > K E Y F E AT U R E S > OC-12 OC-12 throughput > ATM Forum TM 4.0-compliant UPC, with optional Partial Packet Discard on AAL5 channels > UPC rates configurable from one cell per second to line rate, with accuracy to within one percent > ATM cell header translation > I.610-compliant OAM (F4/F5 alarms, loopback, continuity check, activation) > Per-PHY and per-connection statistics > Supports 64K connections > Supports UTOPIA Level I/II ATM cell interfaces > Cell insertion and extraction via host The UPC function provides two generic cell rate algorithms (GCRAs) per connection, and conforms with CBR.1, VBR.1, VBR.2, VBR.3, UBR.1 and UBR.2 as defined in the ATM received at VP end points. The loopback and activation/ Forum TM 4.0 specification. Policing is enabled on a deactivation OAM cells are sent to the host for processing. per-connection basis. Connection rates from one cell per second to 100 percent of line rate are policed to Header Translation within one percent of the desired value. Partial Packet The M27650 M27650 supports the standard 53-byte UNI and NNI Discard (PPD) can be configured on AAL5 channels. cell formats. For channel-switched connections virtual channels (VCs) and VP endpoints - the VPI and VCI fields OAM Processing in the ATM cell header are replaced with new values. For The M27650 M27650 supports fault management via alarm path-switched connections (VP midpoints), only the VPI indication signal (AIS) and remote defect indication (RDI), is replaced. The PTI and CLP fields from input cells are continuity check, activation/deactivation and loopback OAM copied and modified as appropriate. functions for both path (F4) and channel (F5) levels. In addition, each connection can be individually configured as a segment end point, a connection end point, both or neither. The fault management and continuity check functions are processed internally, with appropriate status indications provided to the host. F4 to F5 escalation Statistics The M27650 M27650 provides the following statistics: aggregate cell count, total discards, CLP=0 discards, tagged cells and OAM cells. All counters are available on a per-PHY and per-channel basis. is supported for virtual path (VP) AIS alarm cells > Management Functions Via Host Applications A host processor controls the M27650 M27650. The host issues commands The M27650 M27650, when used in conjunction with the M27651 M27651 ATM via the PCI bus, and receives results back through indications. Shaper, forms a complete OC-12 OC-12 ATM-layer solution. It can also Commands are available to open, close or modify PHY ports; open, be used as a stand-alone device when only policing functions are close or modify channels; get per-PHY or per-channel statistics, required. Typical applications include ATM switches, routers, multi- and get or set OAM state. The host can also send or receive cells service edge concentrators, DSLAMs and wireless base stations. to and from any channel.
