ASMi-54LSHDSL.bis Modem• 11.4 Mbps over 2-wire line (22.8 Mbpsover 4-wire lines) for HDLCencapsulated data.SHDSL/SHDSL.BISThe modem employs TPS-TC framing64/65o for EFM (IEEE802.3) and HDLC(G.991.2) on the SHDSL/SHDSL.bis link.ASMi-54L performs line probing accordingto G.991.2. When enabled, the DSLinterface adapts its rate to the conditionof the line (noise, loop attenuation, etc.).When disabled, traffic on the DSL line istransmitted at a fixed rate selected by theuser.ASMi-54L can operate as a CO device or aCPE device according to userconfiguration.The modem uses an Embedded OperationChannel (EOC) for controlling andmonitoring the SHDSL/SHDSL.bisrepeaters. Up to eight SHDSL/SHDSL.bisrepeaters can be installed in line toincrease the operation range of E1- andEthernet-based modems.EFM BONDINGEFM bonding on the Ethernet interfaceensures that a failure or addition of a linkdoes not drop the traffic beingtransmitted over other wires in the group.The capacity of the group does notdecrease when a new link is added at alower rate.E1E1PBXASMi-54LSHDSL.bisUp to two pairsASMi-54LPBXFast EthernetFast EthernetLANLANFigure 1.

Data SheetETHERNETASMi-54L features up to four Ethernet10/100BaseT ports with half/full-duplex,autonegotiation and flow control. Thefault propagation functionality enables theunit to shut down the Ethernet user portwhen an SHDSL line failure is detected.LANs are connected by bridging.The internal forwarding of Ethernet trafficcan be configured in two ways:• By specifying the ports (a modeidentified as unaware in accordancewith Metro Ethernet Forum (MEF)standards). In this mode, all theEthernet traffic reaching one of theports is forwarded to the other port,and vice versa• By using VLANs for classification:(a mode identified as aware inaccordance with Metro Ethernet Forum(MEF) standards). In this mode,Ethernet traffic reaching one of theports is forwarded to another port inaccordance with its VLAN identifierTRAFFIC MANAGEMENT /QOSThe 802.1D, DSCP, and Per Port priorityschemes allow users to define differentQoS levels according to applicationrequirements.The modem implements the IEEE's 802.1qstandards to provide VLAN-tagging withfour levels of prioritization, enablingcarriers to offer differentiated Ethernetservices. VLAN tagging can also beemployed to separate traffic, ensuringtransparency of the customer traffic andbolstering security of management traffic.The user can activate or deactivate thepriority mechanism, and each priority(VLAN priority, DSCP or per port) can beconfigured and mapped to one of fourpriority queues.Ingress data rate can be limited on eachEthernet port.LANLANLANASMi-54L2W15 MbpsASMi-54LLANLANLANLANLANFigure 2.

ASMi-54LSHDSL.bis ModemTRAFFIC MANAGEMENT AND SECURITYThe ASMi-54L unit can be managed usingthe following connections:• Local RS-232 terminal• Telnet server, SNMP (Ver.1)• Web server• Inband management with or withoutdedicated VLAN.RESILIENCYDying Gasp condition occurs if there is aninterruption in the ASMi-54L powersource. ASMi-54L reports power failuresto the specified network managementstations by sending an SNMP trap. Thishelps a service provider identify andisolate the end-point device thatexperienced a power failure.PHYSICALThe modem is encased in a compacthalf-19” plastic enclosure that can bemounted alone or in pairs in a 19-inchrack using RAD’s optional rack mount kits(see Ordering). The modem is available inextended temperature versions (by specialrequest).OAMASMi-54L complies with the IEEE 802.3ah(IEEE 802.3-2005) standard for Operation,Administration, and Maintenance (OAM),originally developed for Ethernet in theFirst Mile (EFM) applications. OAM is a setof functions designed to monitor networkoperation on an SHDSL line, in order todetect line faults and measureperformance.LANLANLANASMi-54LPFH-42W / 4W15 / 30 MbpsS-RPTASMi-54LLANLANLANLANLANFigure 3.
