NewTelco Systems T-Metro TM-7124S-DC ethernet switch 24port 1Gbe fiber SFP with 1 expansion slot 1DC PSU. Free shipping in the lower 48!The T-Metro 7124S multiservice aggregation deviceis a member of Telco Systems’ field-proven T-Metrofamily of Carrier Ethernet switches.The T-Metro family of products supports both CarrierEthernet and MPLS with OAM (operations, administrationand maintenance) tools and extensive QoS capabilities.This rich combination of technologies allows serviceproviders to deliver enhanced service offering whilemaintaining competitive pricing.The T-Metro provides access to advanced data servicessuch as virtual private LAN services (VPLS), virtual privatewire services (VPWS) and hierarchical virtual private LANservices (H-VPLS).Advanced Synchronization and TimingThe 7124S provides a comprehensive set ofsynchronization options optimized for cellular operatorslooking to backhaul their data and voice traffic from theNode-B\\BTS to their core network over Ethernet\\MPLStransport.The device supports Synchronous Ethernet (SyncE), IEEE1588v2, external clock source via BITS interfaces andclock distribution from one source to another for allsource types. This flexibility allows any cellular operatorto achieve a synchronization solution suitable for his ownneeds.Service Monitoring and ManagementThe 7124S service multiplexing capability enables serviceproviders to deliver multiple, isolated, services on a perportand/or a per-flow basis. Provisioning, monitoring andtroubleshooting of each individual service can be donewithout impacting other services.The 7124S supports industry-standards IEEE 802.1agConnectivity Fault Management (CFM) and ITU-T Y.1731allowing the service provider to monitor end-to-endservices, identify connectivity and performance issues andisolate the problem from a remote location without truckrolls. The 7124S provides a wide set of QoS features thatenables the service provider to have a granular controlover the behavior of traffic and services in the network..Carrier-class designTelco Systems’ Internetworking Operating System(BiNOX) provides the robust administration, management,QoS, security, and performance requirements that allowsthe service provider to successfully deploy triple-playservices, thus enhancing their competitive edge.The 7124S boasts a wide variety of resiliency protocols.It offers link-level mechanisms such as resilient link andLAG with LACP, network-wide mechanisms such as MSTP,G.8032 and FRR and service-level mechanisms such asG.8031.The 7124S offers the carrier an ideal solution, incorporatinghigh capacity in a compact size (only 1.5RU in height, 10”in depth). The 7124S supports 24 dual-speed (100/1000)Ethernet plug-in (SFP) ports and one expansion slot foradd-on line cards. The 7124S supports hot-swappable,redundant power supplies (either AC or DC) and hotswappablefan-tray.ManagementThe 7124S is fully manageable via Netconf, SNMP orCLI with either In-band (IB) or Out-of-Band (OOB)management tools. The CLI complies with the de-factoindustry standardAdministrators can use industry-standard SNMP-basednetwork management systems, or the EdgeGenie™Service Management System. It provides the networkoperator with a state-of-the-art, powerful, SNMP basedconfiguration, monitoring and maintenance platform.SpecificationsStandards and CertificationsIEEE 802.1D; IEEE 802.1Q; IEEE 802.1P; IEEE 802.1adIEEE 802.1p Priority Queuing; IEEE 802.1u-2001IEEE 802.3x PAUSE: flow control and back pressureIEEE 802.1x; IEEE 802.3adIEEE 802.1d, IEEE 802.1w, IEEE 802.1sIEEE 802.3; 802.3u; 802.3z; 802.3ab EthernetIEEE 802.3ah EFM-OAMIEEE 802.1ag CFMIEEE 1588v2 P-t-P timingITU-T G.8261/2,4 ITU-T G.781 Synchronous EthernetITU-T Y.1731ITU-T G.8031; ITU-T G.8032ANSI*: ANSI T1.102, ANSI T1.105, ANSI T1.107, ANSI T1.403,ANSI T1.404, ANSI T1.231,Bellcore*: GR-253-CORE, GR-499-CORE, GR-1244-CORE,ITU-T*: G.703, G.704, G.706, G.707, G.732, G.775, G.781,G.783, G.813, G.821, G.823, G.824, G.825, G.826, G.831InterfacesFlexible Ethernet combo-port interfaces• Fiber SFPs (100M and 1000M)• Dual-rate copper SFPs (100/1000M)• Single-rate copper SFPs (1000M)• 10G Fiber XFPs*• Sync Clock (2 x In, 1 x Out) Coaxial “1.0/2.3 R/A” interfaces*• Phase Clock (2 x In, 1 x Out) Coaxial “1.0/2.3 R/A” interfaces*Jumbo frames up to 9216 bytesASCII/RJ-45 management portsSecurity FeaturesSecure management protocols• SNMPv3, SSHv2Wirespeed Access control lists: Layer-2/3/4 and policy-enabledManagement VLANRADIUS and TACACS+ authenticationLayer 2 Features32k MAC addresses802.1p, ToS, and DiffServ classification and remarkingFull range of IEEE 802.1Q based VLANsRate-limiting for bandwidth allocationTransparent LAN ServicesIGMP SnoopingPort mirroringMPLS FeaturesH-VPLS spokesLSR functionalityRSVP-TE and OSPF-TELDPTraffic Management FeaturesQoS with ToS, and Differentiated ServicesEight system-wide traffic classes with flexible hybrid scheduling.Classification by:• Ingress interface, or port• Ingress/egress rate limiting and egress shaping• Source and/or destination MAC address• IEEE 802.1ad priority code points (PCP)• IPv4 TOS/DSCP field2 rate 3 color (CIR/EIR) rate limitingCongestion avoidance:• Tail drop• Weighted Random Early Detection (WRED)Protection FeaturesResilient LinkFast-Ring with sub 50ms switchover in fiber Ethernet ringsITU-T G.8031ITU-T G.8032Link aggregation groups, including LACP with MAC Reroute (FRR)Dual homing with active and guarded LSPsOAM FeaturesIEEE 802.3ah EFM-OAM;IEEE 802.1ag CFM;ITU-T Y.1731Embedded RFC2544 test headManagement FeaturesService management system• EdgeGenieMultiple management access protocols and tools• SNMPv1/v2c/v3; Telnet, SSHv2, TFTP, NTP• DHCP (client)• SYSLOG• NETCONF/YANGEmbedded command line interface (CLI)Direct IP-based management modeRMON Group 1, 3, 4, and 10Regulatory ComplianceSafety: NRTL certified: C-UL 60950, CSA 22.2 No.950,EN/IEC 60950, TUV/GS (EN60950),CB, EN 60825-1/2EMC: CE Mark: EN50081-1: EN55022 Class A, EN60555-2/3;North America: FCC 47 CFR Part 15 Class A; ICES-003 Issue4 Class A (Canada); Japan: VCCI Class A;Australia/NZ: CISPR 22 Class AImmunity: EN50082-1, EN/IEC 61000-4-2/3/4/6/11RoHS ComplianceGeneral SpecificationsDimensions (W x H x D):483 mm (19”) x 67 mm (2.625”) x 253 mm (10”)Weight: 5.2 kg (11.5lb)Operating Temperature: -20°C to 65°C (-4°F to 149°F)Humidity: 5% to 95% non-condensingInput power: 100-240 VAC, 50/60 Hz-36VDC to -72VDC* Using add-on line-card and future SW update, purchased separately
