OnAccess1224 family high-performance layer 2 configurable and modularized optical Ethernet switch provides an ideal solution for fiber-to-the-home (FTTH) and fiber-to-the-desk (FTTD), and for the applications where the environmental conditions exceed the reach of CAT5 copper cable. The OnAccess1224 family offers up to 24 configurable and modularized 100Base-FX or 10 / 100Base-TX ports, and two 10 / 100 / 1000Base-TX or optional SFP 1000Base-X ports for flexibility and fast connection speeds. The standard design with a 19-inch rack-mount width and a 1U height gives the highest port density of optical Ethernet switches on the market. OnAccess1224 family provides optional network management solutions that allow administrators to easily configure features, monitor performance, and troubleshoot the switches using a standard web browser and Simple Network Management Protocol (SNMP)-based network management platforms or using RS-232 console. OnAccess1224 family includes 4 models as below: 1) OnAccess1224M: manageable 24+2G optical Ethernet switch with 24 100Base-FX or 10/100Base-TX ports, and two 10 / 100 / 1000Base-TX or optional SFP 1000Base-X ports 2) OnAccess1024M: manageable 24 100Base-FX or 10 / 100Base-TX ports optical Ethernet switch 3) OnAccess1224S: smart 24+2G optical Ethernet switch with 24 100Base-FX or 10 / 100Base-TX ports, and two 10/100/1000Base-TX or optional SFP 1000Base-X ports 4) OnAccess1024S: smart 24 100Base-FX or 10/100Base-TX ports optical Ethernet switch For more detailed information please browse our homepage OnAccess1224M main features: 1) Non-blocking store-and-forward shared-memory architecture with an 8.8Gbps switching capacity and an efficient self-learning and address recognition mechanism enables the forwarding rate to proceed at a full wire speed 2) A range of configurable copper and fiber modules to meet the requirement of various applications, such as FTTx, optical LAN, Ethernet based DCS and security surveillant system 3) 6K address table for auto-learned unicast or static unicast / multicast addresses 4) 7 trunk groups of up to 4 member ports within 26 ports with flexible load distribution control and fail-over function 5) Static priority and 802.1p Class of Service with 2-level priority 6) 802.1d multiple spanning trees 7) 802.3x flow control for a full-duplex mode and collision-based backpressure for a half-duplex mode 8) Port-based VLAN and 802.1Q tag-based VLAN with 255 VLAN groups 9) Head of Line (HOL) blocking prevention 10) Static MAC addressing and filtering 11) Port mirroring 12) Source-port-based, destination-port-based, and source-destination-pair-based Sniffer functions 13) By-port Egress / Ingress bandwidth management control 14) IP Multicasting with IGMP snooping and an IP multicast table of 256 entries 15) Broadcast storm filtering Network management: 1) In band: SNMP, web-based HTTP and telnet 2) Out of band: RS-232 console
