OnAccess 1224S is a configurable 24+2G smart layer 2 Optical Ethernet
Switch, which 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. OnAccess
1224S manual-driven configuration console allows administrators to
easily setup the switch using a standard RS-232 port.

Features and specifications:
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 full wire speed
2) A range of configurable copper and fiber modules to meet the
requirements of various applications, such as FTTH, optical LAN,
Ethernet based DCS and security surveillance systems, etc.
3) 14K / 10K / 8K / 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) 802.3x flow control for a full-duplex mode and collision-based
backpressure for a half-duplex mode
7) Port-based VLAN and 802.1Q tag-based VLAN with 255 VLAN groups
8) Head of line (HOL) blocking prevention
9) By-port Egress/Ingress bandwidth management control
10) Broadcast storm filtering
11) Network management: out of band RS-232 console
12) Network protocol and standard IEEE: 802.3, 802.3u, 802.3z, 802.3ab,
802.1p, 802.1q, 802.1v, 802.1ad, 802.3x
13) Port configuration:
a) Gigabit port options:
i) Two 10/100/1000Base-TX RJ45 ports
ii) Two optional SFP 1000Base-X LC ports
b) 100Mbps ports: Up to 24 ports with 3 configurable modules in
combination with one or two groups of 4 10/100Base-TX
