1.1 General Overview of the UniPhyer LB-UA2348 and LB-UA2324
The UniPhyer LB-UA2324 (24 port) and LB-UA2348 (48 Port) are Line Bridge Gateways within a
rack-mountable 2U high enclosure. The system provides up to 48 Line Bridge ports that when
connected to PhyAdapters can provide an IEEE 802.3af compliant 10/100 Mbps Power over Ethernet
(POE) port with broadband data rates using the two wire intra-office legacy wiring infrastructure. The
UniPhyer LB-UA2348 is capable of delivering very high speed data rates with up to ADSL2+
performance for each of the 48 ports, ideal for Voice over IP network deployments. With advanced
QoS features, the UniPhyer LB-UA2348 also has advanced Quality of Service (QoS) features to further
customize deployment to meet network needs.
The UniPhyer LB-UA2348 provides two uplink trunk ports with both electrical and optical Gigabit
Ethernet (GbE) interfaces..
The UniPhyer LB-UA2348 can act support of 802.3ad link aggression that extends the uplink
bandwidth to 2 Gbps and increases the reliability of uplink by line protection feature of 802.3ad. The
UniPhyer LB-UA2348 also supports stacking configuration that several UniPhyer LB-UA2348s can
stacked up to provide services to more subscribers for one GBE uplink.
