Abeo LAN over G.703 Extender
2
The Black Box MXU9020 is a four port auto-sensing 10/100BASE-T Ethernet Switch with an E1
Uplink. The product can be used to extend four LAN ports across a WAN link to a remote site.
Each LAN port may be connected to a single LAN workstation or to a hub or switch
supporting multiple workstations. The exact configuration will depend upon the user’s
network design and workload characteristics.
The MXU9020 Ethernet switch can switch between local LANs connected to its four ports,
and the unit may thus reduce the need for local LAN hubs and switches. The Ethernet switch
has full wirespeed filtering so that the WAN port carries only traffic destined for the remote
WAN-linked site, and an efficient HDLC encapsulation of packets ensures maimum
throughput over the WAN link. There is internal packet buffering to smooth out bursty
traffic. MXU9020’s are used in pairs, one on either side of a WAN link.
