OmniAccess 5510 Unified Services Gateway
OmniAccess 5510 USG is designed to provide most commonly used network services such as routing,
switching, wide area network (WAN) connectivity, network security with firewall, and related services using a
non-modular platform providing Ethernet switching and a single WAN interface.
OmniAccess 5510 USG is a fanless 1U fixed chassis containing 4 10/100 Switched Ethernet ports, 1 10/100
Ethernet port, and either a T1E1 port/Universal Serial Port (USP)/ADSL Annex A or Annex B port.
OmniAccess 5510 USG Ports
ADSL Port
Asymmetric Digital Subscriber Line (ADSL) takes its name from the comparatively high bandwidth
downstream with low bandwidth upstream. It works over the same copper already installed by the telephone
companies for voice traffic and is “always on” as compared to dial up services.
The distinguishing characteristic of ADSL is that the volume of data flow is greater in one direction than the
other, that is, it is asymmetric. ADSL supports applications with "asymmetric" traffic demand such as web
surfing, file downloads, and telecommuting. Providers usually market ADSL as a service for people to connect
to the Internet in a relatively passive mode: able to use the higher speed direction for the "download" from the
Internet but not needing to run servers that would require bandwidth in the other direction. Advantage of
ADSL is that it allows users to have telephone conversations and transfer data simultaneously.
Alcatel-Lucent OmniAccess 5510 USG is available in both Annex A and Annex B flavours of ADSL. Annex
A supports ADSL over POTS (Plain Old Telephone System) and Annex B supports ADSL over ISDN
(Integrated Services Digital Network).
T1E1 Port
The T1E1 port supports American and European (International) digital transmission standards. The T1E1 port
can support data rates of 1.544 or 2 Mbps depending on the type of connectivity.
