OnSite 3088A overview
The Patton Electronics Model 3088A G.SHDSL OnSite provides high speed 2-wire connectivity to ISPs,
PTTs, and enterprise environments using Symmetrical High-data-rate Digital Subscriber Line
(G.SHDSL) technology.
As a symmetric DSL CPE, OnSite DSL offers the same data rates in both directions over a single pair of regular
twisted pair lines using TC-PAM modulation. Line connection is made with an RJ-45 jack. Standard versions
of Model 3088A are powered by an 100/230 VAC (Universal) supply. The CPE features externally-accessible
DIP switches, loopback diagnostics, SNMP/HTTP remote-management capabilities using OnSite Plug ‘n’
Play, as well as in-band management.
