Interfaces
The interfaces have the following functions and pin assignments:
DSL (UKS) interface (RJ 45)
The DSL (UKS) interface is responsible for matching to the SHDSL line interface. Basi-
cally, the interface wiring consists of two SHDSL transceivers with related line interfaces
and overvoltage protection components. The 2 Mbps signals, coming from the subscriber
interface (V2Man/G.703), are split up to one or two paths, processed in the SHDSL framer
as specified by ETSI, and then transmitted over one or two SHDSL transceivers on the line.
At the UKS line interface, a TC-16-PAM line code with a line digit rate of 773

kbaud (two-pair system) is used.
Transmission is effected on each path in duplex mode (bidirectionally). The echo cancella-
tion technique is applied for direction separation.
Physically seen, the interface represents an RJ 45 jack, alternatively a Wago Cage-Clamp
connector. Figure 3 shows functions and pin assignments of the interfaces:
