Warning:
If the UKS interface is connected through the Western jack
(RJ45 jack, figure 3), make sure that the 6-pin spring terminal
has been attached to the Wago Cage-Clamp connector of the
UKS port (figure 4) and duly screwed on, as in such case there is
danger of touching the contacts of the UKS Wago Cage-Clamp
connector.
V2M/G.703 interface
The V2M port represents the exchange-end interface in accordance with G.703 / G.704
directive. Basically, the V2M interface wiring consists of overvoltage protection components
at the input and output, a transceiver and a framer. From physical point of view, the interface
is an RJ 45 jack.
A switch on the rear side allows to put the device into „test mode“, thus allowing the execu-
tion of tests and measurements. In normal mode of operation, this switch is in position „Op-
eration“. Detailed information on this switch is given in the chapters „Display and operating
elements“.

Note:
For the V2M- (E1, G.703) and T3an subscriber lines, only screened CAT5-
patch cable shall be used.
T3an interface (clock input)
The symmetrically designed interface is galvanically isolated from the circuitry. During
faultless operation, this interface provides the clock pulse that has been derived from the
received signal UKSan. The clock pulse is made of a 2.048 kHz signal with a duty cycle 1:1.
