When connecting through DSL, certain switches on the field terminal board
need to be aligned, as seen in  Chapter 6.1.2 - SW2 and SW3 (p.21). With
the switches on the DSL modem itself, it is possible to fine-tune the quality of
the communication.  Please see Chapter 7 - Optional DSL Modem (p.22).
5.1.1 Connector TB2
Table 3 shows an overview of the connections on TB2. Maximum cable core
is 1.5 mm².
When connecting the communication through these connectors, the J4
connector should be left disconnected.  See Chapter 5.1.2 - Connector J4
(Ethernet RJ45 Connection) (p.16).
* Only possible with the optional DSL modem print board
** Power over Ethernet (POE) requires an external power supply, limited-energy (max. 48
Vdc max. 3 A), reinforced insulation is provided between input and output by safety
transformer and distances on PCB. Power over Ethernet complies with IEEE 802.3af
*** Cable must be UTP, STP or FTP with category 5E or 6. Maximum cable length is 100
meters.
