FlexDSL ORION 2 - Compatibility of Wetting Current Supply and Remote Power Supply Modes; Remote Power Consumption for Ntus

User Manual NTU Orion 2
16
• When working with lines and the a junction box, the xDSL cable should be disconnected
from the device supplying the remote power;
• The insulation of cable pairs, junctions (junction boxes, plinths, etc.) should correspond to
norms and standards of the network;
3.3.1.2 Compatibility of wetting current supply and remote power supply modes
The table of compatibility of the wetting current supply and remote power supply modes is
presented below.
The devices operating in pairs should be configured for mutual operation (“√” –
compatible). The use of the mode «-» is not recommended because it may cause: high power
consumption, degradation of communication (communication stability), the use of additional
safety measures. The mode “incompatible” (inc) will not allow the devices to establish
communication (because in this case one or both devices will be de-energized).

3.3.1.3 Remote power consumption for NTUs
NTU devices can be configured to the local power supply and remote power supply modes
(LP/DP). The LP/DP modes are switched from one to another with the help of a toggle on the
rear panel of the device (see Figure 3.4).
