Before connecting DNT2Mi to a network, you need to know how the network is
timed.
DNT2Mi can receive timing information through the line and port interfaces.
DNT2Mi can also be used as a network timing source using the unit's internal
timing circuits.
More information can be found in Sections 9.3.3 and 9.3.5.
You have to check the following items:
Line interface (Q1: 6,3,3)
The line interface settings determine line SHDSL mode, connection speed, and
use of wires.
Typically, DNT2Mi is configured as STU-R, Rate Adaptive. The Rate Adaptive
mode automatically adapts the requested fixed line rate to STU-C.
Power backoff (Q1: 6,3,6)
Select this option to enable or disable transmit power reduction on short loops.
Line alarms (Q1: 6,3,8 and 6,3,9)
The BER alarm limit and alarm severity have to be checked.
Adapter unit types are automatically recognised by DNT2Mi and can be seen
from the Identifications menu, for instance.
