6.3Timing source

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.

6.4Line settings

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.

6.5Port settings

Adapter unit types are automatically recognised by DNT2Mi and can be seen from the Identifications menu, for instance.
