Chapter 5 Diagnostics MX-2100/2104 Installation and Operation Manual
5-8 Diagnostic Tests
You will also find a general description of the test functions applicable to I/O
modules. Specific information on the tests available for each I/O module is
provided in the corresponding module Installation and Operation manual.
In this chapter, local means the MX-2100 unit at which the test command has been
given, i.e., it is always assumed the command has been given using the front panel
controls of, or a supervision terminal connected to, the local MX-2100.
Do not set up a local loop in a remote MX-2100 with in-band management. Doing
so could cause the main link connection to be lost.
Main Link Loops
The MX-2100 supports two types of main link loops:
• Test loops activated on the KML modules. These loops provide information on
the functioning of the KML modules. However, since the loops are performed
at the interface between the MX-2100 unit and the other system elements,
these loops also provide information on the functioning of the complete unit.
• Test loops activated on the modem serving the main link, provided the
modem supports ITU-T Rec. V.54 loops. These loops provide information on
the transmission equipment that provides the connection between the two
MX-2100 units.
The following explains the main link loops, describes the front-panel indications
that are relevant to the interpretation of the test results, and in addition provide a
recommended testing sequence that allows the identification of the general
location of a fault.
Local Main Link Loop
Always perform a local main link loop on each of the two MX-2100 units.
Local Main Link Loop - Signal Path
When a local loop is activated on a KML module, the main link transmit signal is
returned to the input of the main link receive path at a point just before the line
interface. In order to provide a keep-alive signal to the transmission equipment
serving the link while the loop is activated, the line interface also transmits the
signal to the line. The loop signal path is shown in Figure 5-1.
