MX-2100/2104 Installation and Operation Manual Chapter 5 Diagnostics
Diagnostic Tests 5-7
Activating / Deactivating Tone Injection on a Voice Channel
After tone injection is activated on a voice channel, the remote subscriber
connected to this channel should hear the test tone (an 1 kHz tone) clearly and
loudly. If downloading is enabled, you can also activate a remote loop: in this
case, the test tone is also heard by the local subscriber.
MX-2100 Diagnostic Functions, General
The MX-2100 diagnostic functions can be used to test the proper operation of the
MX-2100 system and identify efficiently the faulty components. The available
functions are:
• Connection of a local or remote test loop on the main link
• Connection of a local or remote test loop on the modem serving the main link,
provided the modem supports the ITU-T Rec. V.54 control pins
• Connection of a local or remote test loop on the desired I/O module channel
• Pseudo-random sequence (PRBS) transmission on a selected channel of a data
I/O module
• Bit error rate test (BERT) on a selected channel of a data I/O module, using a
pseudo-random sequence
• Injection of 1 kHz, 0 dBm0 (digital milliwatt) audio signal for testing the
transmit path of the desired voice I/O module channel.
Note that no tests are available for the KCL.2 module, because this module
controls the management interface, i.e., the front-panel controls and the
interfacing with a supervision terminal or an SNMP network management station,
and the MX-2100 operation. Therefore, the KCL.2 module is inherently “tested”
when a proper response is obtained to any operator request, and the MX-2100
operates normally.
If it is necessary to replace the KCL.2 module, you can preserve the existing data
base in two ways:
• The fastest way is to remove the NVRAM component from the replaced
module and installing it on the replacement module.
• If the above way is not possible, the replacement module can be preconfigured in
another MX-2100 and then installed in the desired unit. This allows the
replacement of a defective KCL.2 module without disrupting the operation of the
MX-2100, because the MX-2100 can continue to operate even if the KCL.2
module is temporarily removed.
If you insert a new KCL.2 module in an operating MX-2100 without first either
transferring the NVRAM (or preconfiguring the module), then when the KCL.2
module is inserted in the MX-2100 the system is reset to the default values.
Test control is effected from the TEST OPTIONS menu. In this chapter you will
find information on the tests (loops) available on the main link interface modules
and the main link modems.
