TSW200E1
signal got by the TSW200E1 is sent to its transmitter. The clock employed is the receive clock, as
the equipment is inserted in the middle of the circuit under test.
If it is desired to listen to the audio output of one receive timeslot during the test, it is
necessary to turn the loudspeaker on. This is done by means of the AUDIO function key. To turn off
the loudspeaker, press the AUDIO key again. In this case, to avoid the selected timeslot to be
checked by any selected test pattern, configure the PATTERN parameter for the IDLE option.
For transmission, if no timeslot is selected in the Tx Slots, the TSW200E1 transmits every
incoming signal, without caring for the selected pattern and thus remaining transparent to the
system.
The frame structured data can be replaced by a test pattern in one or more timeslots. To do
this, it is necessary to select one or more timeslots in the TX Slots. If no timeslot is selected in the
RX Slots option, the Test Set will simply replace this pattern and transmit, without analysing the
incoming data.
The Sa bits of the NFAS words and the timeslot 16 bits ABCD can be programmed,
allowing the insertion of signalling tones in the A, B and C bits.
5.4.1 - THROUGH FRAMED Mode Configuration
The Through Framed mode configuration parameters are the same as the TX/RX Framed
mode configuration parameters as described in section 5.3.1.
5.4.2 - Through Framed Test example
5.5 - MUX Mode
In this mode, the TSW200E1 is used to test multiplexers. A test pattern is sent through one
or more channels of the multiplexer, by the V.24/RS232, V.35/V.11, V.36/V.11, X.21/V.11 or RS530
interfaces. The multiplexer-generated 2 Mbps frame-structured data flow is then analysed by the
TSW200E1 G.703 - 2 Mbps interface.
5.5.1 - MUX Mode Configuration
The MUX mode configuration parameters are a little different from the TX/RX Framed
mode. It has one more parameter to select the interface to be used to send the test patterns to the
multiplexer. As it does not transmit using the G.703-2M interface, it does not have the parameters
that set up the transmission by that interface. Below the list of the MUX mode parameters follows:
•
PCM : see section 5.3.1
•
Pattern : see section 5.3.1
