(FREEZE> key, the screen is not updated anymore and the number of the last line displayed on
screen is shown above the <F3> key; also, the total number of log lines is displayed above the <F4>
key. Using the ← and → keys it is possible to go, respectively, to the start or to the end of the log.
The ↓ and ↑ keys respectively display the next or previous line. For the screen to be updated again,
press <F1> UPDATE.
5.3 - TX/RX FRAMED mode
In this mode, the TSW200E1 can substitute a network terminal equipment or it can even
simulate a network. The TSW200E1 generates an internally framed signal at 2048 Kbps according
to ITU-T Rec. G.704, where the transmitter is independent of the receiver. This signal can have a
frame structure, which varies for PCM30, PCM30C, PCM31 and PCM31C.
When the test is started, a structured signal is generated, according to the selected pattern. In
the empty timeslots, one programmable code (idle code) is inserted. The source of the transmit
clock can be internal, external or regenerated from reception.
The the NFAS and NMFAS words and the ABCD bits of timeslot 16 can be programmed.
If it is desired to listen to the timeslot audio output by the loudspeaker during the test, press
<F4>(AUDIO) on the OK/MENU screen. To turn the loudspeaker off, press the AUDIO key again.
Use the volume buttons to adequate sound level, for it can vary a lot according to the chosen
sequence.
5.3.1 - TX/RX FRAMED Mode Configuration
The TX/RX FRAMED mode has many configuration parameters, which must be carefully
selected for the test to run correctly. Now the TX/RX FRAMED Mode setup screens are presented
with a description of the parameters of each screen. To scroll between the setup screens use the
<F4> (NEXT) OR <F1> (BACK) keys. To change a parameter, place the cursor at the desired line
using the ↑ or ↓ keys and proceed as specified at each description.

PCM : Selects a frame structure. The possible structures are PCM30, PCM30C, PCM31,
PCM31C or AUTO. For the AUTO option, the equipment identifies the frame structure
it is receiving and automatically adjusts itself to it. To change this option, use the ← or
→ keys.
•
Pattern : Selects the pattern to be transmitted in the selected timeslot (or timeslots). The
patterns are pseudo-random, with bit length 7 (2E3-1), 15 (2E4-1), 31 (2E5-1), 63 (2E6-
1), 127(2E7-1), 127 LA, 127 LD, 511 (2E9-1), 1023 (2E10-1), 2047 (2E11-1), 2E15-1,
