System Configuration and Operation
Figure 5-58 shows a diagram of the test process. When Tx ABCD for w2-1 is set to mon, the
w2-1 column reflects the ABCD bits being sent out on w2-1. This pattern should be identical
to Rx ABCD on w2-2, unless the conversion table is used. When Tx ABCD for w2-1 is
optioned to set, users supplies a bit pattern of four 1s and 0s for the new ABCD bits. The Rx
ABCD stream from w2-2 is broken at circle #1, and the new pattern is inserted into the Tx
ABCD stream. The same applies for mon and set for w2-2. The bitstream will be broken at
circle 2.
PATTERN
The Pattern parameter allows you to choose a test pattern to be transmitted as PCM data on
the selected side of the circuit. The options are off, all 0 (zero), all 1 (one), m_oos (multiplexer
out of synchronization), 1:1 (a 1 followed by a zero and then another 1), 1:7 (a zero followed
by a 1 and seven zeros, then another 1), lpbk (loopback), 300 Hz (300 Hz tone), 1KHz (1 kHz
tone) and 3KHz (3 kHz tone). Since Tx ABCD only changes signaling bits, this option allows
you to choose the test pattern. You can send a different pattern toward either side of the circuit.
Mon Tx ABCD
The Monitor Transmit ABCD bit information field shows the ABCD bit pattern being
transmitted on the outbound circuit. You can change it by using the set command. This
parameter is for information only.
Mon Rx ABCD
The Monitor Receive ABCD bit information field allows you to observe the bit pattern being
received on the inbound circuit. This parameter is for information only; you cannot change it.
