EXFO FTBx-88260 - Signaling Bits

Test Functions
756 FTBx-88000 Series
Signaling Bits
Signaling Bits
Allows generation and monitoring of the signaling bits. Only available for
DSn/PDH BERT framed test with DS0/E0 enabled.
From the Test menu, tap Functions and the Signaling Bits tab.
Note: Two signaling bits (AB) are available for SF or SLC-96 framing while four
signaling bits (ABCD) are available for ESF.
TX Signaling
Note: Only available when TX Signaling is enabled (refer to TX Signaling check
box when selected (cleared by default) allows generation of the
signaling bits for either the 24 - DS0 channels or 30 - E0 channels
(PCM-30 and PCM30 CRC-4). Only available when the DS0/E0 check
box is selected. on page 411). For E0 the TX signaling always displays the
ABCD bits.
 Signaling Mode, available with DS0, is configurable to 2/4/16 States
for ESF or 2/4 States for SF/ SLC-96; default is 4 States.
