b. Operating in the Hardware Mode
To configure Channel (n) to operate in the Analog Lo-
cal Loop-Back Mode, set the LLB_(n) input pin (pin
76, 84, 97 or 105) “High" and the RLB_(n) input pin
(pin 77, 85, 96 or 104) "Low".
4.2
THE DIGITAL LOCAL LOOP-BACK MODE.
When a given channel is configured to operate in the
Digital Local Loop-Back Mode, the channel ignores
any signals that are input to the RTIP and RRing in-
put pins. The Transmitting Terminal Equipment trans-
mits clock and data into the XRT73L04B via the TP-
Data, TNData and TxClk input pins. This data is pro-
cessed through the Transmit Clock Duty Cycle Adjust
PLL and the HDB3/B3ZS Encoder block. At this
point, this data is looped back to the HDB3/B3ZS De-
coder block. After this post-Loop-Back data has been
processed through the HDB3/B3ZS Decoder block, it
outputs to the Near-End Receiving Terminal Equip-
ment via the RPOS, RNEG and RxClk output pins.
Figure 34 illustrates the path that the data takes when
the chip is configured to operate in the Digital Local
Loop-Back Mode.
Configure a channel to operate in the Digital Local
Loop-Back Mode by employing either one of the fol-
lowing two-steps:
a. Operating in the Host Mode
To configure Channel (n) to operate in the Digital Lo-
cal Loop-Back Mode, write a "1" into both the LLB
and RLB bit-fields within Command Register CR4-(n).
