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 input
pins. The Transmitting Terminal Equipment transmits
clock and data into the XRT73LC04A via the TPData,
TNData and TxClk input pins. This data is processed
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 Decoder
block. After this post-Loop-Back data has been pro-
cessed 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).
