7=SAME AS LOOP
If the DSU III ARdc is set for a loop rate of 64 kbps and SAME AS LOOP is
selected, then SCRAMBLER ON/OFF options are available (as shown in
Figure 6-1). The factory default setting is SCRAMBLER OFF.
Table 6-2 shows the equivalent AT commands for setting SCRAMBLER
ON/OFF for 64 kbps loop rates.

1=SCRAMBLER OFF

3=SUPPRESS LBE
For 64 kbps clear channel operation, there is a possibility that the DTE data
sequences might mimic network loop maintenance functions and erroneously
cause other network elements to activate loopbacks. To prevent this, the SCRAM-
BLER ON or SUPPRESS LBE option should be selected for both the local and
remote DSU III ARdc.
For loop rates of 2.4, 9.6, 19.2, and 38.4 kbps the DTE rates shown in Fig-
ure 6-2 are available.
