DS3 LBO STRAPPING AND CONNECTIONS
The DS3 LBO compensates for the distance to the cross-connect for DS3 and wayside DS1
outputs. See Figure 3-6 for strap locations. Refer to Table 3-2 for strapping requirements.
Figure 3-6 DS3 LBO Strapping
When using 734 or equivalent type DS3 cable, 450 feet is the maximum
length to the cross-connect. The maximum length with the LBO
strapped IN is 225 feet.
