The Field Shelf can be configured to support a combination of 4/6 channel and 24 channel systems as shown in
Figure 5 . PLL-735s and FLL-814s may be installed in any available slots and in any order in the Field Shelf.
FLL-814s must be placed in the shelf in an odd/even slot relationship – slots 1-2, 3-4, 5-6, 7-8. The same criteria for
power pairs and DS1 circuits apply for this configuration as with the FLL-814 configurations previously described.
