Installing PG-Flex System Hardware

Line Unit Compatibility
PG-Flex system configurations are based on equipment currently in production. As a rule, channel
cards, including those no longer in production, can be mixed with 4-Channel POTS and 8-Channel
POTS to provide Loop Start POTS service. (Refer to Table 3.)
When working with a mixed line unit system composition, the system performs correctly when the
line unit list numbers are correctly matched. (Refer to Table 4 on page 21 through Table 8 on
page 24 to determine which COT and RT line unit combinations work together.)
When a single Craft port interface per shelf is desired, there are two options; the FPI-729 and the
FAU-728 List 2. The FPI-729 is used where PGTC functions are required, and the FAU-728 List
2 is used where PGTC functions are not needed.
