With two doublers, four sets of auxiliary power pairs must be installed between COT and the RT. These auxiliary power pairs must be the same wire gauge (or larger) as the pairs used for HDSL and power.

Figure 3. Two Doubler HDU Installation with PG-Flex
PG-Flex systems do not support doubler loopbacks.
The PG-Flex system can operate with a number of other systems, sharing the same cable binder group, such as:
•T1 (1.544 Mbps capability)
•POTS
•DDS
•Other PG-Flex systems
With doublers, PG-Flex CO line units produce ±125V to ±130V on the HDSL and auxiliary power pairs. At least ±75V is required at the RT for ringer voltage and POTS loop current to meet specification.
Refer to the PG-Flex COT shelf, RT enclosure, and line unit practices for additional information on PG-Flex powering and auxiliary power pair requirements (see “Documentation” on page iii).
