System n*
HDSL_n_T1
HDSL_n_R1
.045 in.
Wire-wrap
Tip and Ring terminations for HDSL Pair #1 of System n to Remote
Terminal n. -130 Vdc is simplexed on this line for powering the
Remote Terminal.
System n
HDSL_n_T2
HDSL_n_R2
.045 in.
Wire-wrap
Tip and Ring terminations for HDSL Pair #2 of System n to Remote
Terminal n. +130 Vdc is simplexed on this line for powering the
Remote Terminal.
System n
PWR_1_T1
PWR_1_R1
.045 in.
Wire-wrap
System n auxiliary Power Pair #1. Used for auxiliary power to the RT
when using a PG-Flex doubler unit.
System n
PWR_2_T2
PWR_2_R2
.045 in.
Wire-wrap
System n auxiliary Power Pair #2. Used for auxiliary power to the RT
when using a PG-Flex doubler unit.
System n
BYPASS_n_T
BYPASS_n_R
.045 in.
Wire-wrap
Termination (P10 for system 1 and P20 for system 2) for the metallic
bypass pair into COT System n from RT n.
System n
TEST_n_T_IN
TEST_n_R_IN
.045 in.
Wire-wrap
Test connection looking into the CO switch (P13 for system 1 and P14 for
system 2) for the selected subscriber for System n. This connection must
be set up through the PG-Flex RS-232 maintenance port.
System n
TEST_n_T_OUT
TEST_n_R_OUT
.045 in.
Wire-wrap
Test connection looking into the COT channel unit (P13 for system 1 and
P14 for system 2) for the selected subscriber for System n. This
connection must be set up through the PG-Flex RS-232 maintenance port.
In some applications, this pair will be jumpered to the BYPASS pair
from RT n.
CC1_TIP
CC1_RING
CC1_TERM
.045 in.
Wire-wrap
Composite Clock #1 (P18). Used for synchronization to CO timing.
When cascaded, terminate only on the last shelf in the cascade.
CC2_TIP
CC2_RING
CC2_TERM
.045 in.
Wire-wrap
Composite Clock #2 (P19). Used for synchronization to CO timing.
When cascaded, terminate only on the last shelf in the cascade.
FRAME_GND
CKT GND
.045 in.
Wire-wrap
Frame ground (G1). This is isolated from CO battery return in PG-Flex.
EXT_ACO
CKT_GND
.045 in.
Wire-wrap
External Alarm Cutoff (P16). A momentary connection between
EXT_ACO and circuit ground resets PG-Flex audible alarm relays.
BATT RTN
CKT GND
.045 in.
Wire-wrap
CO battery return (TB3). This is isolated from frame ground in PG-Flex.
SPARE
P99 are spare pins.
* Where n is 1 on System 1 and 2 on System 2.
