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. The HDSL termination point for each system is: P5 for
system 1, P6 for system 2, P7 for system 3, and P8 for system 4.
-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. . The HDSL termination point for each system is: P5 for
system 1, P6 for system 2, P7 for system 3, and P8 for system 4.
+130 Vdc is simplexed on this line for powering the Remote Terminal.
System n
PWR_OUT T1
PWR_OUT 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_OUT T2
PWR_OUT 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 for the metallic bypass pair into COT System n from
RT n. The termination point for each system is: P13 for system 1, P14
for system 2, P15 for system 3, P16, for system 4. Do not connect
metallic bypass pairs between PG-Flex systems or between other
DLC systems.
System n
TEST_n_T IN
TEST_n_R IN
.045 in.
Wire-wrap
Test connection looking into the CO switch for the selected subscriber
for System n. This connection must be set up through the PG-Flex
RS-232 maintenance port. The termination point for each system is:
P17 for system 1, P18 for system 2, P19 for system 3, and P20 for
system 4.
System n
TEST_n_T OUT
TEST_n_R OUT
.045 in.
Wire-wrap
Test connection looking into the COT channel unit of 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. The termination point
for each system is: P17 for system 1, P18 for system 2, P19 for system
3, and P20 for system 4.
CC1_TIP
CC1_RING
CC1_TERM
.045 in.
Wire-wrap
Composite Clock #1 used for primary synchronization to CO timing.
These pins (P21) can be cascaded. Terminate on the CC1_TERM pins
on the last shelf in the cascade.
CC2_TIP
CC2_RING
CC2_TERM
.045 in.
Wire-wrap
Composite Clock #2 used for secondary synchronization to CO timing.
These pins (P27) can be cascaded. Terminate on the CC2_TERM pins
on the last shelf in the cascade.
FRAME_GND
CKT_GND
.045 in.
Wire-wrap
Frame ground is isolated from CO battery ground in
PG-Flex.
EXT_ACO
CKT_GND
.045 in.
Wire-wrap
External Alarm Cutoff (P23, pins 1 and 2). A momentary connection
between EXT_ACO and circuit ground will silence the PG-Flex
audible alarms.
INHIBIT
.045 in.
Wire-wrap
PGTC Inhibit connection pin should not be connected to any other
Inhibit pins in PG-Flex or other DLC systems.
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, 2 on System 2, 3 on System 3, and 4 on System 4.
