Upon receipt of the equipment: Unpack each container and visually inspect it for signs of damage. If the equipment has been damaged in transit, immediately report the extent of damage to the transportation company and to ADC. Order replacement equipment if necessary.
SCP-FCS717-042-03H Installation and Test Mounting The FCS-717 List 4B COT shelf mounts in a standard 19- or 23-inch CO equipment bay. Use universal mounting brackets when installing the FCS-717 List 4B COT shelf onto a 19-inch frame or remove the two mounting brackets and reverse them to mount into a 23-inch frame.
Installation and Test SCP-FCS717-042-03H Connect the Frame Ground CO battery return (RTN_A, RTN_B) is separate from frame ground in the PG-Flex equipment. CKT GND and CO battery return are connected inside the PG-Flex line unit but are not connected on the backplane. Follow the instructions below and refer to Figure 4 to connect the frame ground.
SCP-FCS717-042-03H Installation and Test Connect the CO Battery The FCS-717 List 4B COT shelf can be powered from a single battery feed or from a split battery feed. Use 12 AWG or larger wire (or multiple wires of a smaller gauge) to ensure good power connections to the PG-Flex system.
Installation and Test SCP-FCS717-042-03H Split Battery Feed. For a split battery feed do the following (see Figure When using a split battery feed, -48V_A provides the battery feed for system 1 and 2, and -48V_B provides the battery feed for system 3. Remove and discard the jumper between TB1 and TB2.
SCP-FCS717-042-03H Installation and Test HDSL Pairs Connect the HDSL pairs as shown in Figure 7. Note that n is 1 for System 1, 2 for System 2, and 3 for System 3. Refer to Table 12 on page 16 for HDSL terminations and functions. Connect the HDSL Pair #1 onto wire-wrap pins HDSL_n_T1 (Tip) and HDSL_n_R1 (Ring) on the COT shelf for system n.
Installation and Test SCP-FCS717-042-03H Table 12. HDSL, Test, and Miscellaneous Connectors System* Connector Type Function System n HDSL_n_T1 .045 in. Tip and Ring terminations for HDSL Pair #1 of System n to Remote HDSL_n_R1 Wire-wrap Terminal n. The HDSL termination point for each system is: P5 for system 1, P6 for system 2, and P7 for system 3.
SCP-FCS717-042-03H Installation and Test Table 12. HDSL, Test, and Miscellaneous Connectors * Where n is 1 for System 1, 2 for System 2, and 3 for System 3. † Connecting the inhibit pins of multiple PG-Flex systems that are sharing the same bypass pair prevents other systems from attempting to use the bypass pair when it is currently being used by another system.
Page 28
Installation and Test SCP-FCS717-042-03H Connect the INHIBIT line from one COT shelf in the system to the next COT shelf sharing the metallic bypass pair when the bypass pair is shared between multiple systems in multiple shelves. Repeat Step 2 Step 3 for each PG-Flex system in the cascade.
SCP-FCS717-042-03H Installation and Test Composite Clock When required for digital services, connect the composite clock as shown in Figure 9 (refer to Table 12 composite clock terminations and functions). You can cascade the composite clock to other PG-Flex shelves. When cascading the composite clock to other PG-Flex shelves, terminate only on the last shelf in the cascade. If the composite clock is connected, it must be terminated by connecting a jumper from CC1_TIP to CC1_TERM wire-wrap pins, and from CC2_TIP to CC2_TERM wire-wrap pins on the last shelf in the cascade.
Installation and Test SCP-FCS717-042-03H Alarms If external audible and visual alarm indications are required, connect the audible and visual alarm leads from the CO alarm panel to the FCS-717 List 4B COT shelf alarm contacts (P22, see Figure 9 on page 19) according to local practice.

Installation and Test SCP-FCS717-042-03H Auxiliary Power Pairs When a PG-Flex system is used with a doubler, wire the auxiliary power pairs to the COT shelf (Figure 11) as follows: Wire-wrap auxiliary power pair 1 to PWR_1_T1 (Tip) and PWR_1_R1 (Ring) for system 1. Wire-wrap auxiliary power pair 2 to PWR_2_T2 (Tip) and PWR_2_R2 (Ring) for system 2.
SCP-FCS717-042-03H Installation and Test Cabling Verification The following verifications should be done before any cards are inserted into the FCS-717 List 4B COT shelf. Verify that there is a minimum of -42 Vdc and a maximum of -56 Vdc between the TB1 (-48V_A) and TB4 (RTN_A) screw terminals on the COT shelf.
