GENERAL 1.01 his section provides identification, installation, and connection information for the 615A panel used to mount interconnecting units (Us) Whenever this section is reissued, the reason for reissue will be listed in this paragraph he 615A panel provides connecting facilities between telephone company central office (CO) or PBX lines and customer-provided equipment (CPE) he internal panel wiring is covered in this section. Refer to the section covering the specific Voice Connecting Arrangement (VCA) for connections for the CPE and the particular U in use. 2. DENFCAON DESPON 2.01 he 615A panel (Fig. 1 and 2) consists of a cast aluminum carrier equipped with three 914A connectors in the upper row and three 913A connectors in the lower row. he 6- by 8-inch carrier has a full rear panel mounted on four standoffs making it inches deep. he vertical rack space required is 8 inches (9 inches when mounted on 99B brackets) he rear panel is provided with a plug (P1) and a 661 connecting block. he 661 connecting block provides terminations for the incoming and R leads, and leads from the 914A connectors, battery and ground, ringing supply, and for multipling power to other 615A panels. he plug provides for circuit connections to CPE. Separate fuses are provided for each connector hree 8-inch Us (101-, 102- or 120-type) or six 4-inch Us (108A) can be mounted in the 615A panel. t is not wired to accept the 75A control unit; VCAs requiring this unit must use the 604B or 604C panel. Each 8-inch U plugs into a vertical arrangement of an A connector (914A, 40 pin) over a B connector (913A, 20 pin). he 4-inch Us will plug into either connector. A P40V590 guide assembly must be mounted in the center of each vertical position to support the 4-inch Us. Fig. 3 shows the connector and trunk arrangement in the 615A panel. Fig. 4 shows the lead designations and pin numbers for these Us, and able A shows the connectors in which they are used he fuse and power distribution is shown in Fig. 5 and able B. he 615A panel is designed to be used with a 24-volt or 48-volt power supply. he latter is used only when 120-type Us arranged for 48-volt operation are installed he 24E 112-ampere fuses attach to screw terminals on the rear of the panel as shown in Fig he A and B connectors are factory-wired to the 661 connecting block and to the 50-pin KS-16671, List 1 plug (P1) on the rear of the panel. Fig. 6 shows connections to the 661 connecting block, Fig. 7 shows the connections to the A and B connectors, and Fig. 8 shows the connections to plug Pl. ORDERNG GUDE Panel, 615A (fuses are supplied with panel) Cable, A25B (one per panel) Assembly, Guide, P40V590 (three per panel, required for 108A U only). 3. NS ALLA lion 3.01 Mount the 615A panel on a standard relay rack or 16C apparatus mounting (or equivalent) using the 99-type bracket. Remove the center mounting bar from the 16C to allow the 615A to fit on the bracket. American elephone and elegraph Company, 1974 Printed in U.S.A. Page 1

Plug the A25B connector cable into plug Pl on the rear of the 615A panel. erminate the raw end of the A25B connector cable on the telephone company side of the 66Ml-50 interface connecting block according to standard even count color code. Follow the wiring plan shown in the section for the particular VCA being installed. Stencil lead designations on the 66Ml-50 interface connecting block as required. Note: When only the and leads (which are terminated at both plug Pl and the 66l connecting block) are to be extended from the 615A to the interface block, D inside wiring cable may be used instead of the A25B cable he customer must terminate the CPE on the 66Ml-50 interface connecting block using the terminals on the customer side Use D inside w1rmg cable to extend the and R leads from the CO or PBX connecting block to the 66l connecting block on rear of the 615A panel as shown in Fig. 6.

Customer-provided 24-volt or 48-volt de power must be routed through a KS protector before connecting to the power terminals on the 615A panel. Refer to Section for information on lhe KS protector. f the customer furnishes 48-volt de power, the 604B panel or the 604C with 21 apparatus unit installed must be used instead of lhe 615A for 101, 102, and 108-type Us When telephone company-provided power supplies are used (if required by VCA installation), the customer must provide a 105- to 130-volt, 60-Hz outlet within reach of available power cords (locally furnished). his electrical outlet should not be under control of a wall switch Refer to the appropriate section in Division 518 for proper grounding of power units. Proper grounding of equipment and power unit is important to prevent damage from power line surges. Page 3
