Chapter 1: Product Description

HMS-318 List 3 Rear View

The HMS-318 List 3 shelf input power, 5-position terminal block (labeled TB1) and the alarms (labeled Alarms) wire- wrap connections are located on the rear panel (see Figure 1-2). The Bonding (Safety ground) is located on the upper right corner extension of the right panel. The label (BONDING WIRE MIN #10 AWG) is located on the right corner of the rear panel (see Grounding Lug and Hexhead Screw, Figure 1-2).

Managed HDSLx configuration

Also located on the rear panel, connectors P1 and P2 (labeled CO PAIR 1 and 2) are DSX-1 receive and transmit connections. Connectors P3 and P4 (labeled SPAN PAIR 1 and 2) are HDSL Spans (Loops 1 and 2) receive and transmit connections (see Figure 1-2). All of these plug-in connectors (P1, P2, P3, and P4) are 50-pin Amphenol- type male connectors and provide Tip and Ring for all the cards in the shelf. For information on the signal and pin assignments, see Appendix A: ”Signal and Pin Assignments” on page A-1.

LoopStar™ (LPS-300C) Power Module configuration (for Wi-Fi)

Also located on the rear panel (for Visual & Audible Alarm Contact operation, install an HMU-319), connectors P1 and P2 (labeled CO PAIR 1 and 2) are xDSL B and A IN transmit and receive connections, respectively. Connectors P3 and P4 (labeled SPAN PAIR 1 and 2) are xDSL A and B OUT transmit and receive connections, respectively (see Figure 1-2). All of these plug-in connectors (P1, P2, P3, and P4) are 50-pin Amphenol-type male connectors and provide Tip and Ring for all the cards in the shelf. For information on the signal and pin assignments, see Appendix A: ”Signal and Pin Assignments” on page A-1.
