HP 480-0005-00-15 manual 21RJ-48 Port Pin Order DS1 Signal for DS1Card RJ-48 Ports

Chapter 2: Hardware Components

Span Status LEDs. The DS1 card contains eight Span Status LEDs, viewable from the front of the chassis, to provide a high level indication of the traffic status between the T1/E1 lines (also available on the rear of the chassis) and the network equipment (i.e., PBX or PSTN). Each LED relates to one line on the rear of the DS1 card.

•Off. SPAN is not connected. See Chapter 8: Diagnostics/Maintenance for a detailed description and troubleshooting techniques.

•Green. Line is operating properly.

•Red. Local alarm generated (i.e., loss of framing).

•Amber. Remote alarm generated (i.e., remote side has a problem and is sending a Yellow alarm).

Hot Swap LED. A lit blue light indicates that the DS1 card is not in service.

RJ-48 Input/Output ports. The eight RJ-48 connectors on the rear of the DS1 card (the transition module) are used to provide network access; they route signals between the T1 or E1 and a piece of network equipment (i.e., PBX or PSTN). The input/output signals are listed in Table 2-6.
