Key specifications

• Cable length: 10 metres
• Connector type: RJ-12 (6P6C) on both ends
• Colour: Black
• Intended signals: Analog voice and low-speed data for telephony
• Construction: Molded connectors with protective jacket

How to use

Insert one RJ-12 connector into the telephone base or wall socket and the other into the handset or extension port until the latch clicks. Route the cable to avoid sharp bends and pinching, and secure excess length to prevent tripping or strain on the connectors. For PBX or multi-line systems, verify the correct extension ports before connecting to avoid cross-connections. No specialized tools are required for typical plug-and-play installation.

Recommendations

Avoid exposing the cable to sustained mechanical stress, liquids, or extreme temperatures. When installing in shared workspaces, use cable management clips or channels to maintain a tidy layout and prevent accidental disconnection. Replace the cable if connectors become loose or if signal quality degrades.
