Description

CN50 (SCSI50) Female End

Uses standard 50-pin SCSI/CN50 connector, a high-density expansion interface for telecom switches and voice gateway equipment, capable of carrying multiple telephone signal lines on a single interface.

With locking screws and alignment slots for secure, anti-loosening connections, compatible with dedicated expansion interfaces on device rear panels.

RJ11 Crystal Head End

Terminal end splits into multiple RJ11 crystal heads (shown in parallel in the diagram), the standard interface for telephone lines, directly connecting to telephones, fax machines, or distribution boxes.

Each RJ11 corresponds to 2 pins in the CN50 interface, enabling expansion of up to 24 telephone lines from a single CN50 interface (of the 50 pins, some are for power/ground, with the remaining pins corresponding to 24 signal lines).

Cable Body

Cable uses a multi-core twisted pair structure to reduce signal crosstalk and ensure voice call quality; external braided sheath improves EMI resistance and abrasion resistance for long-term use in equipment rooms.

Each wire core is marked with a numeric identifier for quick cross-reference of circuit correspondence, facilitating equipment room wire and maintenance.

Application

PBX / Voice Gateway Distribution

This is the primary use, commonly found in enterprise and telecom equipment rooms: expanding the CN50 expansion interface of PBX switches (such as Panasonic, Siemens, Guowei, etc.) into multiple telephone lines connecting internal extensions, fax machines, or external lines.

Used for the distribution expansion of IP voice gateways, enabling single gateway interfaces to connect multiple telephone terminals.

Centralized Circuit Management in Equipment Rooms

Reduces equipment room wire complexity by consolidating multi-channel signal transmission through a single high-density cable, then distributing to individual terminals, facilitating centralized maintenance and fault isolation.
