Cisco CAB-HNUL | HSSI DTE Null Modem Cable | For High-Speed Serial Interface & Router Interconnects

Brand:

Cisco

Specifications

Product Description

The Cisco CAB-HNUL is a High-Speed Serial Interface (HSSI) DTE null modem cable designed to connect Cisco routers or other networking devices in back-to-back serial configurations without requiring external modems or CSU/DSUs. Featuring HD-50 male connectors on both ends, this 10-foot cable allows direct communication between two DTE devices, making it a powerful tool for WAN emulation, lab testing, and legacy serial interconnects.

Features

HSSI Null Modem Configuration: Designed to cross transmit and receive signals, enabling direct serial communication between two routers or DTE devices.
HD-50 Male Connectors: Uses standard 50-pin high-density male connectors, ensuring a secure and robust connection to HSSI ports.
High-Speed Capable: Supports speeds up to 52 Mbps, in line with HSSI interface specifications.
Ideal for Testing and Lab Use: Perfect for WAN simulation, loopback testing, or router-to-router configurations without live WAN links.
10-Foot Length: Provides enough room for clean cable management in lab racks or test setups.

Specifications

Brand: Cisco
Part Number: CAB-HNUL
Cable Type: HSSI Null Modem Cable
Interface Type: High-Speed Serial Interface (HSSI)
