PCM-KW-605 is a Cisco-compatible RS-449 DCE serial cable designed as a reliable, cost-efficient alternative to Cisco CAB-449FC (Part No. 72-0796-01).

 

This cable connects Cisco routing platforms to external communication equipment using a DB60 (LFH60) male connector on the Cisco side and a DB37 female connector on the network side, conforming strictly to the RS-449 DCE specification.

 

It is commonly deployed in legacy serial WAN environments where the Cisco device functions as DCE, supplying clocking to downstream equipment.

Rather than rebranding generic serial cables, PCM-KW-605 is engineered from the pinout up for RS-449 DCE applications. Every conductor, termination, and shielding decision is made to ensure electrical correctness and long-term operational stability in enterprise and industrial networks.

This makes it an ideal replacement cable for maintenance, spare inventory, and infrastructure continuity projects.

 

 

RS449 DCE Cable is suitable for use with:

 

• Cisco 7000 Series
• Cisco 4000 Series
• Cisco 2500 Series

 

 

Using Cisco Compatible CAB-449FC allows network operators and integrators to:

 

• Maintain correct DCE/DTE role assignments
• Avoid timing and handshake errors
• Reduce dependency on discontinued OEM cables
• Secure consistent supply for future maintenance

 

All assemblies are electrically verified to match Cisco's original functional behavior.

 

Unlike generic third-party serial cables, PCM-KW-604 is built specifically for Cisco RS-449 DTE environments, ensuring:

 

• Correct signal direction and handshaking
• Stable transmission over extended operating cycles
• No modification or adapter required
• Lower total cost of ownership compared to OEM sourcing

 

As a cable assembly manufacturer, we control conductor selection, termination quality, and final testing - not just trading parts.

 

 

 

Q1: How can I confirm whether I need a DCE or DTE RS-449 cable?

A1: In RS-449 serial links, DCE provides clocking while DTE receives it.
If your Cisco router is configured to supply clock rate (clock rate command on the serial interface), you need a DCE cable like PCM-KW-605. If the clocking comes from the external device, a DTE cable should be used instead.

 

Q2: Does PCM-KW-605 include clocking lines required for RS-449 DCE operation?

A2: Yes. The cable is fully wired for RS-449 DCE, including transmit, receive, control, and clock signal paths. It is not a partial or reduced-pin assembly.

 

Q3: Can this Cisco compatible CAB-449FC cable be used with CSU/DSU or legacy telecom equipment?

A3: Yes. RS-449 DCE cable is commonly used between Cisco routers and CSU/DSU, modems, or telecom devices that require a DB37 female RS-449 interface.

 

Q4: Is PCM-KW-605 tested before shipment?

A4: Each cable is electrically tested for continuity and pin accuracy before shipment to ensure correct RS-449 DCE functionality.
