Netshield X21 Compatible Cisco Cables

These cables are typically used between the NTU (Modem) and the Cisco/3Com Router. It is an X21 cable with a DB15 connector that can be either Cisco HD60PW standard (large connector) or Smart Serial (represents the size of a USB connector and is sometimes referred to as WIG 1/2 connector).  Standard length is 3m, but longer lengths are available.

The following will be typical questions to qualify which cable to purchase:

  • Determine which standard connector is required (Cisco HD60PW or Smart Serial)
  • Determine whether a DTE (DB15 Male) or DCE (DB15 Female) interface cable is needed
  • Determine the length of the cable that is needed.
