EIA/TIA-530A serial cable assembly

All serial cables provide a universal plug at the interface card end. The network end of each cable
provides the physical connectors most commonly used for the interface.

All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug
connector at the network end, and DCE with a receptacle at the network end. The V.35 service cable
assembly is available in either mode with either gender at the network end.
