Generally, layers are named by their specifications: [9] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
DMX512-A (ANSI E1.11-2008) defined the use of eight-pin modular (8P8C, or "RJ-45") connectors for fixed installations where regular plugging and unplugging of equipment is not required. Several manufacturers used other pinouts for RJ-45 connectors prior to this inclusion in the standard.

Typical network update rates are 1–30 kHz, but EtherCAT can be used with slower cycle times, too, if the DMA load is too high. The bandwidth utilization is maximized, as each node and each data do not require a separate frame. Thus, extremely short cycle times of ≤ 100 μs are achievable.
