The two most commonly used prescription anti-seizure medications for pets are phenobarbital (PB) and potassium bromide (KBr or K-BroVet Potassium Bromide). Diazepam is not used to prevent seizures in dogs because the effects last about 20 minutes.
In radio systems, TDMA is usually used alongside Frequency-division multiple access (FDMA) and Frequency division duplex (FDD); the combination is referred to as FDMA/TDMA/FDD. This is the case in both GSM and IS-136 for example.
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern.
