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.
The other well-travelled cellular technology is CDMA. CDMA was developed by Qualcomm. The CDMA brand name encompasses two different standards: IS-95 aka CDMA One, a 2G digital service, and its modern 3G successor CDMA-2000.
