A broadcast control channel (BCCH) is a point to multipoint, unidirectional (downlink) channel used in the Um interface of the GSM cellular standard .
Read moreWhat is TCH in mobile?
GSM has two types of traffic channels TCH/FS and TCH/HS. It is used both in the uplink and downlink after mobile has established connection with the GSM cell (BTS). It uses 26 frame multi frame structure. TCH/FS stands for traffic channel at Full rate speech and TCH/HS stands for traffic channel at half rate speech.
