This page describes the GSM Standalone Dedicated Control Channel (SDCCH). The SDCCH is a signaling channel that exists between a GSM Mobile device and a GSM BTS (Base Transceiver Station).
This SDCCH channel operates independently of the TCH (Traffic Channel).
It’s always present, and there’s no “frame stealing” required, which simplifies the communication process.
Explore the differences between SDCCH and SACCH channels in GSM, their roles in signaling and measurement information exchange, allocation, and timing within the GSM network.
Learn about the GSM Fast Associated Control Channel (FACCH), used for rapid information exchange between a mobile station and base transceiver station.
Explore GSM's SACCH, used for power control, timing advance, and neighbor cell measurements during active calls.
