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.
