What is the second step in manual signaling?

The second step in manual signaling involves "keying in a three-digit code to connect." This step is crucial because it establishes a communication link between the sender and receiver before any further conversation takes place. Properly connecting through a specific code ensures that the intended recipient is reached, enabling effective communication.

Following this step, other important actions typically involve identifying oneself and stating the reason for the call. However, those steps occur after the connection has been successfully established. Thus, the process emphasizes the need for the correct code entry to facilitate timely and coherent exchanges.
