4.2.3 Downloading
4.2.3.1 Download procedures
Immediately after a successful establish request or indication, a terminal shall report its identification via
the Report Set ID response (see § 4.2.2.1). If the terminal requires a download, it shall set the Load Request
Bit (LRB) to 1. All subsequent Report Set ID responses (e.g. in reply to polls from the system) shall also
have this bit set until a Load Address command (see § 4.2.3.2) or Run command (see § 4.2.3.7) is received
from the system. After that time, all subsequent Report Set ID responses from the terminal shall have the
LRB set to 0.
The system may optionally send a Start B Channel command (see § 6.2.2.1.10) before continuing the
download sequence, in order to download the terminal over a B channel.
