General request
With a general request (GR), a central station requests the current process image from the
connected nodes.
A general request is started automatically when a disrupted connection has been restored or
when a failed partner reports a restart. Apart from the automatic general request, a general
request can also be triggered by the user program or from the control center.
TD7onTIM does not support general requests.

General Packet Radio Service
Packet-oriented service for IP-based data transmission in GSM networks. The data is
transmitted using the Internet protocols TCP/IP or UDP/IP.
