Repeater Call for client nodes

The Repeater Call service is started by a Client node in accordance with the details

presented in

[2]. By pressing the CMD_RC Request button with the parameters presented in

Figure 43 properly filled, the GUI performs both operations:

●

send a MAC data request command to the connected modem following the upper

protocol layer specifications for Data Payload; the Payload window automatically

switches to the RC Request (BASIC) item; the data transmission takes into account the

credit parameters expressed in the GUI (the IC parameter must be greater than 0 so

that the modem can accept the RC Request)

●

send an RC Request to the modem while powerline transmission is in progress to

respect the RC mechanism, with the TX_POS, RC_THRESHOLD parameters

expressed in the GUI.

In order to activate the Repeater Call service for server nodes, the MIB object 000Bh

(repeater settings) must be written to either a “No” or “Yes” value through the referred ring

menu from the MIB panel, as in Figure 44.
