Page 22: Chapter 3 Module Operation
In the message-based mode, the 1260-01T switch controller interprets commands sent by the slot 0 controller, and determines the appropriate data to send to the control registers of the 1260- 64M module. A conceptual view of the message-based mode of operation is shown in Figure 3-1. - Page 23 1260-64M module. The 1260-01T command module does not monitor these operations, and does not keep track of the relay states on the 1260-64M module in this mode. A conceptual view of the register-based mode is shown in Figure 3-2 below.
