GCI ACTIVATION AND DEACTIVATION TIME DIAGRAMS

This section contains the time flow diagrams that detail the various activation and deactivation scenar-

ios for the MC145572 U–interface transceiver. Figures 8–9 through 8–17 are the activation diagrams

for the MC145572 operating in GCI mode. Figures 8–18 and 8–19 are the activation state diagrams

for NT and LT mode operation.

NOTES:

1. No change in transmitted maintenance bits at this time.

2. Maintenance bits are sent with meaningful data (‘Normal’ field in Table 5, T1E1.4).

3. linkup, SFS, aip_tp correspond to NR1 bits 3, 1, and 0, respectively.

4. No change in upstream maintenance bits: act = 0, sai = 0.

5. The downstream act bit is set by issuance of the AI indication.
