1. Maintenance bits are sent with meaningful data (‘Normal’ field in Table 5, T1E1.4).
2. linkup, SFS, aip_tp correspond to NR1 bits 3, 1, and 0, respectively.
3. No change in upstream maintenance bits: act = 0, sai = 0.
4. Because the upstream sai bit was set by the (upstream) AR command, the indication UAI will never be issued and
AR continues to appear on the C/I channel.
5. The downstream act bit is set by issuance of the AI indication.
