SV9500 - DND from Front Desk terminal doesn't work

[hcmbmt]

Hi all,
SV9500 is using for Hotel. I configured the DND on Front Desk Terminal but it doesn't work, either use Key on phone (press but not thing show on phone screen) or Feature access code (press and deny tone). Pls help to check if anything missing/wrong (or please share the working one).

- ASYD, SYS 1, Index 161, b2=1 (Language Service in Service)
- ASYD, SYS 1, Index 162, b5b4 =00 (destination for DND to ROT)
- ASYD, SYS 1, Index 170, b3 =0 (Restriction at the time of DND - RS Memory)
-ASYD, SYS 1, Index 172, b2 = 1
- AHSY, Index 77, b1 =1 (LCD Indication of DND)
- AHSY, Index 266, b2 =0: Sending a service feature text for DND to PMS
- ASFC, SFI 45 = 1 for Admin phone
- AKYD, Assign FKY 89 (DND Set) and FKY: 90 (DND Cancel)
- AANP
- AASP, ACC: #0, SRV: SSC, SID: 52 (DND SEt)
- AASP, ACC: #01, SRV: SSC, SID: 53 (DND Cancel)
Thanks,

Update for this case:
ASFC, SFI 45 =1 for Front Desk Terminal
Need to add below keys to Front Desk Terminal for DND Set:
1. DDS, FKY 89
2. DDR, FKY 90
3. Enter, FKY 99
4. End, FKY 101

How to set DND: DDS - Extension Number - Enter - End
How to cancel DND: DDR - Extension Number - Enter - End

And AKYD follows below layout
