how i can reduce this delay ?

Thanks

are you using LCR programming or direct access?

In CM200 what is 9 set to?

D

It's LCR programming

Also there is no command like CM200

please advise

Yes, there is a cm200, your issue is likely in cm85x, if you are using LCR. If you don't understand that verbiage, time to call a tech. I charge a fees for in-depth assistance such as this.

The command is actually 20x.

1. Take note of, or set the sense wheel on the 24PRTA/B/C card e.g. 06
2. CM 050>06>12Set the Sense wheel of the 24PRT card (06) to a type 12for ISDN PRI.
3. CM 0608>0>06Set the DCH channel (0~7) to the sense wheel of the 24PRT card (06).
4. CM 0701>0600~0623>D200~D223To the sense wheel of the 24PRT card (06), assign to each channel
(00~23) a trunk (D200~D223). All channels should be assigned.
5. CM 3000>200~222>20 Place each Voice trunk (200~222) assigned in step 4, to a trunk route (20).
CM 3000>223>21 Place the D channel trunk (223) assigned in step 4 to its own trunk route (21). NOTE:this
must be the 24
th
channel of the span.
6. CM 3002>200-222>18Assign each Voice trunk (200~222) to ISDN in-dial (18) in Day Mode.

8. CM 3040>200-222>18Assign each Voice trunk (200~222) to ISDN in-dial (18) in Mode A.
9. CM 3041>200-222>18Assign each Voice trunk (200~222) to ISDN in-dial (18) in Mode B.
10. CM 3007>200-222>000-022To each Voice trunk (200~222) set a Circuit Identification Code (CIC,
000~022). NOTE:No CIC should be assigned to the D channel trunk (223).
11. CM 3500>20>00 Set the voice trunk route (20) type to CO (00).
12. CM 3504>20>2 Set the voice trunk route (20) to Answer signal arrives (2).
13. CM 3509>20>08Set the voice trunk route (20) to ISDN incoming signaling (08).

15. CM 3518>20>0 Set the voice trunk route (20) to allow DID/DNIS digit conversion with CM 76 (0).
16. CM 3528>20>0Set the voice trunk route (20) to disallow Trunk Queuing.
17. CM 3590>20>3Set the voice trunk route (20) to ISDN PRI.
CM 3590>21>3Set the D channel trunk route (21) to ISDN PRI. NOTE:This is the onlyCM 35 bit set for
the D channel trunk route (21).
18. CM 3593>20>00 Assign the Voice trunk route (20) to the ISDN DCH channel set in Step 2.
19. CM A900>0>223 Assign the DCH channel (0) to the DCH trunk (223). NOTE:this must be the 24
th
channel

20. CM 410>50>05 Set the timing start for ISDN calls to 5seconds.
CM 410>57>05 Set the timing start for ISDN tandem calls to 5 seconds.
21. CM 482>04>0 Enable 2
nd
dial tone sending on ISDN trunks.
22. CM AA00>06>0 Set the sense wheel of the 24PRT card (06) to AT&T Specifications (0).
23. CM AA06>06>20/21/28To the 24PRT sense wheel (06) assign an ISDN protocol. 20= AT&T, 21=
Northern,28= NI2.
24. CM AA14>06>0/1 For the sense wheel of the 24PRT (06) card assign the type of ISDN card being utilized.
0= 24PRT, 1= SC01.
