CS1000E CEQU PRI

[DisasterMaster]

Below is a screenshot of CEQU on a release 7.6 cs1000e.
Why is the DCH value shown on some PRIs as DCH 23 and some 24 and how do you change the value.
I just added PRI Loop 84 and it automatically set the DCH as 24.
I don't recall a parameter in LD 17 that allows me to define 23 or 24.
Does Loop 84 think it is a T1 rather than PRI?

do they all have DCH configured or are they NFAS? all ours have individual DCH's so they all show 24 can you prt the dch's

 

[DisasterMaster]

No NFAS here.
All my circuits are PRI that have their own D channel.
This particular PRI is going to be configured as a TIE line to a Cisco router.
I will be using a UDT card that has yet to be placed in a 1010 shelf.
I know once I install the card I will need to make a serial connection to config the card but until I get the card, I wanted to go ahead and config the PRI then ADAN the route etc.
I see nothing in the NTP that shows how to set the value and what it really means.

This is what the book shows. I see no parameter that is relative to a 23 or 24 DCH value.

I believe its set when you add the loop as a PRI in CEQU

Thanks,

All Loops in my switch are configured as PRI. When printing CEQU in LD 22, some show DCH as 23 and some show DCH as 24. I still don't understand or can find documentation that states what the DCH value is actually referring to. When adding a PRI in LD 17, I see no parameter that references this value. It just shows up as 24 instead of 23 like most others. I have no explaination as to how loop62 shows up as 24 either. This makes no sense. I hope someone out there can provide documentation or personal excrescence as to why this happens and exactly what it means. The next step in the building a PRI is to create the ADAN. I don't want to proceed until I get a good answer to this. Thanks to anyone who can explain the theory here.

What do you mean next step is to create an Adam?

 

[DisasterMaster]

Yea, after I create an Adam, the next step after that is to create an Eve.

Actually, I figured this out. The format for DLOP is Loop/#of Channels/Framing.

 

[bignose21]

so by ADAN you mean config the DCH? then I guess it says 24?

 

[bhassell2000]

Yes in the CEQU when you get to DLOP you have to put a number in, I have never had it make a difference if i out 23 or 24

Thanks,

You can put in 23 or 24, makes no difference. The paramater is there for fractional T-1's/PRI's. But truthfully, why ever use anything other than 24. After all you still have to configure the trunks in ld 14.

 

[mckinneyj]

This setting is not for the D channel at all. It is a setting to state dd = maximum number of simultaneous voice
or data calls 0-(24). I had to look back in an old release 4.5 doc to find this
