Caller ID - PRI into Atlas 800 , then TA750

Caller ID - PRI into Atlas 800 , then TA750

(OP)
Hi, I have two PRIs feeding an Atlas 800 from which I'm looping from the T1 port down to a TA750 for some analog lines.

Regarding setup, I would say that, except for the dial plan entries, it's very vanilla. I don't think I changed much at all from the default, factory settings.

Until recently, I've never needed CID outputted from the TA750 but now I'm trying to make that happen.

Can someone suggest some things to check either in the Atlas or the TA750 which would keep caller ID from being relayed through? (I'm fairly certain it's being transmitted by my circuit provider but I am double-checking that.)

Thanks for anyone's assistance.

RE: Caller ID - PRI into Atlas 800 , then TA750

How do you plan to convert PRI DCH info to DS1 CAS on a per channel basis for your analog lines? You should probably check the Atlas 800 documentation to see if that feature is supported. You need something to do a translation of BCH & DCH on the PRI to provide the channel signalling to drive the analog line FXS channel unit of the TA750. Otherwise it will never work! Primary & Basic Rate ISDN are digital services, not an analog service. FXS channel units convert the digital signals to analog. The TA750 only accommodates DS1 full or fractional for facility connections, and only Basic Rate ISDN on the output side for one of its options, but not PRI.

Hope this helps!

Hey Jim,

Thanks for your reply. I did find this info on the Adtran site:
https://supportforums.adtran.com/servlet/JiveServl...

but am unsure of how to interpret it mainly because I'm not familiar with lots of the telco terms used in it. I have a feature called "Real-Time ANI" active on some toll free numbers which come in on my PRIs. I've been told by my supplier that they don't offer CID over these circuits, only the Real-Time ANI.

This Adtran PDF document seems to indicate I cannot translate ANI to CID at least in "switched mode" but I don't know what that means.

Does this document help shed any light on my question?

Thanks again.

RE: Caller ID - PRI into Atlas 800 , then TA750

I checked your link and downloaded the document, and the Atlas800 user guide from Adtran. I believe the Adtran document in regards to ANI numbers means that the Atlas800 does NOT translate ANI to CID format. If your PRI ISDN provider is using a standard PRI format, CID presentation info should be there. The real time ANI is only associated with TollFree number service not local or POTS type. PRI can handle both formats. Since it is done on a call-by-call basis, this is done during call setup. You mentioned you have more than one PRI, are the services delivered a single type per PRI or are you getting multiple services on the same PRI(s)? You mentioned above that you currently have loop-start lines working on your TA750 thru the Atlas800. That being the case, you should review the Atlas800 User Guide chapter 9, which covers the Dial Plan configurations for what you are doing, and any other related sections. If the Adtran glossary does not help with some of the telephony terms, you can post here, or try Wikipedia for more expansive descriptions. If you are still confused about configuring the CID in the Dial Plan don't hesitate to call Adtran tech support. I have always found them receptive and helpful.
