Good day! I am hoping that I can find some guidance on some elementary concerns and questions, for a current project.
A customer of ours has a Comcast PRI via a Arris CM820 (basic cable modem) which hands off to their Adtran 908e. I do not know the Gen. /firmware information as, we do not have access (we tried)to the unit. The Adtran (T1/03) plugs into a PRI blade on their Panasonic PBX (Panasonic is being replaced, hence why I am here).
Since there are eight legacy devices that require analog (fax machines) - the first question I have is: could we utilize the 25 pair amphenol (first eight) voice port and wire it up to a block,, isolating those devices from the new PBX? Not having much knowledge on the 908e besides some reading - it seems that it would.
If in fact we could utilize that 50 wire voice port - the next question is, how much is involved configuring the Adtran, to provide dial tone from Comcast's PRI?
Comcast has hinted that if they come in, and breakout the analog lines for their fax machines - they'll install an 8 port eMTA (pretty sure about that), and will definitely incur an additlional hefty monthly charge, which we are trying to help avoid. Full disclosure: we are installing a new NEC SV9100. The chassis is full with digital port cards. We can solve this be adding an expansion chassis with an analog card (for a one time fee), but we wanted to learn if the Adtran could solve the hiccup. (customer thought analog was already isolated = but was wrong and new equipment was already ordered)
The last concern!!! If in fact the Adtran can isolate trunks from Comcast PRI for their fax machines - we do not have access to the Adtran. We tried the default IP and credentials and it did not work. So, is there a back way in or is that something we would need to ask Comcast - or is there a quick way to track down the IP? Their existing PBX is all digital and analog.
Thanks in advance
