Subject: 9. Can I use an analog (POTS) phone and a Pipeline 50/50HX on the same BRI?

The Pipeline 25 (to be released Real Soon Now), will have built-in POTS jacks, which means any analog device (phone, answering or fax machine, etc.) can be used on the BRI.. For those who already have P-50s or P-50HXs, using an analog phone on your BRI entails using an external NT1 that includes a POTS jack, such an ADAK NT1 or IBM 7845. These are fairly expensive, however, and you lose the ability to aggregate channels on the P-50, unless (as mentioned above) you're off an AT&T Custom switch.

Here's how Robin Cutshaw got this working with an IBM 7845 (NT1 + POTS jack) and Southern Bell: 

> I've got three SPID's: 2 type D for data/voice and one type C for voice
> only.  The voice only spid has two phone numbers associated with it,
> the primary and secondary.
>
> As per the IBM 7845 manual, chose terminal type C with EKTS and CACH
> (page5) and configure the keyset for the primary # as key 1 and
> secondary as key 11 (page 67).  Not mentioned in the manual is the fact
> that you should choose NI-1 (national).  All of the above setup is done
> by the phone company.
>  
> Then simply follow the manual for programming the 7845 using the primary
> spid/number.
>
> I'm using an SR3 distinctive ring splitter on the back of the 7845.  This
> This box came from Hello direct (800-HI-HELLO).  It seems to work fine
> with the two numbers that I'm using (but I haven't tried the max of 3).
>
> To get the 7845 to program properly, you need to disconnect the P50 from
> the ISDN line while programming.  I typically have one B-channel nailed
> up from the P50 with MPP bonding to the second for heavy traffic.  As
> long as I'm not using both B-channels for data, the 7845 seems happy.
