the people with the white coats will arrive soon (i placed a call), hold on, we on this thread will support you until they arrive. i believe the following should put you in the abyss.

I am working against a Southwestern Bell 5ESS and SW Bell has
established a tarrif in which no more than 2 SPID's are issued against a
single BRI line. Sad but true. And I, like Michael, had a lot of
trouble getting the line to work with both a Pipeline 50 and an IBM 7845
connected. My experience in getting things to work are slightly
different and may be of use to others in Soutwestern Bell land. I am
inserting my comments into the very useful document provided by Michael
Loceff in the hope that a recipe can speed others along.
: Here's the breakdown:
: Pac Bell:
: 1) 2 numbers and SPIDS
: 2) Each with voice/data
: 3) End one additional call appearance.
: 4) Both set to C terminal type (the 7845 wants C, the
: Ascend prefers A or B, but it accepts C,
: so for symmetry, I have C on both).
: Ascend:
: 1) Point-Point NOT NOT NOT Multi-point.
: 2) Give it either number as it's one and only (A) number.
: 3) Since you are doint point-point from the Ascend's POV
: there are no SPID questions to answer.

4) After bringing up the Ascend in Point-to-Point, I couldn't
make an outgoing call. This is what I expected, because
it WAS a multi-point line and all devices on a multi-point
need an SPID. However, -=THIS IS IMPORTANT!!=-,
the ATTEMPT to place a call apparently allowed the
5ESS switch to identify a second device on the ISDN line
because NOW, when I told the Ascend P50 to go into
multi-point mode, the line status indicatator came up
saying "M" in the display, not "D" as it had
in all previous attempts. SUCESS!!!!
5) I set the two phone numbers and the two SPID numbers to the
same value on the Ascend P50.
: IBM 7845
: 1) Program it using the other phone number (*98 ... #) and its
: corresponding SPID (*99 ... #).
: 2) For my area I had to speficy the 5ESS-Custom switch type
: (*97 5 #)
: 3) You can turn on extended mode and leave it on (*#9)

3) IS IMPORTANT, because the registration of the IBM 7845
with the 5ESS MUST occur before the Ascend P50.
: Even if you want to use both B channels for data simultaneously, you
: won't have to touch the 7845. I don't know why it works, but
: at Ascend they told me if I have 2 SPIDs I would have to set the
: 7845 as Multi-P and put in both SPIDS to get both B channels to work.
: That was not only not true, but nothing worked if I did that.
: Once I figured out the above, with hints (some correct) from IBM (Hi Chuck)
: Ascend (Hi Matt), Pac Bell (Hi Joyce) and Internex (Hi Randy), I didn't
: have to resort to the following two measures, which I employed
: several times during learning:
: A) When re-programming the Ascend, power cycle it once if
: it doesn't appear to change switching modes viz-a-viz
: it's Switch Type status window.
: B) If Everything looks good but you can't PING out - i.e. no
: dial, call the Ascend number from a differet
: line to wake it up - you should see it's B1 channel
: status change from - to *.
: Oh, while I can't seem to get the Ascend to automatically increase
: bandwidth yet, I can force is by asking it to originate calls
: on both B channels. (I must say, the documentation for both the Ascend
: and IBM units is - well I don't want to start anything.)

The above information helped me get this working. I want to thank
Michael for work he did in figuring this out. |
