So I converted my trunk group from a FAS platform, to an NFAS platform. Basically I went from individual D channels for each T1, to a primary/secondary D channel.

When I did this I was able to change the 24th channel from each T1, to a B channel.

Here is my dilemna... Any of my incoming calls that hit a 24th channel, get's an extremely loud static sound. Kind of like a radio station out of tune.

After busying out the 24th channel for each span, the noise went away.

In the process of identifying the problem, I received the following email from MCI...

Folks,

Worked and issue yesterday where incoming or outgoing callers on time slot
24 would hear a loud noise similar to monitoring a data call with a TUBER.
The customer had 166Bs and 2D. Each T1 had the noise on channel 24 except
for two span which had the d channels, of course.

Apparently the T1 interface cards have some firmware and it needs to be
RESET. The customer had used these 5 T1 card previously in another PBX where
the were "administrated" as 23B+1D. Once the RESET was complete the noise
was gone. The card firmware was reloaded/administrated as "ISDN-extended"
which mean all 24 channels are Bs.

Now, my question is this... How do I reset the firmware to the DS1 boards, or is this something that Avaya would have to do?

Thanks in advance for any help!
