My take on it is... its out-of-band. It's
My take on it is... its out-of-band. It's just multiple logical channels
multiplexed onto a single physical channel. It doesn't matter that the
logical channels work together, the time slots remain dedicated to their
respective channels and the traffic doesn't mix.

So, here's a question for you all. I saw this on a practice test. Does ISDN
use "in-band" or "out-of-band" signaling and is it different for BRI versus
PRI?
Well, it's not robbed-bit signaling, from what I understand, which I guess
means it is "out-of-band"? The signaling has its own channel. But
Hi,
Yes, it is one D channel per PRI. An E1 has 32 timeslots of
64kbps (=30B +1D +1timing). A T1 PRI has 24 timeslots + rest
(=23D +1D). Timing is in the rest.
You can save D channels if put more than one E1/T1 in a bundle.
Then you need only one D channel per bundle.
So the answer is: not more
If I remember correctly there are 64 channels in a PRI ISDN. I could be
wrong it was one of things I memorized for my CCNA.

Just one D channel, used for signaling.

Europe 30B +1D

there is actually another channel for framing and synchronization in BRI
and
PRI T1/E1 and it's speed is as follows:
BRI = 48K
PRI T1 = 8K
PRI E1= 64K

PRI comes in two flavors, T-1 and E-1. T-1 has 23 b channels and 1 d
channel. What you describe in your question are the correct timeslots for
an E-1. Hopes that helps.

Hi All,
Quick question I hope you can help me with.
How many D channels does a PRI have?
I always thought it was two, but its states 1 in most places.
Text taken from the CCNP remote access guide (to make it more confusing):
there are 30 timeslots, leaving 2 timeslots for signalling and framin
