I'll try to to send a 10-pages long fax and report here my findings.
2 pages are enough to see whether there are any problems.
As far as P2MP signaling is concerned, you can hook up to 8 devices (64 <= TEI < 127) to such a
PSTN connection. To simplify installations, there is usually a bus top

Anyway, refering to http://en.wikipedia.org/wiki/Integrated_Services_Digital_Network / Basic
rate Interface paragraph, my setup includes :
- a single network termination unit, installed and managed by telco, is connected to public
network through 2 twisted pairs,
- this unit includes two sma
So it seems common from Telco to turn ISDN lines going down and up, once in while and this is
not for energy savings.
I don't think so. There is another reason for you problem.

I double-checked with other locations (also using Patton devices and I
didn't get any complain). I can find the same pattern everywhere:

At the moment, I'm having trouble with lines going up and down all day long.
I asked them to be created as P2P.
Mostly but not always calls are passing in and out correctly.
I doubt that the energy-saving is causing the trouble. How do you get the ISDN-signal? Is it an
S0-bus? If yes, I may be a

At the moment, I'm having trouble with lines going up and down all day long.
I asked them to be created as P2P.
Mostly but not always calls are
So if my understanding is correct, Energy Saving mode exists in P2P BRI lines.
No, not for P2P lines, only for P2MP lines.
How do you monitor these lines ?
Most of the time I use a vendor specific utility, but "pri show spans" gets the
status as well.
Have you also heard about this spec

Yes, I can confirm that. P2P always requires a PBX and you can easily build up trunks of P2P
connections. So all channels always need to work in a coordinated way, if you allow this sloppy
formulation. Another reason for not allowing the energy saving mode is probably that in some

Hello,
I always thought that Energy Savings mode existed with ISDN Basic Rate
Interface in Point -to-multi-Point but it didn't with Point-to-point.
Is this correct ?
Have you ever met a public PSTN switch configured to "cut" B ISDN channels
in Point-to-point.signalling ?
Regards.
