Also, while now the ISDN link is up, and we are able to make some calls thru the new line, we have two error messages going on the asterisk console: When asterisk start, or when the PRI reset, every channel trigger this message: [Jan 19 21:01:17] ERROR[13512]: chan_dahdi.c:8413 dahdi_pri_error: !! Unexpected Channel selection 3 -- B-channel 0/1 successfully restarted on span 2 [Jan 19 21:01:17] ERROR[13512]: chan_dahdi.c:8413 dahdi_pri_error: !! Unexpected Channel selection 3 -- B-channel 0/2 successfully restarted on span 2 ... And this one: Unable to handle return result on switchtype 5! happen on a regular basis, i'm not sure but it look like jsute before the outgoing call is bridged to the internal extension. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

That was it, i tested my cable with a multimeter, but i have been caught by the mirror effect on the diagram. Rebuilding the cable using correct numbering and voila! The link is up now ! Thanks a lot (and a trick for the telco tech that assured me a straight cable would work). ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Hello Benoit,
Le 16.01.2009 22:29, Benoit a écrit :
And work quite well, i've duplicated this for the access thru the One400
box:
span=2,0,0,ccs,hdb3
bchan=32-46
dchan=47
With no luck until now. I'm reading the one400 manual, and here are the
defaults setup for the PRI interface:
CLI(config)# interface pri 5/0
CLI(config-if)# physical-interface E1
CLI(config-if)# framing Df
CLI(config-if)# linecode hdb3
And here are the available framing:
CLI(config-e1)# framing {none | df | mf | emf}
Specifies the framing type.
None: no framing. Only used for CES / unstructured mode
Df: double frame, no CRC4. For E1 only. (Default value)
Mf: multiframe (CRC4). For E1 only
Emf: extended multiframe (CRC4). For E1 only.
Sf: Super-frame (for T1 only)
Esf: extended super frame (for T1 only)
However there is no references to this 'double frame' mode in the
dahdi/system.conf span configuration options
# framing::
# one of 'd4' or 'esf' for T1 or 'cas' or 'ccs' for E1 and BRI.
# 'd4' could be referred to as 'sf' or 'superframe'
I read somewhere (can't remember where, sorry) that double
framing is equivalent to basic framing. Presumably it is also
equivalent to no crc. If that's correct, then I would say you
can use the same setup as you have with FT, it looks good to me.
As regards the cable to be used,
Also, i've used a straight Cat5E to connect the One400 to the TE220, both
seem to share the same Pin setup:
One 400:
1: RX (+)
2: RX (-)
4: TX (+)
5: TX (-)
TE 220:
1: RX
2: RX
4: TX
5: TX
Should i do some special crossing cable instead ? connecting Tx from one
side to other side Rx ?
yes, if both sides have the same pin assignments then I'm pretty
sure you should use a crossover cable.
Exact pin assignment for crossover is
Pin 1 --- Pin 4
Pin 2 --- Pin 5
Pin 4 --- Pin 1
Pin 5 --- Pin 2
Not *totally sure* mind you, because I had a recent experience
with a Telco where a straight cable should have worked, but
didn't, so I built a crossover cable and that worked...

They must came back to 'test and validate the line' so i'll have to wait until that since they don't wan't me to look into the gateway configuration.. :( ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Those terms would be ISDN-related. VN4 is Version Number 4, and
ETSI is the European standards-adopting organization for telecoms.
So you might want to check for E1 support (ISDN in Europe,
basically) if you want to connect a PRI-capable equipment - I
assume that's what you are looking for since you mentioned the TE220.
If you read French, you might want to look at this page also:
http://blog.nicolargo.com/2008/01/installation-dune-carte-digium-avec-asterisk.html
I found it very useful when I installed recently a TE220 card.
Hi,
yes it's for connecting an PRI line. In fact i already have one PRI
connected to a 'real' PRI line,provided
by France Telecom. But this one is a little bit special, it's for
connecting to this kind of box:
http://www.oneaccess-net.com/en/one400.htm
Which is a SDSL/PRI gateway (yes, i asked for a direct SIP/H323
connection, but it's not in our product line was
the only answer ..).
Until know the L1 link doesn't goes up, so i'm looking for every bit of
info i can use. The FT line is configured like that:
span=1,1,0,ccs,hdb3
bchan=1-15
dchan=16
And work quite well, i've duplicated this for the access thru the One400
box:
span=2,0,0,ccs,hdb3
bchan=32-46
dchan=47
With no luck until now. I'm reading the one400 manual, and here are the

Sf: Super-frame (for T1 only)
Esf: extended super frame (for T1 only)
I also found this:
The ONE 400 supports CCS mode (transport of
signaling messages over a D channel). CAS (Channel Associated
Signaling) mode is not supported.
However there is no references to this 'double frame' mode in the
dahdi/system.conf span configuration options
