Hello, I've connected a TE110P from digium with a E1/T1 crossover cable, according to http://www.voip-info.org/wiki-crossover+T1+cable, to a s2m port on a Siemens Hipath 3750. The lights on the TE110p are flashing red and green, zttool reports "Yellow Alarm" Asterisk says: pri_dchannel: PRI got event: Alarm (4) on Primary D-channel of span 1 pri_find_dchan: No D-channels available! Using Primary on channel anyway 16 chan_zap.c:5647 handle_init_event: Detected alarm on channel 1: Yellow Alarm chan_zap.c:5647 handle_init_event: Detected alarm on channel 2: Yellow Alarm [...] /etc/zaptel.conf ================span=1,0,0,ccs,hdb3,crc4 bchan=1-15,17-31 dchan=16 loadzone=fr defaultzone=fr /etc/asterisk/zapata.conf ========================[channels] context=remote pridialplan=local prilocaldialplan=local usecallingpres=yes busydetect=no callprogress=no callwaitingcallerid=yes echotraining=no echocancel=no echocancelwhenbridged=no overlapdial=yes immediate=no callerid=asreceived language=de rxgain=0.0 txgain=0.0 switchtype=euroisdn signalling=pri_cpe group=1 channel => 1-15,17-31 I modified the span line in zaptel.conf to span=1,1,0,ccs,hdb3,crc4 which makes no difference When I modify it to span=1,0,0,ccs,hdb3,crc4,yellow I get "Yellow Alarm/Not Open" in zttool. Any ideas? Regards, Henry
I had this problem in Africa. I was not provided any docs fromt he telco but the problem was the crc4. when omitted everthing was fine. ----- Original Message ----- From: "Henry Jensen" <hjensen@gmx.de> To: <asterisk-users@lists.digium.com> Sent: Tuesday, April 05, 2005 12:04 PM Subject: [Asterisk-Users] TE110P/Hipath3750 - Yellow Alarm> Hello, > > I've connected a TE110P from digium with a E1/T1 crossover cable, > according to http://www.voip-info.org/wiki-crossover+T1+cable, to > a s2m port on a Siemens Hipath 3750. > > The lights on the TE110p are flashing red and green, zttool reports > "Yellow Alarm" > > Asterisk says: > pri_dchannel: PRI got event: Alarm (4) on Primary D-channel of span 1 > pri_find_dchan: No D-channels available!

I had a DB15 connector and when I got mad that it wasn't working like it was specified I cracked the connector open and found a weird non standard wiring from rj45 to db15. I twisted the wires like they were supposed to but then this blinking problem of yours occured to me and it vanished when I told Hicom to be the master of the line and * the slave. As from that point I got some minor errors in d-channel protocol which seem not to interfere with operational service although the d-channel went done for once for no obvious reason. Jens

Try looking for an error message at the remote end. It may be as easy as a broken cable (where the Hipath does not hear the Asterisk box). Peter
Hi,> this blinking problem of yours occured to me and it vanished when I told > Hicom to be the master of the line and * the slave.How exactly do I tell asterisk to be the slave? AFAIK "signalling=pri_cpe" in zapata.conf means, that asterisk is the slave, and "signalling=pri_net" means master, or do you mean something different? Regards, Henry

The timing is configured in the span line of zaptel.conf and in your Hipath equipment. Peter
