[asterisk-users] PRI span configuration - span remains down

[David Kennedy]

Hi,

I'm trying to connect to Telewest/Virgin Media with a TE110P using
asterisk 1.4.13/zaptel 1.4.6. No matter what I try, my span always
appears as

PRI span 1/0: Provisioned, Down, Active

My zapata.conf is currently
-----------------------------------
[channels]
echocancel=yes
echocancelwhenbridged=no
echotraining=yes
switchtype=euroisdn
contect=from-pri
signalling=pri_cpe
group=1
channel => 1-15
channel => 17-31
-----------------------------------

zaptel.conf is
-----------------------------------
span=1,1,0,ccs,hdb3,crc4
dchan=16
bchan=1-15,17-31
loadzone=uk
defaultzone=uk
-----------------------------------

I'm in London and the server is in Manchester, so I can't look at the
server directly, but when we first started setting it up, apparently a
pair of cables were the wrong way round, so the card was in a RED
alarm state. We've switched the cables and now the card is OK. We did
have a lot of IRQ misses, so we've upgraded the kernel and now the
accuracy reported by zttest is about 99.98%. Telewest have checked the
line for faults and have reported that it's fine, but I just can't get
it working.

Does anyone have any ideas/suggestions?

Thanks,

Dave
