asterisk users - Sep 2003 - Connecting to an Ericsson AXT121 with a Digium Wildcat E100 card

Dear Telcotype Braniacs,

I have tried doing a google search to find out what this switch looks like, what
the physical interface is, but havn't been successful.  I am quite new to
the ISDN world so I'm not sure what to expect when I see this switch.  Does
anyone have any experience connecting to this switch?  The following is
basically all I have been given for info:

1) Ericsson, AXT121, interface ETCST (ROF 137 2764/2 rev R3A), Euro-ISDN.
Connected to FMV test network.
2) Subscriber normally synchronised (sync) from network.
3) 2,048 Mbit, 32TS-PCM, CCS in TS16.
4) HDB3, 75 ohm coax.
5) CRC check enabled.

Like I said, I am new to the ISDN world, my digium card has an RJ45 connection
type, what do I need to physically connect to the above mentioned switch?

I presume my zaptel configuration will be:
span=1,1,0,ccs,hdb3,crc4
bchan=1-15
dchan=16
bchan=17-31
loadzone=uk   (not sure whether this is correct for sweden?)
defaultzone=uk

and for zapata:
switchtype=euroisdn
signalling=pri_net
context=inc-e1   (or default...)
channel=1-15,17-31

Regards,

Sean Langley, P.Eng

Your configs look ok. All you need is BNC to RJ45 converter (I think the
standard is G.703)

regards
Martin
