[asterisk-users] what interface for ISDN-10/20/30?

<html><body><span style="font-family:Verdana; color:#000000;
font-size:10pt;"><div>Hello all,</div><div>I'm
working with one of our offices (that is moving soon) and they're being
offered ISDN-10/20/30 services from their TELCO. I'm wondering what kind of
interface card I will need (I prefer using Digium's cards). Are the
TE121/122/ or TE212/220 series cards compatible with this kind of service? Seems
like the service would look like a PRI interface, but I'm not sure. The
office is in
Singapore.</div><div><br></div><div>Thanks</div><div>Cassius

Yes, you are right. That's an E1 circuit, configured with 10, 20 or 30
active B-channels.
