The response time is, sadly, normal. The US has hands-down the best
telephone service in the world (scary, I know, but true). The Internet and
data services in Asia are where we were 5-10 years ago depending on where
you go. (Europe's better. Middle East is worse, as is South America). 

However, based on my experience with international data service, the packet
loss is not necessarily normal. Bug your IXC provider -- they likely ordered
the local loop from China Netcom, so they'll have to get them to fix it. It
may just be that they're on old, outdated, and possibly overloaded equipment
(in China, I think this frighteningly likely). But it's worth asking your
provider. Do you know if the E1 is backhauled from the US or if it's local?
