[asterisk-users] Newbie in China: Red alaram in Zaptel for E1

[Steve Underwood]

Hi John,

In China you will generally get either MFC/R2 or EuroISDN. MFC/R2 is 
much more common.

The only oddity with EuroISDN is that it often provided without CRC4. 
That doesn't make a lot of sense, but there it is. MFC/R2 seems to be 
universally provided without CRC4 in China.

You said you are sure the card is OK. How did you determine that? Have 
you tried a loopback cable between two its its ports? Are you sure the 
cable you have used is OK?

Regards,
Steve
