Description:

A shared library for MFC/R2 signaling on E1 lines

This library is designed to support MFC/R2 signalling in the
ZapTel environment, but should be easily adaptable to other dumb
E1 cards that allow channelised CAS signaled operation.

It is intended that the library eventually support most national
variants of the MFC/R2 protocol. The application specifies the
national variant when opening a channel.

*****WARNING*****

Don't expect too much right now. This software is very much at the
alpha stage right now. It doesn't support most national variants,
proper protocol error recovery, and various bells and whistles [I
guess, the whistling part must be OK, or the tone signalling
wouldn't work at all :-)]. It probably still has many bugs, since
it hasn't been polished and debugged very much right now.

*****On the brighter side*****

It can make and receive calls successfully when connected to a
Dialogic E1 card running the GlobalCall 2.0 package, in China and
Argentina modes.
