A framer is a component in charge of an E1/T1 line interface.
Connected usually to a TDM bus, it converts TDM frames to/from E1/T1
frames. It also provides information related to the E1/T1 line.

QMC channels support runtime timeslots changes but nothing is done at
the QMC HDLC driver to handle these changes.
Use existing IFACE ioctl in order to configure the timeslots to use.
