* xpd_echo (card_echo.c) - a module to handle an Astribank hardware echo canceller module. * All other XPDs are now of type 'telephony_device'. Only a telephony device XPD provides a span to register. * The EC module will typically show up as XPD-40 and will always show up as Unregistered in 'dahdi_hardware -v' Signed-off-by: Oron Peled <oron.peled@xorcom.com> Signed-off-by: Tzafrir Cohen <tzafrir.cohen@xorcom.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9993 a0bf4364-ded3-4de4-8d8a-66a801d63aff
