The HA-1 hybrid adaptor allows you to use your favorite broadcast hybrid with almost any telephone.old, new, single or multiple line, etc. Since the HA-1 hooks up through your telephone instrument's handset connector, no connection to the telephone line is needed. With the HA-1's front panel push buttons, connecting your hybrid is fast and easy.and the hybrid performance is the same as if hooked directly to the central office line.
