ABSTRACT:
The object of this invention is to provide an improved connection between a TTY keypad and an emergency call box. This is accomplished by lengthening and re-routing the multi-conductor ribbon cable that connects the TTY to the call box. Thus relieving the stress on the cable. This prevents the cable from cracking from fatigue and rendering the TTY box useless.
