Title II Technical Assistance Manual

II−7.3300 Seven-digit lines. Where a 911 line is not available and the public entity provides emergency services through a seven-digit number, it may provide two separate lines -- one for voice calls, and another for nonvoice calls -- rather than providing direct access for nonvoice calls to the line used for voice calls, provided that the services for nonvoice calls are as effective as those offered for voice calls in terms of time response and availability in hours. Also, the public entity must ensure that the nonvoice number is publicized as effectively as the voice number, and is displayed as prominently as the voice number wherever the emergency numbers are listed.
