d) Landline (optional)
As an option, the WPS-2900 may be remotely controlled by either landline or RF link. Both
methods communicate via DTMF protocol. Remote control may be one-way or two-way.
The one-way option simply controls the WPS-2900, while the two-way option controls the
WPS-2900 and reports WPS-2900 status back to a central control point.
