This controls whether the HMTS automatically changes the Forward ports frequency (hmtsFwdHmtsFrequency) when hmtsFwdXpndrFrequency is set. automatic - The HMTS automatically sets its transmitter to the newly commanded transponder frequency. The algorithm executed for this change is vender specific. manual - The HMTS requires the that its forward port transmitter frequency be explicitly set by a higher level manager. The HMTS shall respond with a bad value error if an attempt is made to set this object to an unsupported value. This object is non-volatile.
