tdmaCsV42RxN401FrameSize
tdma Cs V42 Rx N401 Frame Size
This attribute specifies the maximum number of octets that can be carried in the information field of an Information (I) frame, Exchange Identification (XID) frame, and a Unnumbered Information (UI) frame from the remote entity to the IWF. The default value is 128 octets, and no XID negotiations are required for rxN401FrameSize. If the value set for rxN401FrameSize is other than 128, XID frames are exchanged to negotiate a value. The value provided for rxN401FrameSize sets up the bounds during XID negotiations. The IWF performs XID negotiations with this value as a minimum or maximum value. If a value greater than 128 is specified, then the IWF attempts to negotiate for a value between 128 (as a minimum) and the given value (as a maximum). If a value less than 128 value is specified, then the IWF attempts to negotiate for a value between the given value (as a minimum) and 128 (as a maximum). Any value can be specified as long as it is within the provisionable limits. However, a value equal to or close to the default is recommended. Changes to this attribute do not affect existing calls.
