“The "Network" attribute states, if the AG has the capability to reject incoming calls4. This attribute is not encoded as a data element sequence; it is simply an 8-bit unsigned integer. The information given in the “Network” attribute shall be the same as the information given in Bit 5 of the unsolicited result code +BRSF (see Section 4.24.3). An attribute value of 0x00 is translated to a bit value of 0; an attribute value of 0x01 is translated to a bit value of 1.”
