For MP-2100/MP-2200 and for MP-104/204 from R2: This object represents 6 parameters, by 3 Octets : Busy Code-MSB nibble, - applicable only for Rx translation Idle Code- nibble, - applicable only for Rx translation D Bit Code- nibble, C Bit Code- nibble, B Bit Code- nibble, A Bit Code-LSB nibble. Each of Busy and Idle Code nibble will have the valid values: 0000 .. FFFF. Each of A,B,C,D Bit Code nibble represents: 0 hex = 0000 = 0 1 hex = 0001 = 1 2 hex = 0010 = A bit 3 hex = 0011 = B bit 4 hex = 0100 = C bit 5 hex = 0101 = D bit 6 hex = 0110 = A bit inverse 7 hex = 0111 = B bit inverse 8 hex = 1000 = C bit inverse 9 hex = 1001 = D bit inverse A-F hex - not used (invalid values) For MP-104/204 R1: This object represents 3 parameters, by 2 Octets : Bit 1 = Bit A - OFF Hook for Tx ; Ring for Rx (LSB) Bit 2 = Bit B - OFF Hook for Tx ; Ring for Rx Bit 3 = Bit C - OFF Hook for Tx ; Ring for Rx Bit 4 = Bit D - OFF Hook for Tx ; Ring for Rx Bit 5 = Bit A - ON Hook for Tx ; Idle for Rx Bit 6 = Bit B - ON Hook for Tx ; Idle for Rx Bit 7 = Bit C - ON Hook for Tx ; Idle for Rx Bit 8 = Bit D - ON Hook for Tx ; Idle for Rx Bit 9 = Bit A - OOS State for both Tx and Rx Bit 10 = Bit B - OOS State for both Tx and Rx Bit 11 = Bit C - OOS State for both Tx and Rx Bit 12 = Bit D - OOS State for both Tx and Rx Bit 13 = Spare (always 0) Bit 14 = Spare (always 0) Bit 15 = Spare (always 0) Bit 16 = Spare (always 0) (MSB) When the object is not applicable, the Octet String will have 0 bytes.
