2.2 Message Syntax

All multiple-byte fields within a message MUST be marshaled in little-endian byte order, unless otherwise specified. This protocol references commonly used data types as defined in [MS-DTYP].

Version 2 MCS Encoding Rules (defined in [T125] section 9) are used when encoding MCS structures defined in [T125]. The MCS Send Data Request ([T125] section 11.32) and MCS Send Data Indication ([T125] section 11.33) structures MUST be restricted to 16,383 or fewer bytes in length to avoid implementing ASN.1 Packed Encoding Rules (PER) extended size determinant encoding ([ITUX691] section 10.9.3, excluding 10.9.3.8).
