: Cyclic redundancy check bits.
Spare bits for international use. Access to received information via bits
RSP.RS13 and RSP.RS15. Transmission is enabled via bits XSP.XS13 and
XSP.XS15. Additionally, automatic transmission for submultiframe error
indication is selectable.
Spare bits for national use. Additionally, Sa bit access via registers
RSA4 … 8 and XSA4 … 8 is provided. HDLC-signaling in bits Sa4- Sa8 is
selectable.
Remote alarm indication. Additionally, automatic transmission of the A-bit is
selectable.
