This read-only object packs several pieces of module capability data into one octet string: a 2-byte maximum multilink-PPP link count, a 1-byte compression type (sw(2) or hw(3)), and a 4-byte maximum compression rate in kbps, all encoded big-endian. Because it's a composite structured field rather than a simple scalar, a management application must parse the byte offsets itself to extract each sub-value, such as whether the module compresses in software or hardware. A management tool reading this object might decode a compression-type byte of 3 (hw) and a max-rate field of 2048, telling the admin the module can hardware-compress WAN links up to 2 Mbps.
