LOCAL AND METROPOLITAN AREA NETWORKS—PART 16:

11.4 Common encodings

In the following subclauses, length is in bytes. Type fields and length fields are 1 byte in length.

11.4.1 SS Capabilities encoding

This value field describes the capabilities of a particular SS, i.e., implementation dependent limits on the particular features or number of features which the SS can support. It is composed from a number of encapsulated type/length/value fields. The encapsulated subtypes define the specific capabilities for the SS in question. Note that the subtype fields defined are only valid within the encapsulated capabilities configuration setting string.

11.4.1.1 Uplink CID support

This field shows the number of Uplink CIDs the SS can support. The minimum value is 3; an SS shall support a Basic CID, a Primary Management CID, a Secondary Management CID, and 0 or more Transport CIDs.
