 //		Olt Random Challenge Table
+//			This attribute specifies the random challenge OLT_challenge issued by the OLT during
+//			authentication step 1. It is structured as a table, with each entry being 17 bytes. The first
+//			byte is the table row number, starting at 1, and the remaining 16 bytes are the contents of the
+//			entry. OLT_challenge is the concatenation of all 16-byte content fields. In normal use, the OLT
+//			will write all the entries in the table, and then trigger the ONU's processing of the entire
+//			table using the OLT challenge status attribute. The table size is known by the maximum index set
+//			by the OLT. The OLT can clear the table with a set operation to row 0. (R, W) (mandatory) (17 *

+//			Upon ONU activation, the ONU sets the attribute to the initial value. When the ONU
+//			authentication status has the value 3, encryption keys exchanged in the TC layer will be
+//			encrypted using the master session key (ITUT G.984 systems) or the key encryption key (KEK,

 //		Master Session Key Name
+//			Following successful authentication, this register contains the "name," or the hash signature,

+//			3141 5926 5358 9793)).
+//
+//			If the selected hash function generates more than 128 bits, the result is truncated to the
+//			leftmost (most significant) 128 bits.
+//
 //			Upon the invalidation of a master session key (e.g., due to an ONU reset or deactivation, or due
 //			to an ONU-local decision that the master session key has expired), the ONU sets the master
 //			session key name to all zeros. (R) (mandatory) (16 bytes)

+//			The other two bits are reserved.
+//
+//			Row identifier (1 byte): The two MSBs of this field are the key index, which appears in the
+//			header of encrypted multicast GEM frames. Key index 0 always indicates cleartext, and should
+//			therefore not appear in the identifier. The four LSBs identify the key fragment number, starting
+//			with 0. The other two bits are reserved.
+//
+//			Key fragment (16 bytes): This field contains the specified fragment of the key (encrypted with
+//			AES-ECB using the KEK).

 //			(R, W) (optional) (18N bytes)
 //
+//			This attribute is defined only in ITU-T G.987 systems. It contains the broadcast key generated
+//			by the OLT. It is a table, each of whose rows is structured as follows.
+//

+//			set action. They always read back as 0 under the get next action.

+//
+//			01	Clear the specified row.
