This section defines the TLVs required in a IUP DATA ICB to compose each message. TLVs may appear in any order within the IUP DATA ICB. If a TLV is not included and is required for the underlying PNO-ISC IUP Message a default value will be supplied from the appropriate configuration byte. Therefore, many messages can be generated from the configuration data area by only encoding a message containing the H0H1 TLV, since this uniquely identifies the message to be sent. However, several messages require additional TLVs to uniquely identify the message (for example, ACI and ASUI).

Least Significant Bit

Most Significant Bit

A bit framing standard for traditional time-division multiplexing, which standard describes user channels multiplexed onto a trunk that has been segmented (framed) into 24 bytes of 8 bits each. Note: The multiplexing function is performed in the D-4 framing structure by interleaving bits of consecutive bytes as they are presented from individual circuits into each D-4 frame.
