Tag-out control lines

This field displays a two-digit, hexadecimal value that identifies the outbound tags that were active when an interface control check (IFCC) occurred.

The hexadecimal number represents the values of eight bits:

Bit Tag-In
0                       Operational
1                       Address
2                       Select/Hold
3                       Data streaming
4                       Service
5                       Data
6                       Suppress
7                       Command

For example, a tag-out value of 84 indicates that Operational Out and Data Out are both active.
