1.1 T1 Loop Applications
NOTE
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The “a” represents the Total Access 3000 parameter
and the “b” represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed “28/22.”
