Enhanced Idle State Protocol Slotted Control

Last updated: June 18, 2009

This section is only applicable to the lab application.

When the Idle State Subtype is Enhanced (Subtype 1) , Enhanced Idle State Protocol Slotted Control determines whether the Slotted Mode Attribute Values is determined by the Access Network or by the Access Terminal.

• When the Enhanced Idle State Protocol Slotted Control is set to AN Specified ,
  • the test set specified the Slotted Mode attribute values, which will be configured for the session if successfully negotiated, and the current Slotted Mode Attribute Values in Configurable Attributes In Use window will be shown and affected by the Slotted Mode parameter settings.
  • Improper Slotted Mode attribute values will result in a rejection from the AT during session negotiation.
• When the Enhanced Idle State Protocol Slotted Control is set to AT Specified ,
  • the AT-requested Slotted Mode attribute values, if successfully negotiated, will be configured for the session.
  • the test set does not send any Configuration Request message for the Slotted Mode attribute. So changing the Slotted Mode parameter settings on the test set has no effect on the current session. The new setting is simply stored by the test set until the next session negotiation when it is set to AN Specified mode.
  • it is useful for some hybrid mode ATs that only function with certain Slotted Mode attribute values. You do not have to know the Slotted Mode attribute values specific for each AT prior to the proper setting, because the AT-requested Slotted Mode attribute values, will be configured for the session.
