Each multislot class identifies the following:

* the maximum number of Timeslots that can be allocated on uplink
* the maximum number of Timeslots that can be allocated on downlink
* the total number of timeslots which can be allocated by the network to the mobile
* the time needed for the mobile phone to perform adjacent cell signal level measurement and get ready to transmit
* the time needed for the MS to get ready to transmit
* the time needed for the MS to perform adjacent cell signal level measurement and get ready to receive
* the time needed for the MS to get ready to receive.

The different multislot class specification is detailed in the Annex B of the 3GPP Technical Specification 45.002 (Multiplexing and multiple access on the radio path)
