It is a fixed value (as defined on 3GPP TS 44.006_V8), and it depends on the type of used channel: The N200 value for layer 2 link establishment and release is 5. In the state “timer recovery”, N200 is set to as below, 5 for use on SACCH; 23 for use on SDCCH; 34 for use on FACCH/full rate; (Note:1) 29 for use on FACCH/half rate. 48 for use on E-FACCH/full rate; Note 1 : All types of FACCH/Full rate except E-FACCH/F For SAPIs other than 0 or 3, the value of N200 is 5.
