Timer T2 | Used at SS, wait for broadcast ranging timeout | Max. value is 5*ranging interval |
Timer T3 | ranging response(RNG RSP) reception timeout following the transmission of a ranging request | Default and max. value is 200ms |
Timer T4 | Used at SS, Wait for unicast ranging opportunity. If the pending until complete field was used earlier by this SS, then the value of that field shall be added to this interval | Min. is 30 s, max. is 35 sec |
Timer T5 | Used at BS, wait for uplink channel change response | Max. value is 2 s |
Timer T6 | Used at SS, wait for registration response | Max. value is 3s |
Timer T7 | Used at SS/BS, wait for DSA/DSC/DSD response timeout | Max. value is 1s |
Timer T8 | Used at SS/BS, wait for DSA/DSC acknowledge timeout | Max. value is 300ms |
Timer T9 | Used at BS, registration timeout, the time allowed between BS sending a RNG RSP(success) to an SS, and receiving a SBC-REQ from that same SS | Min. and default. value is 300ms |
Timer T10 | Used at SS/BS, wait for transaction end timeout | Max. value is 3s |
Timer T12 | Used at SS, wait for UCD descriptor | Max. value is 5*UCD interval |
Timer T13 | Used at BS, time allowed for an SS following receipt of a REG RSP message to send a TFTP-CPLT message to the BS | Min. and default value is 15 min. |
Timer T14 | Used at SS, wait for DSX-RVD timeout | max. value is 200ms |
Timer T15 | Used at BS, wait for MCA-RSP message | Min. and default value is 20ms |
wimax Timer T16 | Used at SS, wait for bandwidth request grant | Min. is 10ms, Max. value is QoS dependent |
Timer T17 | Used at BS, time allowed for SS to complete SS authorization and key exchange | Min. is 5 min and default value is 5 min. |
Timer T18 | Used at SS, wait for SBC-RSP timeout | Default is 50ms and Max. is less than T9 |
Timer T19 | Used at SS, time DL channel remains unstable | |
Timer T20 | Used at SS, time the SS searches for preambles on a given channel. | Min. value is equivalent to MAC frames |
Timer T21 | Used at SS, time the SS searches for DLMAP on a given channel | Max. value is 10s |
Timer T22 | Used at SS/BS, wait for ARQ reset | Max. value is 0.5s |
Timer T23 | Used in mesh node system, network entry, detect network | Min. value is 1sec |
Timer T24 | Used in mesh node, network entry, accumulate MSH-NCFG messages | Default value is 120s |
Timer T25 | Used in mesh node, network entry, wait for MSH-NENT/MSH-NCFG | default value is 1s |
Timer T26 | used at SS, wait for TFTP-RSP | Min.=10ms, Default=200ms,Max.=200ms |
T27 as Idle timer | Used at BS, Max. time between unicast grants to SS when BS believes SS uplink transmission quality is good enough | Min. value is equal to SS Ranging Response processing time |
T27 as active timer | Used at BS, max. time between unicast grants to SS when BS believes SS uplink transmission quality is not good enough. | Min. value is equal to SS Ranging Response processing time |
