h1. List of Timer numbers 

 {{toc}} {{>toc}} 

 Below is a list of timer numbers used in Osmocom programs. 
 Many are specified by 3GPP specifications, indicated by a T (like T3103). 
 There are also various Osmocom specific timers, indicated by an X (like X23).  

 h2. Timers specified by 3GPP 

 |_.Timer|_.Program|_.Purpose| 
 | T7 | [[OsmoBSC:]] | inter-BSC/MSC Handover outgoing, BSSMAP HO Required to HO Command timeout | 
 | T8 | [[OsmoBSC:]] | inter-BSC/MSC Handover outgoing, BSSMAP HO Command to final Clear timeout | 
 | T10 | [[OsmoBSC:]] | RR Assignment | 
 | T101 | [[OsmoBSC:]] | inter-BSC/MSC Handover incoming, BSSMAP HO Request to HO Accept | 
 | T3101 | [[OsmoBSC:]] | RR Immediate Assignment | 
 | T3103 | [[OsmoBSC:]] | Handover | 
 | T3105 | [[OsmoBSC:]] | Physical Information | 
 | T3107 | [[OsmoBSC:]] | (unused) | 
 | T3109 | [[OsmoBSC:]] | RSL SACCH deactivation | 
 | T3111 | [[OsmoBSC:]] | Wait time before RSL RF Channel Release | 
 | T3113 | [[OsmoBSC:]] | Paging | 
 | T3115 | [[OsmoBSC:]] | (unused) | 
 | T3117 | [[OsmoBSC:]] | (unused) | 
 | T3119 | [[OsmoBSC:]] | (unused) | 
 | T3122 | [[OsmoBSC:]] | Wait time after RR Immediate Assignment Reject | 
 | T3141 | [[OsmoBSC:]] | (unused) | 
 | T3212 | [[OsmoBSC:]] | Periodic Location Update timer, sent to MS (1 = 6 minutes) | 


 h2. Timers specific to Osmocom 

 |_.Timer|_.Program|_.Purpose| 
 |X1 | X1 | [[OsmoBTS:]] | Time after which osmo-bts exits if regular ramp down during shut down process does not finish (s) | 
 |X2 | X1 | [[OsmoBSC:]] | MGCP response timeout | 
 | X2 | [[OsmoBTS:]] | Time after which osmo-bts exits if requesting transceivers to stop during shut down process does not finish (s)| 
 | X1 | [[OsmoBSC:]] | MGCP response timeout | 
 | X2 | [[OsmoBSC:]] | RTP stream establishing timeout | 
 | X23002 | [[OsmoBSC:]] | Wait time for RSL Channel Activate ACK after sending RSL Channel Activate | 
 | X23005 | [[OsmoBSC:]] | Wait time for RSL IPA CRCX ACK after sending RSL IPA CRCX | 
 | X23006 | [[OsmoBSC:]] | Wait time for RSL IPA MDCX ACK after sending RSL IPA MDCX | 


 h3. Legacy timer numbers: specific to Osmocom, but still defined as T timers 

 |_.Legacy T timer|_.corresponding X timer|_.Software|_.Purpose| 
 |T2427001 | T2427001 | - | [[OsmoMGW:|libosmo-mgcp-client]] [[OsmoBSC:]] [[OsmoMSC:]] | timeout for MGCP response from MGW | 
 | T992427 | - | [[OsmoBSC:]] | MGCP timeout (2427 is the default MGCP port number) | 
 | T993111 | - | [[OsmoBSC:]] | Wait time after lchan was released in error (should be T3111 + 2s) | 
 | T993210 | - | [[OsmoBSC:]] | After L3 Complete, wait for MSC to confirm | 
 | T999 | - | [[OsmoBSC:]] | After Clear Request, wait for MSC to Clear Command (sanity) | 
 | T992427 | - | [[OsmoBSC:]] | MGCP timeout (2427 is the default MGCP port number) |
