List of Timer numbers¶
- Table of contents
- List of Timer numbers
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).
There are also numerous timer configurations in Osmocom predating introduction of T and X timers, not listed here.
