You can change most of the trunk timers through your local TTY device
on your SL-1(?). Overlay 15 [Customer Data Block] allows you to set
both your EOD timer for non-DTMF trunks and your ODT timer for DTMF
trunks (``DIGITONE'' in NT nomenclature). Default settings are usually
sufficient for most applications, however, you must have extremely
fast CO trunks. Reducing the timer's values may indeed help your
situation, but take heed ... too much will raise `havoc' with the
people using the system. Try reducing EOD timer by 25% of the default,
and ODT timer by the same. Consult the NTP's for more information.
Reach me by one of the methods below if you wish to discuss in depth.
