This read-write INTEGER (10..840 seconds) specifies, per its source description, how long an ESCON station waits for the host to respond to an attention signal before the station initiates a channel disconnect, with changes taking effect only the next time the station re-establishes communication with the host. Admins raise this value for a host known to be slow to respond to attention signals under heavy load, to avoid the station prematurely disconnecting a still-viable session. For example, increasing this from a shorter default toward the 840-second maximum would give a busy host more time to acknowledge before the station gives up and disconnects.
