DCCA refers to this as the Tx Timer. Typically, this should be configured to a value smaller than the
response-timeout value of Diameter Endpoint Configuration Mode. That value is typically too large for
DCCA's purposes.
If DCCA gets a “no available routes” error before pending-timeout expires, then DCCA tries to send to the
secondary host (if one has been configured). If DCCA gets no response and pending-timeout expires, then
DCCA either tries the secondary host or gives up. This can now be managed using the
response-timeout value of Diameter Endpoint Configuration Mode. That value is typically too large for
DCCA's purposes.

The routing (i.e., returning a good response, no response or an error response such as "no available routes") is
controlled by Diameter Endpoint Configuration Mode. That uses a watchdog timer (called Tw Timer) to
attempt a different route to a host. Multiple routes could be attempted. If there's no response before the
endpoint's configured response-timeout expires, then "no available routes" is the routing result. The routing
logic remembers the status of routes, so it can return "no available routes" immediately, without using any
timers.
The default case will disable DCCA resending message at Tx (pending-timeout). So messages are retried only
at Tw (device watchdog timeout) by diabase or at response-timeout by DCCA.
