mscModVcsCallSetupTimer 1.3.6.1.4.1.562.36.2.1.16.2.13.1.3

This attribute specifies the Vc callSetupTimer in units of 1 second ticks. This timer specifies how long the Vc will wait, after sending a subnet Call Request packet into the network, for a response from the remote end of the Vc (in the form of a subnet Raccept packet). If, after sending a subnet Call packet into the network, a response is not received within this time period, the Vc will time out, clearing the call in the assumption that the remote end is unreachable. This timer must be long enough to take into account the time required for routing the subnet Call Request through the Source Call Routing and the Destination Call Routing systems in order to be delivered to the final destination.
