VISM Release 3.0 allows you to configure provisional tone plans if the built-in tone plans do not meet
your application needs. Provisional tone plans are created by assigning new region/country, version, and
file names, and configuring the following call progress tones:

Loop Start, DID, and Delay Dial

The exchange side (FXO) of the loop start protocol is implemented with this release. VISM can accept
calls from, and terminate calls to, loop start PBXs. When a PBX sends a subscriber call to the gateway,
it sends the loop close signal through the CAS signaling channel. To hang up, it sends the loop-open
signal.
Direct inward dial enables a caller outside a company to call internal extensions without having to go
through an operator or an attendant. VISM has this ability—it outpulses the digit stream handed down
by the call agent.
Dial delay is an E&M signaling protocol similar to wink start. The originating VISM, on receiving a
seize (AB=11) from the PBX, responds by sending the delay-dial (AB=11) signal back to the PBX.
When the originating VISM is ready to collect the digits, it sends start-dial (AB=00) signal. This
operation is symmetric. So the terminating VISM, on seizing a trunk, should receive AB=11 (as an
acknowledgment that the trunk is operational). Subsequently when it receives the start signal (AB=00)
from the connected PBX, it should outpulse the digits. The rest of the operation is similar to wink-start.
