Create CAS Stack

This article applies to: Product Version
Tmedia 2.9, 2.10, 3.0, 3.2

Once the necessary underlying CAS structures have been configured, you must create a new CAS R2 stack.

The TelcoBridges CAS stack features a scriptable register signaling engine that, in practice, allows the complete customization of communication processes using tones. More specifically, it is possible to modify the timing(s) of the tone exchanges, change the meaning(s) of each tone, and dynamically specify the sequence in which the tones are played. The CAS stack also provides integrated interoperability between variants and between other signaling types. For instance, the calling party category can be converted between variants and propagated to a SS7 call leg.

To create a CAS stack:

1- Click CAS in the navigation panel

3- Configure the new CAS stack:

  • Make sure the Enabled box is checked
  • Enter a name for the stack
  • Select a line service
  • Select a variant script
  • Click Create

4- Verify that the "CAS stack was successfully created" message is displayed.
