This chapter shows examples of E1 ALS70D signaling that use the following call control elements:
Each example begins with a brief explanation of the call, followed by a graphic representation of the call flow. These diagrams illustrate system processing and information flow between the VCO and the host, and between the VCO and the connected equipment. The direction of the information flow is indicated by arrows under the message data.
Example #1 illustrates a simple DTMF digit collection process after an incoming seize on the SDS E1 ALS70D circuit at port address $00 A9. A default inpulse rule is executed to perform DTMF digit collection on this circuit.
The following actions are performed in this inpulse rule example:
This rule is shown below.
Inpulse Rule #5
Refer to the Cisco VCO/4K System Administrator's Guide for more information about specific DTMF inpulse rule tokens.
Figure 4-1 shows the process flow for the incoming call in Example #1.
Example #2 describes DTMF digit outpulsing on an E1 circuit at port address $00 89. This process involves both host command and outpulse rule processing. The host initiates the outpulsing using the Outgoing Port Control ($69) command, and specifies the outpulse rule to execute. Refer to the Cisco VCO/4K Standard Programming Reference and the Cisco VCO/4K Extended Programming Reference for the command description.
The outpulse rule performs the following actions:
This rule is shown below.
Outpulse Rule #4
Figure 4-2 shows the process flow for the outgoing call in Example #2.
