In line 1 we see our Q931 requesting (transmission: TX) a handshake procedure to setup an ISDN connection with certain parameters. Here the source is asking “can I connect to you?” Line 2 is the reception of the setup request to allow the “call to proceed.” In other words, the destination is responding with “I am not busy so you can connect to me.” Line 3 is our source actually connecting to the destination. Line 4-5 shows us the line coming up and connected with a number (555-1234). Line 6 is our destination telling the source “the line is established so you can bring up your interface and start sending information.” Line 7 shows us the source BRI is brought up and we can now transmit our data. Data Link Layer: Let’s start with our LAP-D negotiation (Q.921). This will negotiate the setting up of our SPID’s. Again, I used a BRI that was not connected, enabled the debug isdn q921, and then pinged the other BRI. (Don’t forget to turn off debug from the last step…it would be too confusing). kissane#debug isdn q921 ISDN Q921 packets debugging is on kissane#ping 192.168.1.1 Type escape sequence to abort.
