ATM Call Control
Are ATM signaling connections being setup to A500 Call Control?
1. Enter show switch circuittable on the A500 console. Screen 5-33 shows
the screen output.

■ The pp UBR virtual circuits between A500 ports A1.1 (PPN) and Self
(A500) and between A1.2 (EPN) and Self (A500) are ATM signaling
channels between the port network and the A500.
■ They are used to request connection setups and releases to other end
points such as another port network.
■ These are established by each TN230X when it comes up, independent of
DEFINITY Call Processing.
■ Other UBR virtual circuits may exist between A500 ports that are not
associated with DEFINITY port networks and may be signaling channels
for other applications (for example, data network traffic).
CaPro Layer
Are control channels being established from the PPN to the EPN?
Diagnostics
■ Do you get a dial tone on a set on the port network in question?
■ Can you ring a set on the EPN dialing from the PPN and vice versa?
