■The pp UBR virtual c ircuits between A500 ports A1.1 ( PPN) and Self
(A500) and between A1.2 (EPN ) and Self (A500) are ATM signaling
channels between the por t network and the A500.
■They are used to request connection se tups and releases to other end
points such as another por t network.
■These are established by each TN230X when it comes up , independent of
DEFINITY Call Processing.
■Other UBR virtual circuits may exist be tween A500 ports that are not
associated with DEFINITY port networks and may be sig naling channels
for other applications (for example, data network traffic).

Are control channels being established from the PPN to the EPN?
Diagnostics
■Do you get a dial tone on a set on the p ort network in question?
■Can you ring a set on the EPN dialing from the PPN and vice versa?
1. Enter list sys-link on the D EFINITY SAT. Figure 1-58 shows the screen
