Table 6-11. Observed Cause Codes
Cause
Code	Definition	Observed Cause
3	No route to destination	The ATM addresses administered in the ATM switch or
		in DEFINITY (display atm pnc) are incorrect.
31	Normal, unspecified	This is a normal return.
41	Temporary failure	This “try again later” cause code has been observed
		when the source of the problem is on another port (for
		example, a routing problem on another port that
		displays cause code 3).
47	Resources unavailable,	DEFINITY call volume is too high for the available
	unspecified	resources in the ATM network.
63	Service or option unavailable,	DEFINITY call volume is too high for the available
	unspecified	resources in the ATM network.

ATM call control

Are ATM signaling connections being setup to ATM switch Call Control?

The UBR virtual circuits between the ATM switch PPN port and ATM switch port and between the EPN port and ATM switch port are ATM signaling channels between the port network and the ATM switch. They are used to request connection setups and releases to other end points such as another port network. These are established by each TN2305/TN2306 when it comes up, independent of DEFINITY Call Processing.

Other UBR virtual circuits may exist between ATM switch ports that are not associated with DEFINITY port networks and may be signaling channels for other applications (for example, data network traffic).

Call processing (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?
