I have a standard 16U-4FXO UC520 and i am getting a PRI line from AT&T. Is there some documentation for setting this up as well configuring the UC with PRI?
I believe the new IOS allows the system to recognize the VIC. When it is recognized, it will (should) appear.
Verified with engineering - this is a known issue. Can you use UC 520 Early Adopter Software Pack 7.1.3? This bundles IOS image 12.4(22)YB4 that has the fix. You can download it from https://supportforums.cisco.com/docs/DOC-9829.
The current version of CCA defaults the framing and linecode to ESF and B8ZS respectively. It provides you following configuration parameters:
Connection Type: Select T1
Channel Signaling: Select ISDN PRI
Switch Type: Check w/ your provider (most common is primary-ni)
Bearer Cap: Select Speech
PRI Group: Check with your provider on the number of channels enabled for your PRI. Note that on the Desktop form factor (8U and 16U UC 520), a maximum of 22 channels can be defined. The default T1 range is 1 time slot to 24 time slots; time slot 24 (the D-channel) is always included. The range of time slot 24 to time slot 24 is invalid.
Attached is a screen-shot for an E1, but the configuration of T1 should be fairly similar
Please note that CCA release 2.1 will be released later this week that has an extensive troubleshooting section that can be used to troubleshoot connectivity issue.
You should also look at this document.
It has a lot of good information on using CCA. It doesn't specifically have PRI information, but it has a good information about using CCA, using it with your dial plans, DID mapping etc.
You should be able to use CCA release 2.0.1 to configure the PRI and the associated dialplan. The GUI is fairly straight forward and has online help for guidance. Couple of things that you may need from your provider:
Framing - SF or ESF (ESF is most common)
Line Code - AMI or B8ZS (B8ZS is most common)
Number of channels on the PRI. Note that the 16-user UC 520 can support a maximum of 22 voice channels.
Let us know if you run into any issues.
