Carsten,

My responses

Q1: The number resources the FCC is meant to set aside for the ENUM

trial - will they cover all US geographic area codes or is that somehow

limited? If so, what will be the limits or restrictions?

The US trial committee participants are identifying the geographic areas (NPAs) and the amount of numbers they require to conduct their ENUM test cases. Since the FCC has not responded to the wavier request with any restrictions or limits, there are none that I am aware of at this time. Trial participants do not expect to have limits placed on them beyond what the USG terms and conditions called for – that all numbers to be used in the US ENUM trial must be allocated under wavier by the FCC.

Q2: In slide 5, 9 and 10 you mention the "Trial Participants Advisory

Committee (TPAC)", what roles will be involved when in the trial and

what documentation TPAC is meant to produce. I just wonder to what

extent the users - aka. number holders, aka. ENUM domain name

registrants - will be involved, as they seem to not be mentioned explicitly?

The trial MOU calls for trial participants to identify what role or roles they intend to play in the US trial. The ones that I outlined in my presentation are the options that a trail participant can choose from. Such as number holders are identified as End Users and ENUM Domain Name Registrants once they have been authenticated and verified. There are several parties that have indicated that they intend to be End Users for the trial.

Also the TPAC will produce reports on its trial activities on a monthly basis for the CC1 ENUM LLC. Initially these reports should contain the organizational plans (who is playing what role(s)) and test case development associated with the three phases of the trial. Once the trial starts, I expect that the monthly reports will contain the results of the tests that have been run during that month. Once the trial has ended, a final report that summarizes all activities and results will be complied for the LLC.
