In our ongoing efforts to create the most efficient means of disseminating market data, CME Group will be implementing changes to the current ITC 2.1 Channels on the Market Data Platform (MDP) for CME Globex ^® data. These changes will only impact ITC channels for Globex market data and will be in parallel production beginning October 14, 2007.  Currently, the channel descriptions are as follows:

     Channel 4 – CME Globex Futures (Top of Book)

     Channel 5 – CME Globex Options (Top of Book)

     Channel 6 – CME Globex Spreads (Top of Book)

As of the start of trading Sunday October 14, 2007, the following channels will be added to the production environment in a more granular fashion similar to the current RLC channels:

     Channel 200 - CME Globex Equity Futures (Top of Book)

     Channel 201– CME Globex Equity Options (Top of Book)

     Channel 202– CME Globex Interest Rate Futures (Top of Book)

     Channel 203– CME Globex Interest Rate Options (Top of Book)

     Channel 204– CME Globex FX Futures (Top of Book)

     Channel 205– CME Globex FX Options (Top of Book)

     Channel 206– CME Globex Commodity, Industrials and TRKRS Futures (Top of Book)

     Channel 207– CME Globex Commodity, Industrials and TRKRS Options (Top of Book)

(We will provide you with a link to cme.com for IP addresses and port numbers within the next week or so.)                              

The existing ITC channels will be decommissioned on December 01, 2007 which will allow distributors time to parallel test prior to switching to the new channels.

Testing of these changes will be made available in the New Release environment beginning September 19, 2007 and in Certification on October 16, 2007.
