Critical System Updates  

Alphanumeric Firm IDs Launch  
As previously announced, CME Group is introducing three-byte alphanumeric Firm IDs effective this Sunday, September 30, 2007. Currently, all Firm IDs are three-byte numerical only. Starting September 30, new customers will be assigned three-byte alphanumeric IDs.

The Firm ID is a sub-field of FIX tag 49, SenderCompID, and is required in iLink order entry messaging. Tag 49 is composed of the three-byte Session ID, three-byte Firm ID, and one-byte Fault Tolerance Indicator.

More information on this enhancement to the Firm ID and tag 49, SenderCompID, is available in the Enhanced Trade and Settlement Prices Client Impact Assessment. More information on tag 49, SenderCompID, is available in the iLink Message Specifications module of the iLink SDK.

The alphanumeric Firm ID 1P1 is currently available for customer testing in Certification.

ITC 2.1 Changes on the Market Data Platform  
Effective Sunday, October 14, 2007, CME Group will implement changes to the current ITC 2.1 channel schema for CME Globex data on the Market Data Platform. The following channels will be added to the Market Data Platform to provide more granular and scalable ITC 2.1 format market data:

• Channel 200 - CME Globex Equity Futures
• Channel 201 - CME Globex Equity Options
• Channel 202 - CME Globex Interest Rate Futures
• Channel 203 - CME Globex Interest Rate Options
• Channel 204 - CME Globex FX Futures
• Channel 205 - CME Globex FX Options
• Channel 206 - CME Globex Commodity, Industrials and TRKRS Futures
• Channel 207 - CME Globex Commodity, Industrials and TRKRS Options

These changes only impact the ITC 2.1 channels; there is no change to RLC-format channels.

The current channels 4, 5 and 6 for CME Globex ITC 2.1 market data will be maintained in parallel with the new channels in production until December 1, 2007.

• Channel 4 - CME Globex Futures
• Channel 5 - CME Globex Options
• Channel 6 - CME Globex Spreads

Please note: these ITC 2.1 channels, 4-6 and 200-207, disseminate Top of Book market data only.

These new channels are currently available for customer testing in the New Release environment, and in Certification on October 16. The channel definitions for New Release are now available at www.cme.com/certsdk.

Introducing Alphanumeric Host Order Numbers (HON)  
Effective September 15 in the New Release environment, CME Group introduced alphanumeric Host Order Numbers (HON) in FIX tag 37, OrderID, in all applicable iLink messaging. CME Group will force the following December 2007 futures to an alphanumeric HON in New Release:

• NYMEX Crude Oil - CLZ7
• E-mini S&P 500 ^® - ESZ7
• Eurodollar - GEZ7
• Euro FX - 6EZ7

Tag 37 is defined with a String format in the iLink Message Specifications module of the iLink Software Development Kit (SDK), so there is no field type change. Tag 37 is used to uniquely identify orders per contract, per trading session. Currently numeric only, tag 37 will use alphanumeric values to support the growth in trading and messaging volume.

Alphanumeric values for tag 37 will be launched in production in October.

Changes to Instrument Creation (MO) Replay Channels  
Effective Sunday, November 18, 2007, CME Group is introducing new Instrument Creation (MO) Replay channels on the Market Data Platform in production. With these new channels, every product RLC data channel (e.g., channel 7, Equity futures; channel 8, Equity options, etc.) will have a dedicated MO Replay channel so customers can listen only to the MO messages for which they receive market data.

The current MO Replay channels (channel 1 and 16) will be maintained in parallel for at least eight weeks before those channels are decommissioned.

Please note, these changes only affect the RLC-format channels. There are no changes to the ITC 2.1-format channels.

The new MO Replay channels will be available in New Release for customer testing next Thursday, October 4. The new MO replay channels will not be available in Certification until Wednesday, November 21. The channel definitions for New Release are now available at www.cme.com/certsdk.
