APPENDIX MC (Draft 1 - participants to verify their voting positions)

REQUIREMENTS FOR METER COMMUNICATIONS IN DIRECT ACCESS

July 29, 1998

VOTING RESULTS:   

Because some issues were passed without a unanimous agreement among PSWG participants, each of the issues adopted as requirements in this Appendix MC will have a table listing entities along with their voting positions.  Since some of the entities were sometimes absent from the PSWG Plenary meetings, the tables showing the voting results will show that these entities voted on some issues but not the others.

I.	TABLE OF STANDARDS
Following are tables of meter communications standards of which only ANSI C12.19 Standard is required for direct access implementation.

I.1.	Definitions of Terms used in Table I.2-1:
 
A meter type: A meter type that includes all parts, components and circuit boards, functioning as a unit.  A meter type includes all communication technologies and any additional functions utilized by that meter type and operated as a unit.  In a situation where a meter can work with multiple technologies or functions, but can only operate separately and individually with a single communication technology or function, the combination of the meter and one communication technology or function shall be considered as a different meter type from the combination of that meter and another communication technology or function.  For example, meter brand “X” with a phone modem attached is a different type from the same meter brand “X” with a radio modem attached.

(3)  New meter types: The meter types that satisfy CPUC requirements described in the CPUC Decision D.98-12-048 or the new requirements to be recommended by the PSWG and approved by the CPUC.  These meter types can be a new meter design or an existing meter which has undergone a significant design change.  A significant design change includes installation of an additional circuit board with new meter function(s) or  consolidation of two or more circuit boards.
Conforming meter type: The meter type that complies with C12.19 Standard.
Non-conforming (NC) meter type: The meter type that does not comply with C12.19 Standard.

(4)  Previously-approved NC meter types: The meter types that satisfy CPUC requirements described in the CPUC Decision D.98-12-048 and are currently being installed in California, but do not comply with C12.19 Standard.  

(5) In-inventory meter products: The meter products that have been purchased and stored in inventory, but not yet installed for direct access service in California.  This does not include used, re-worked or recycled meters.  

(6) In-service meter products: The meter products that have been approved and are currently in service for Direct Access. 

Used meter products: The meter products that are removed from service.

(7) Re-worked meter products: The used meter products that are repaired, rebuilt, or refurbished.  These do not include recycled or retrofitted meter products.  

(8) Recycled meter products: The used meter products that are cleaned, tested for accuracy and good operating condition, and returned to inventory. 
Retrofitted meter products: The in-inventory or used meter products that are retrofitted with electronic modules.

I.2.	Standard Required for Meter Products Used in Direct Access: ANSI C12.19-1998
Table I.2-1 shows the ballot result to accept Table I.2-2 as a requirement of ANSI C12.19 application, and Table I.2-2 lists only ANSI C12.19 Standard and specific requirements on how ANSI C12.19 applies on various meter products.  This ballot reflects that there is not 100% agreement on the issue.

Table I.2-2: Requirements for Application of ANSI C12.19 Standard on all communication technologies except as noted.   
Applicable for DA?	Required in  D97-12-048 	Staging Plan
(Effective date varies by meter products as defined in Section I above)	

(1)	

(2)	New meter types must conform 

(3)	Meter products of previously-approved NC
meter types may be purchased 
(4)	In-inventory  NC meter products may be installed

(5)	In-service NC meter products will be removed after
(6)	Re-worked 
NC meter products must comply 

(7)	Recycled NC meter products may be installed 
(8)	

Yes	

No	

After 3/20/00(a)   

	

Throughout the commercial life of the product.  No effective date for ANSI C12.19 compliance

No effective date for ANSI C12.19 compliance

No effective date for ANSI C12.19 compliance

	

No effective date for ANSI C12.19 compliance

	

No effective date for ANSI C12.19 compliance

(a)  2 years from C12.19 Standard publication date.	

As summary,  new meter types used in Direct Access shall comply with ANSI C12.19 Standard regardless of communication technology used by the meter products.

I.3.	Standards Not Required for Meter Products Used in Direct Access
Table I.3-1 shows the ballot result to accept Table I.3-2 which lists two standards: ANSI C12.21 and ANSI C12.22 Standards which shall not be required for meter products used in Direct Access.  This ballot reflects 100% agreement.

Table I.3-1: List of Communications Standards Not Required in Direct Access   
Standards	Applicable for DA?	Required in CPUC’s D97-12-048 	Required?	Effective date	Comments	
ANSI C12.21, Protocol Specification for Telephone Modem (not yet approved by ANSI)

Yes	

No	

No	

Not Applicable	
Applied to telephone modem only.	
ANSI C12.22, Meter Interface to Network Protocol Gateway (not yet approved by ANSI)

Yes	

No	

No	

Not Applicable

Applied to network only.	

These ANSI standards are under development and discussions for adoption.  Therefore, these standards will not be required in Direct Access.

II.	KYZ PULSE OUTPUTS

Meter products are not required to have pulse outputs.  However, if a meter product has external pulse outputs, the pulse output shall be KYZ pulses as specified in ANSI C12.1-1995 Standard (Code for Electricity Metering).  

Below is Table II-1 showing the voting results of 100% agreement on this requirement:

III.	BACK-UP METER READ

Meter products shall display the total kWH energy consumption as a minimum.  As meter products currently used in the market, it is sufficient to equip mechanical dial on electromechanical meters and digital kWH display on solid state meters.  Additionally, a meter product must have a physical communication interface to enable on-site interrogation of all stored meter data. 

Below is Table III-1 showing the voting results and entities’ position on this requirement:
