<month year> CID 139 Comment I see no reason for requiring both CMS and MLR for SC devices. Since the CMS is the base rate for the SC PHY, it can be used for all coexistence and interoperability messages. This should allow devices to be built that guarantee coexistence while being cost effective for certain use cases. If necessary, require that al least one mode with data rate > 1 Gbps is also included. If the text in indicating that only CMS is mandatory does not also include MLR, then the specification will be consistent with necessary use cases. <author>, <company>
CID 139 Proposed Resolution
<month year> CID 139 Proposed Resolution On Page 67,Line 6 in clause 12.2 change: "There are two mandatory MCSs for all SC devices, The common mode signaling (CMS) and the mandatory low rate (MLR)." to "The common mode signaling (CMS) MSC shall be mandatory for all SC devices." On line 28 change: "The RS(255,239) and the shortened RS(33,17) block codes are mandatory, ..." "The RS(255,239) block code is mandatory, ...". Also, change any other place where both CMS and MLR are mandatory to just indicate CMS as mandatory. <author>, <company>
Rationale for Accepting CID 139
<month year> Rationale for Accepting CID 139 There are accepted requirements for low cost devices. Reducing number of required modes reduces implementation cost Clause indicates that only CMS is required to enable interoperability: “The role of CMS is to enable interoperability among different PHY modes. CMS may be used for both interference mitigation and data transmission purposes.” <author>, <company>
CID 139 Accept in Principle
<month year> CID 139 Accept in Principle On Page 67, Line 6 in clause 12.2 change: "There are two mandatory MCSs for all SC devices, The common mode signaling (CMS) and the mandatory low rate (MLR)." to "The common mode signaling (CMS) MSC shall be mandatory for all SC devices.” On line 28 change: "The RS(255,239) and the shortened RS(33,17) block codes are mandatory, ..." "The RS(255,239) block code is mandatory, ...” Add the following at the end of the first paragraph of clause 12.2: The mandatory low rate (MLR) or a low complexity mode employing OOK/DAMI shall be included in any PNC-capable SC DEV. <author>, <company>
