Corrigendum 2 to Recommendation ITU-T G.7710/Y.1701 (2007) corrects text in Amendment 1 to ITU-T G.7710/Y.1701 (2007), which updates the packet layer related specification of severely errored second (SES) in ITU-T G.7710/Y.1701 to align it with the SES definition in Recommendation ITU-T Y.1563.

While lost block count (LBC) was defined in clause 10.1.2 and included in the NPME input/output signal tables (Table 27 and Table 28), it was left out in the process description in clause 10.2.1. This corrigendum corrects the error by adding the missing 6 LBC terms to the process description.
