Draft 5 of PN-3-4350.110 (Contribution TR41.3.5-01-11-036) allows the send and receive loudness ratings (SLR and RLR) to change by 7 dB when a parallel set goes off-hook or when a multi-line set is used in the conference mode. This contribution proposes increasing the allowed change to 8 dB.
In Contribution TR41.3.5-99-11-023, the current author proposed requirements that would allow the TOLR and ROLR levels of a telephone to change by up to 7 dB when used with a parallel set off-hook. The same criteria was also recommended for the conference mode performance of multi-line terminals. These proposals have been incorporated into Contribution TR41.3.5-01-11-036 (Draft 5 of PN-3-4350.110) as the allowed changes in SLR and RLR levels.
As the successor to Lucent Technologies Consumer Products, VTech Advanced American Telephones would like to exercise its prerogative to modify the contents of its original contribution as a result of further study. Our experience shows the 7 dB limit to be marginal in some cases, and we would like to propose the allowed change in SLR and RLR levels be increased to 8 dB.
Change “7 dB” to “8 dB” in the following four clauses of PN-3-4350.110:
188.8.131.52 (SLR) Parallel Set Off-Hook Requirement
184.108.40.206 (SLR) Conference Mode Requirement
220.127.116.11 (RLR) Parallel Set Off-Hook Requirement
18.104.22.168 (SLR) Conference Mode Requirement
