It's a deep quagmire...but it appears to me that the information (or at least instructions on how to measure volume) are contained in ANSI/EIA/TIA-470 and 579. (I don't have copies)
I know from charts that I've looked at the "Normal Conversation" is approx 60db

I know the docs say the 2216 is HAC compliant, but are the headsets/handsets the most current? or did they get swapped with older versions maybe? Just trying to hit on something that might help....



Here's some dry reading for you:



(Chart)
Figure 3: Decibel levels of common sounds.

60 dB Everyday conversation, ringing telephone.
70 dB Restaurant.
80 dB Heavy city traffic, alarm clock at 2 feet, factory noise, vacuum cleaner, garbage disposal.
90 dB Subway trains, motorcycle, workshop tools, lawn mower.
100 dB Chain saw, pneumatic drill.
110 dB Dance club.
120 dB Rock concert speaker sound, sandblasting, thunderclap.
130 dB Jet take off, gunfire.

Note : The actual (ROLR) Receive Objective Loudness Rating is a measument reference that I cannot find right at the moment - the following speaks to it:

TITLE 47--TELECOMMUNICATION

CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION (CONTINUED)

PART 68_CONNECTION OF TERMINAL EQUIPMENT TO THE TELEPHONE NETWORK--Table
of Contents

Subpart D_Conditions for Terminal Equipment Approval

Sec. 68.317 Hearing aid compatibility volume control: technical standards.

(a) An analog telephone complies with the Commission's volume
control requirements if the telephone is equipped with a receive volume
control that provides, through the receiver in the handset or headset of
the telephone, 12 dB of gain minimum and up to 18 dB of gain maximum,
when measured in terms of Receive Objective Loudness Rating (ROLR), as
defined in paragraph 4.1.2 of ANSI/EIA-470-A-1987 (Telephone Instruments
With Loop Signaling) . The 12 dB of gain minimum must be achieved
without significant clipping of the test signal. The telephone also
shall comply with the upper and lower limits for ROLR given in table 4.4
of ANSI/EIA-470-A-1987 when the receive volume control is set to its
normal unamplified level.

Note to paragraph(a):
Paragraph 4.1.2 of ANSI/EIA-470-A-1987 identifies several
characteristics related to the receive response of a telephone. It is
only the normal unamplified ROLR level and the change in ROLR as a
function of the volume control setting that are relevant to the
specification of volume control as required by this section.

(b) The ROLR of an analog telephone shall be determined over the
frequency range from 300 to 3300 HZ for short, average, and long loop
conditions represented by 0, 2.7, and 4.6 km of 26 AWG nonloaded cable,
respectively. The specified length of cable will be simulated by a
complex impedance. (See Figure A.) The input level to the cable
simulator shall be -10 dB with respect to 1 V open circuit from a 900
ohm source.
(c) A digital telephone complies with the Commission's volume
control requirements if the telephone is equipped with a receive volume
control that provides, through the receiver of the handset or headset of
the telephone, 12 dB of gain minimum and up to 18 dB of gain maximum,
when measured in terms of Receive Objective Loudness Rating (ROLR), as
defined in paragraph 4.3.2 of ANSI/EIA/TIA-579-1991 (Acoustic-To-Digital
and Digital-To-Acoustic Transmission Requirements for ISDN Terminals).
The 12 dB of gain minimum must be achieved without significant clipping
of the test signal. The telephone also shall comply with the limits on
the range for ROLR given in paragraph 4.3.2.2 of ANSI/EIA/TIA-579-1991
when the receive volume control is set to its normal unamplified level.
(d) The ROLR of a digital telephone shall be determined over the
frequency range from 300 to 3300 Hz using the method described in
paragraph 4.3.2.1 of ANSI/EIA/TIA-579-1991. No variation in loop
conditions is required for this measurement since the receive level of a
digital telephone is independent of loop length.
(e) The ROLR for either an analog or digital telephone shall first
be determined with the receive volume control at its normal unamplified
level. The minimum volume control setting shall be used for this
measurement unless the manufacturer identifies a different setting for
the nominal volume level. The ROLR shall then be determined with the
receive volume control at its maximum volume setting. Since ROLR is a
loudness rating value expressed in dB of loss, more positive values of
ROLR represent lower receive levels. Therefore, the ROLR value
determined for the maximum volume control setting should be subtracted
from that determined for the nominal volume control setting to determine
compliance with the gain requirement.
(f) The 18 dB of receive gain may be exceeded provided that the
amplified receive capability automatically resets to nominal gain when
the telephone is

caused to pass through a proper on-hook transition in order to minimize
the likelihood of damage to individuals with normal hearing.
(g) These incorporations by reference of paragraph 4.1.2 (including
table 4.4) of American National Standards Institute (ANSI) Standard
ANSI/EIA-470-A-1987 and paragraph 4.3.2 of ANSI/EIA/TIA-579-1991 were

I Would Suggest If The Higher Ups Want A Difinition, They Can Understand That You Contact Your Vendor. Actually It Sounding Like This Is Already In A Legal Thing, I Would Have The Lawyers Contact Nortel Direct Through Your Vendor

Forgot To Say I've Been In This One Before

Rachelle

Thanks for the good stuff. I have recommended that Nortel be contacted. This is beyond my office or my scope. I can find no physical cause or proof of the issues being reported. I can't duplicate. When on site, I jacked in to the calls when they said they were having a problem and the problem was the other person was on a cordless phone and outside or on a cell phone. I experienced not a single case of the telephony equipment failing or lacking. I don't know what more I can do.

Because the phone cant speak for itself (or can it?), it is obviously an easy target for blame. In my case, what I did was.. take all of the people complaining. Move them to a quiet area of the building (in my case, it was an underground vault) with no AC or heat.Remove all radios. No cordoroy pants (removes all 'thick-thighed' noises). Board up all windows and close the blinds. Remove all articles of clothing that could interfere with being able to listen to phone (no earrings). Have all users clean out there ears with Q-Tips at the beginning of each shift (mandatory)...and above all, tell everyone to STHU when someone else is on the phone. TGIF!

Good Luck.

Catalytic_Avatar

similar here but on an Avaya definity g3si... we have volume adjustment on the phones for that reason.. (pabx companies have obviously thought about this) but we found customer on mobile phones or cordless phones could be hard to hear, we also found that some fool (vendor rep probably a kid on vacation work) then set the default conversation boost system wide to +40db.. which is WAY to high on a system with a decent PSTN behind it. We had a LOT of feedback till we killed that off. Your vendor or Nortel themselves should be able to clear this up for you. gl with it
