Hi,
The MIB pktcSigDevToneDbLevel defined in draft-11 has range
(-250..-30) with default value as -40dBm. Normal dial tone is at -13dB
(means -130dBm). Current default value is a too loud signal. I would
recommend to change the defailt to -120 along with the range to
(-250..-110)

pktcSigDevToneDbLevel OBJECT-TYPE
SYNTAX TenthdBm (-250..-30)
UNITS "dBm"=20
MAX-ACCESS read-only=20
STATUS current=20
DESCRIPTION=20
"This MIB Object contains the decibel level for each
analog signal (tone) that is locally generated =20
(versus in band supervisory tones) and sourced to =20
the a-b terminals (TE connection point). Each tone =20
in itself may consist of multiple frequencies as =20
defined by the MIB table 'pktcSigDevMultiFreqToneTable'.
=20
This MIB Object MUST reflect the desired level at =20
the Telco (POTS) a-b (T/R) terminals including the =20
affect of any MTA receiver gain (loss). This is required=20
so that locally generated tones are consistent with=20
remotely generated in band tones at the a-b terminals,=20
consistent with user expectations.
=20
This MIB Object must be set for each tone.
When tones are formed by combining multi-frequencies,
the level of each frequency shall be set so as to result
in the tone level specified in this object at the a-b
(T/R) terminals.
=20
The wide range of levels for this Object is required =20
to provide signal generator levels across the wide =20
range of gains (loss) - but does not imply the entire=20
range is to be achievable given the range of gains (loss)=20
in the MTA."
