Table 11: Impact of TLVs Received by 1600 Series IP Telephones on System Parameter Values (continued)

System

TLV

Impact

Parameter Name

Name

 

 

 

L2Q, L2QVLAN,

MED Network

L2Q - set to “2” (off) If T (the Tagged Flag) is set to

L2QAUD,

Policy TLV

0; set to “1” (on) if T is set to 1.

L2QSIG,

 

L2QVLAN - set to the VLAN ID in the TLV.

DSCPAUD,

 

L2QAUD and L2QSIG - set to the Layer 2 Priority

DSCPSIG

 

value in the TLV.

 

 

DSCPAUD and DSCPSIG - set to the DSCP value

 

 

in the TLV.

 

 

A check is made as to whether a reset is necessary

 

 

to obtain a new IP address due to a change in the

 

 

values of the parameters L2Q or L2QVLAN.

 

 

This TLV is ignored if:

 

 

the value of USE_DHCP is “0” and the value

 

 

of IPADD is not “0.0.0.0”, or

 

 

the Application Type is not 1 (Voice) and is

 

 

not 2 (Voice Signaling), or

 

 

the Unknown Policy Flag (U) is set to 1.

 

 

 

MCIPADD

Proprietary Call

MCIPADD will be set to this value if it has not

 

Server TLV

already been set.

TLSSRVR and

Proprietary File

TLSSRVR and HTTPSRVR will be set to this value

HTTPSRVR

Server TLV

if neither of them have already been set.

 

 

 

L2Q

Proprietary 802.1

The default L2Q is set to the value of this TLV. No

 

Q Framing

change is made to the current L2 tagging, but the

 

 

new default value is used on the next reboot. If TLV

 

 

= 1, L2Q set to "1" (On). If TLV = 2, L2Q set to "2"

 

 

(Off). If TLV = 3, L2Q set to "0" (Auto).

 

Proprietary - PoE

This proprietary TLV can initiate a power

 

Conservation TLV

conservation mode. The telephones that support

 

 

this will turn on/off the telephone backlight and the

 

 

backlight of an attached Button Module in response

 

 

to this TLV.

 

Extended

Power conservation mode will be enabled if the

 

Power-Via-MDI

received binary Power Source value is 10, and

 

 

power conservation mode will be disabled if the

 

 

received binary Power Source value is not 10.

 

 

Power conservation mode is enabled even if the

 

 

telephone is not powered over Ethernet because

 

 

the telephone sends information about the power

 

 

source that it is using in a TIA LLDP MED Extended

 

 

Power-Via-MDI TLV; it is assumed that the power

 

 

management system intends to conserve local

 

 

power as well.
