BLF LED Mode
BLF LED Mode provides four kinds of definition for the BLF key LED status. As there is no
hard line key on SIP-T48G IP phones, BLF LED mode configuration is only applicable to
SIP-T46G/T42G/T41P/T29G/T27P/T23P/T23G/T21(P) E2 IP phones. BLF LED mode is also
applicable to the expansion module EXP40 connected to SIP-T48G/T46G IP phones,
EXP39 connected to SIP-T29G and SIP-T27P IP phones. The following table lists the LED
statuses of the BLF key when BLF LED Mode is set to 0, 1, 2 or 3 respectively. The default
value of BLF LED mode is 0.
BLF LED mode feature is also applicable to BLF list key. For more information on BLF List
