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
key, refer to BLF List on page 322.
