What's Annex A and Annex B? How can I know
if my router firmware is correct?
Annex A : ADSL over POTS ( analog phone line )
Annex B : ADSL over ISDN ( ISDN phone line
)
UR2 : For V2600, it is same as Annex B. UR2
is German standard.
The hardware of V2600 is different on Annex A and Annex
B model. You can get the firmware information as below.

Do not worry that you may use wrong firmware version.
V2600 will automatically check if the firmware is applied to the
hardware when you try to upgrade new firmware to router.
