NV-700I Master/Slave setting failure or phone cable length is over the specification limit.
Solution:
3.1 Please make sure that the phone wire must be connected between NV-700I(Master) side and

3.2 Please check phone wire, we recommend use 24-26 gauge with twisted pair and without rust.
3.3 Please reinsert power when change cable length or link time over 3 minutes.
3.4 Or try to change band profile as 17a for getting long reach.
Note:
Phone wire must meet CAT 3 standard or above and twisted pair, otherwise will cause more cross
talk issue to reduce Line power driver.
