3. Symptom:
Line Link cannot be established.
Cause:
V700L 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 V700L(Master) side and
V700L(Slave) side when both are power on. V700L Master side will do link speed function
depending on phone wire length, therefore if V700L Master side can
’t detect Slave Side over
phone wire while both power on, this will cause the Link to fail.
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.
4. Question: What is VDSL2 technology? (Only reference)
Answer:
Very-high-speed digital subscriber line 2 (VDSL2) is an access technology that exploits the existing
infrastructure of copper wires that were originally deployed for traditional telephone service. It can
be deployed from central offices, from fiber-optic connected cabinets located near the customer
premises, or within buildings. It was defined in standard ITU-T G.993.2 finalized in 2005.
VDSL2 was the newest and most advanced standard of digital subscriber line (DSL) broadband
wireline communications. Designed to support the wide deployment of triple play services such as
voice, video, data, high definition television (HDTV) and interactive gaming, VDSL2 was intended to
enable operators and carriers to gradually, flexibly, and cost-efficiently upgrade existing xDSL
infrastructure.
