STEP CORRECTIVE ACTION
4 The factory default settings for the Ethernet port of the VES-1012 are:
Speed: Auto
Duplex: Auto
Flow control: On
Trunking: Disabled
If the VES-1012’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and
duplex mode when making a connection, thus requiring you to make sure that the settings of the WAN
switch Ethernet port are in the same order to connect.
6.5 Testing Wiring
Systematically test wiring using a functioning telephone to determine if there is a wiring problem. If the
connection is good the telephone will return a dial tone. Letters in the figure shown next indicate the systematic
tests to be done. Suppose you’re using installation scenario “B” as shown in section
3.4.2 . The logic for other
scenarios should be similar.
A. Test A determines if there is a wiring problem between the CO and MDF 1.
B. Test B determines if there is a wiring problem between the CO Telco port on the VES-1012 and MDF 2.
C. Test C determines if there is a wiring problem between the USER Telco port on the VES-1012 and MDF 3.
D. Test D determines if there is a building-wiring problem between the subscriber’s wall jack and MDF 3.
