STEP
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.

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.
