4.3 Connecting Common Signal Ground (Optionally)
The AST710 supports connectivity of one or more VoDSL ports to
a P(A)BX using Ground start initialization instead of the default
Loop start condition. For proper operation these VoDSL ports must
be configured for Ground start.
See section 15.2 for more information.
Moreover, both
AST710 and P(A)BX must share the same
common signal ground. Therefor, the AST710 features a Sig Gnd
port allowing to interconnect the AST710 and Ground start
P(A)BX(s).
Proceed as follows:
1. Plug the included green ground cable into the Sig Gnd port
located at the back panel of the AST710 .
Note : Do not open the AST710 box for connecting a common signal
ground to any of AST710 's internal parts !
2. Connect the other end of the ground cable to the common
signal ground connector of the P(A)BX.
Connecting Common Signal Ground
Never open the AST710 box for connecting a common signal
ground cable to any of AST710 's internal parts. None of its
internal parts are userservicable or userreplaceable.
Failure to do so could result in damage to equipment and could
cause bodily harm or loss of life.
Ground start operation
Failure to interconnect the AST710 and P(A)BX in order to share a
common signal ground for Ground start condition will result in
non functioning of connected P(A)BX(S) and/or telephony devices.
