Parameter Description
configure voip >
interface e1-t1 >
clock-masterclock-
master
[ClockMaster]
■ [0] Recovered = (Default) Generate the clock according to
the Rx of the E1/T1 line.
■ [1] Generated = Generate the clock according to the
internal TDM bus.
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ The source of the internal TDM bus clock is determined by
the parameter TDMBusClockSource.
■ The parameter is applicable only to E1/T1 interfaces.
'Auto Clock Trunk Priority'
configure voip >
interface e1-t1|bri >
clock-priority clock-
priority
[AutoClockTrunkPriority]
Defines the trunk priority for auto-clock fallback (per trunk
parameter).
The valid range is 0 to 100, where 0 (default) is the highest
priority and 100 indicates that the device does not perform a
fallback to the trunk (typically, used to mark untrusted source
of clock).
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ Fallback is enabled when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
'Line Code'
configure voip >
interface e1-t1 >
line-code
[LineCode]
Selects B8ZS or AMI for T1 spans, and HDB3 or AMI for E1
spans.
■ [0] B8ZS = (Default) B8ZS line code (for T1 trunks only).
■ [1] AMI = AMI line code.
■ [2] HDB3 = HDB3 line code (for E1 trunks only).
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ The parameter is not configurable for BRI interfaces; the
device automatically uses the Modified Alternate Mark
Invert (MAMI) line code.
'Line Build Out Loss'
configure voip >
interface e1-t1 >
ilne-build-out-loss
[LineBuildOut.Loss]
Defines the line build out loss for the selected T1 trunk.
■ [0] 0 dB (default)
■ [1] -7.5 dB
■ [2] -15 dB
■ [3] -22.5 dB
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ The parameter is applicable only to T1 trunks.
