User's Manual 1160 Document #: LTRT-27055
Mediant 1000B Gateway & E-SBC
Parameter Description
TDM Bus PSTN Auto FallBack Clock
configure voip > media tdm > pstn-bus-
auto-clock
[TDMBusPSTNAutoClockEnable]
Enables the PSTN trunk Auto-Fallback Clock feature.
 [0] Disable = (Default) Recovers the clock from the
trunk line defined by the parameter
TDMBusLocalReference.
 [1] Enable = Recovers the clock from any connected
synchronized slave trunk line. If this trunk loses its
synchronization, the device attempts to recover the
clock from the next trunk. Note that initially, the
device attempts to recover the clock from the trunk
defined by the parameter TDMBusLocalReference.
Note:
 For the parameter to take effect, a device reset is
required.
 The parameter is applicable only if the
TDMBusClockSource parameter is set to 4.
TDM Bus PSTN Auto Clock Reverting
configure voip > media tdm > pstn-bus-
auto-clock-reverting
[TDMBusPSTNAutoClockRevertingEnable]
Enables the PSTN trunk Auto-Fallback Reverting
feature. If enabled and a trunk returning to service has
an AutoClockTrunkPriority parameter value that is
higher than the priority of the local reference trunk (set in
the TDMBusLocalReference parameter), the local
reference reverts to the trunk with the higher priority that
has returned to service for the device's clock source.
 [0] Disable (default)
 [1] Enable
Note:
 For the parameter to take effect, a device reset is
required.
 The parameter is applicable only when the
TDMBusPSTNAutoClockEnable parameter is set to
1.
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: Fallback is enabled when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
