SIP User's Manual
Description
Defines the automatic fallback of the clock.

[0] Manual (default)

[1] Auto Non-Revertive

[2] Auto Revertive
Selects the fallback clock source on which the device
synchronizes in the event of a clock failure.

[4] Network (default)

[8] H.110_A

[9] H.110_B

[10] NetReference1

[11] NetReference2
Defines the SC/MVIP/H.100/H.110.

[0] SlaveMode = Slave mode (another device
must supply the clock to the TDM bus) or Master
mode (the device is the clock source for the TDM
bus) or Secondary Master mode (for H100/H110
Bus only). (Default.)

[1] MasterMode = H110A Master in Master mode.

[2] SecondaryMasterMode = H.110B Master.
Determines the NetRef frequency (for both
generation and synchronization).

[0] 8 kHz (default)

[1] 1.544 MHz

[2] 2.048 MHz
Enables or disables the PSTN trunk Auto-Fallback
Clock feature.

[0] Disable (default) = Recovers the clock from
the E1/T1 line defined by the parameter
TDMBusLocalReference.

[1] Enable = Recovers the clock from any
connected synchronized slave E1/T1 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.
Notes:

For this parameter to take effect, a device reset is
required.

This parameter is relevant only if the parameter
TDMBusClockSource is set to 4.
