Access Server Administrators’ Reference Guide 6 • DAX
Main Reference (daxClockMainRef)
The main reference parameter determines which WAN link will supply the clock for the system.
The following settings are available:
• none(0)—No clock selection. This would be used in conjunction with either a secondary or slave circuit.
• local-ref-1(1)—Use WAN Port 1 for primary timing. Generally the first WAN connection will be used as
the main reference.
• local-ref-2(2)—Use WAN Port 2 for primary timing. Generally the second WAN connection will be used as
the fallback reference (see “Fallback Reference (daxClockFallbackRef )”).
• local-ref-3(3)—Use WAN Port 3 for primary timing.
• local-ref-4(4)—Use WAN Port 4 for primary timing.
• local-ref-5(5)—Use WAN Port 5 for primary timing.
• local-ref-6(6)—Use WAN Port 6 for primary timing.
• local-ref-7(7)—Use WAN Port 7 for primary timing.
• local-ref-8(8)—Use WAN Port 8 for primary timing.
• netref-1(101)—Use to obtain system timing from a slave circuit.
• netref-2(102)—Use to obtain system timing from a slave circuit.
• oscillator(200)—Use internal free-run oscillator for the system clock
Fallback Reference (daxClockFallbackRef)
The fallback reference enables the configuration of a back-up clock reference should the main reference fail.
The following settings are available:
• none(0)—No clock selection. This would be used in conjunction with either a secondary or slave circuit.
• local-ref-1(1)—Use WAN Port 1 for secondary timing. Generally the first WAN connection will be used as
the main reference.
• local-ref-2(2)—Use WAN Port 2 for secondary timing. Generally the second WAN connection will be used
as the fallback reference. If there is only one WAN connection, then the fallback reference should be set to
oscillator.
• local-ref-3(3)—Use WAN Port 3 for secondary timing.
• local-ref-4(4)—Use WAN Port 4 for secondary timing.
• local-ref-5(5)—Use WAN Port 5 for secondary timing.
• local-ref-6(6)—Use WAN Port 6 for secondary timing.
• local-ref-7(7)—Use WAN Port 7 for secondary timing.
• local-ref-8(8)—Use WAN Port 8 for secondary timing.
• netref-1(101)—Use to obtain system timing from a slave circuit.
