Learn DS0s on Boot Determines if the unit will attempt to discover active DS0s (after power-up,
Save and Restart). Active DS0s will then be assigned to the first associated
network service.
Values: Disable, Enable
Default: Disable
Learned DS0 Rate Specifies the rate at which each discovered DS0 will be set.
Values: As 56K/64K
Default: As 64K
NOTICE: The unit will search for active DS0s for a maximum of 7 seconds if
learning “As 64k” and for 30 seconds if learning “As 56K.”
Timing Sets the timing source to synchronize the unit’s internal timing generators. In
all cases, slips are controlled to occur on frame boundaries at the Network
ports when timing synchronization is lost. The options are as follows:
Network 1
“Function” parameter (on the Network 2 Config screen) in Slave mode
−
Internal, Network 1, Network 2, Serial 1, Serial 2
“Function” parameter (on the Network 2 Config screen) in Network mode
−
Internal, Network 1, Serial 1
Network 2
“Function” parameter in Slave mode
−
timing parameter is ignored in Slave
mode
“Function” parameter in Network mode
−
Internal, Network 2, Serial 2
Network (5130)
−
Internal, Network, Serial
Definitions of the timing sources are as follows:
Internal – The unit’s internal frequency standard (T1 1.544 Mbps ± 50 bps)
is used for all timing.
Network 1, Network 2, Network – Timing is derived from the Network port
recovered clock.
Serial 1, Serial 2, Serial – Timing is derived from the Serial port recovered
clock.
Mode Selects the network service type.
Values: Long Haul, Short Haul
Default: Long Haul
