11.20.2 ATM/PPP Related Performance Counters
All these performance counters are one second shadow counters: at the one second
boundary the contents of each performance counter is latched into its one second shadow
register, after which the performance counter is cleared. These one second shadow registers
will hold their value during the entire period between two subsequent one second boundaries.
The one second shadow registers are available for software read-only access.
All errored BIP and Block counters are dimensioned to cover the maximum count value
during a one second interval meaning they can never reach saturation.
The one second boundary is generated by the internal one second clock which is either
derived from the PHAST-12P system clock or from the external REFONESECCLK input lead.
The performance counters can be reset by writing 0x91 into the ResetCounters register.
The PHAST-12P supports the following ATM/PPP related performance counters:
• RS/section counters APS interface:
• MS/line counters per line interface:
• Pointer adjustment counters per high order path:
• POH counters per high order path:
• ATM demapping:
