Per-VC Transmitted Cell Counter.
Within each VC’s UDT Reassembly Control Structure, there is a bit (V = VC Arrival) which is set each time
that a cell arrives on the VC. CPU monitoring of this bit can be used to provide per-VC timeout monitoring.
In addition to the counters themselves, if one of the following per-VC counters rolls over and the
corresponding service enable bit for the counter is set, a status field indicates the number of the TDM port
associated with the last UDT Reassembly Control Structure to generate a serviceable event.
Overall UDT Cell Counter
Within each VC’s SDT Reassembly Control Structure, there is a bit (V = VC Arrival) which is set each time
that a cell arrives on the VC. CPU monitoring of this bit can be used to provide per-VC timeout monitoring.
In addition to the counters themselves, if one of the following per-VC counters rolls over and the
corresponding service enable bit for the counter is set, a status field indicates the address in internal
memory of the last SDT Reassembly Control Structure to generate a serviceable event.
Overall SDT Cell Counter
• As well, there is a late VC status bit and a cut VC status bit for each port (and therefore VC). These bits are set when
