Table 71 - UDT VCI for Port p (one per port)
Table 69 - UTOPIA Service Enable Register
Table 70 - UTOPIA Incoming Cell Counter
Table 68 - UTOPIA Status Register
If set, this status bit indicates that the UTOPIA interface has received 2
by the UTOPIA Incoming Cell Counter at 4016h.
If set, this status bit indicates that the UTOPIA interface has received 2
containing parity errors, as counted by the UTOPIA Parity Mismatches Register at 400Eh.
Always reads “0000_0000_0000_00”.
When set, a ‘1’ on CELL_CNT_ROLL_STATUS will cause the UTOPIA_SRV bit to be set
in the Main Status Register at 0002h.
When set, a ‘1’ on PARITY_ROLL_STATUS will cause the UTOPIA_SRV bit to be set in
the Main Status Register at 0002h.
Always reads “0000_0000_0000_00”.
Counter indicating the number of cells received by the UTOPIA interface. If this counter
rolls over, the CELL_CNT_ROLL_STATUS status bit in the UTOPIA Status Register at
4012h will be set.
Note: This counter counts the number of SOC signals detected at the incoming UTOPIA
interface. Therefore, both “good” and errored cells are counted.
UDT VCI for TDM port p.
The VCI value of the incoming cell is compared to this value to determine if the cell is
destined for port p.
