12 28-Channel Framer Registers
(continued)
Table 328. FRM_PMGR6, Performance Monitor Global Register 6 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 329. FRM_PMGR7, Performance Monitor Global Register 7 (R/W)
These bits enable the errored events used to determine errored and severely errored seconds in the DS1 modes.
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 330. FRM_PMGR8, Performance Monitor Global Register 8 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 331. FRM_PMGR9, Performance Monitor Global Register 9 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.

FRM_ESFSEST[15:0]
ESF Severely Errored Second Threshold for All ESF
Formatted Channels.
A bursty errored second will be
recorded if the number of events is greater than the errored
second threshold but less than the severely errored second
threshold.
