12 28-Channel Framer Registers
(continued)
Table 314. FRM_PMGR4, Performance Monitor Global Register 4 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 315. FRM_PMGR5, Performance Monitor Global Register 5
—
PMGR5 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 316. FRM_PMGR6, Performance Monitor Global Register 6 (R/W)
* P = 0x0 for the receive path, and P = 0x1 for the transmit path.
Table 317. 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.

FRM_SFSEST[15:0]
SF Severely Errored Second Threshold for All SF Format-
ted Channels.
Note:
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.
There is a separate threshold for ESF and SF because
of the bit error provisioning in ESF (F
t
or F
s
).

FRM_DCT[15:0]
DS1 Excessive CRC Threshold
—
Default 320.
This register
sets the one second CRC threshold at which an excessive CRC
error condition is reported and the one second CRC threshold at
which a reframe may be forced.
