HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER

AND M13 MULTIPLEXER

PROPRIETARY AND CONFIDENTIAL

• path parity error (CPERR) events

• far end block error (FEBE) events

• excess zeros (EXZS)

• framing bit error (FERR) events

Due to the off-line nature of the DS3 and E3 Framers, PMON continues to

accumulate performance metrics even while the framer has declared OOF.

When an accumulation interval is signaled by a write to the PMON register

address space or to the Global PMON Update register, the PMON transfers the

current counter values into microprocessor accessible holding registers and

resets the counters to begin accumulating error events for the next interval. The

counters are reset in such a manner that error events occurring during the reset

period are not missed.

When counter data is transferred into the holding registers, an interrupt is

generated, providing the interrupt is enabled. If the holding registers have not

been read since the last interrupt, an overrun status bit is set. In addition, a

accumulation interval.

Whenever counter data is transferred into the holding registers, an interrupt is

generated, providing the interrupt is enabled. If the holding registers have not

been read since the last interrupt, an overrun status bit is set.

9.13 DS3 Transmitter (DS3-TRAN)

Three DS3 transmitters are instantiated. Each may be programmed to provide

framing for unchannelized data from TDATI[x] or the SBI bus, or framing for

multiplexed T1s or E1s (ITU-T Rec. G.747).

The DS3 Transmitter (DS3-TRAN) Block integrates circuitry required to insert the

overhead bits into a DS3 bit stream and produce a B3ZS-encoded signal. The

T3-TRAN is directly compatible with the M23 and C-bit parity DS3 formats.

Status signals such as far end receive failure (FERF), the alarm indication signal,

and the idle signal can be inserted when their transmission is enabled by internal

combination of LOS, OOF or RED, or AIS by the DS3-FRMR.
