excessive zeros are reported by driving CVn high for one clock
cycle. If HDB3 or B8ZS is not selected, this pin indicates only
BPVs.
Note: During an RLOS condition the output remains active.

Receive Clock for Channel 1 to 8.
The receive data
RPOS/RNEG or RDAT is clocked out on the rising edge of RCLK.
RCLK output can be inverted. If a given receiver is in power-down
mode, the RCLK is high impedance.

Master Clock.
This is an independent free-running clock that can
be a multiple of 2.048MHz ±50ppm for E1 mode or 1.544MHz
±50ppm for T1 mode. The clock selection is available by
MC
bits
MPS0, MPS1, FREQS, and PLLE. A multiple of 2.048MHz can be
internally adapted to 1.544MHz and a multiple of 1.544MHz can
be internally adapted to 2.048MHz. In hardware mode, internal
adaptation is not available so the user must provide 2.048MHz
±50ppm for E1 mode or 1.544MHz ±50ppm for T1 mode.

RLOS1:
This output goes high when there is no transition on the
received signal over a specified interval. The output goes low
when there is sufficient ones density in the received signal. The
RLOS criteria for assertion and desertion criteria are described in
the
Functional Description
section. The RLOS outputs can be
configured to comply with T1.231, ITU G.775, or ETSI 300 233. In
hardware mode, ETSI 300 233 “RLOS Criteria” is not available.
TECLK:
When enabled by register
MC
, this output becomes a T1-
or E1-programmable clock output. For T1 or E1 frequency
selection, see register
CCR

hardware mode.
