† After RESET is deasserted, the channel is in the default framing mode, as a function of the DS1/CEPT pin.
‡ Asserting this pin low will initially force RDY to a low state.

Receive CHI Data B. Serial input system data at 2.048 Mbits/s,
4.096 Mbits/s, or 8.192 Mbits/s.
Loss of Receive Clock. This pin is asserted high (logic 1) when RLCK
in the receive framer does not toggle for a 250 s interval. Once
asserted, this signal is deasserted on the first edge of RLCK (See Table
66. Global Control Register (GREG8) (008)).
Receive Framer Line Interface Clock. This is the 1.544 MHz DS1 or
2.048 MHz input clock signal used by the receive framer to latch RPD
and RND data.
Receive Positive-Rail Data. NRZ serial data latched by the rising edge
of RLCK. Data rates: DS1 - 1.544 Mbits/s; CEPT - 2.048 Mbits/s. Optional
single-rail NRZ receive data latched by the rising edge of RLCK.
Receive Negative-Rail Data. Nonreturn-to-zero (NRZ) serial data
latched by the rising edge of RLCK. Data rates: DS1 - 1.544 Mbits/s;
CEPT - 2.048 Mbits/s. In the single-rail mode, when RND = 1 the receive
bipolar violation counter increments once for each rising edge of RLCK.
