DESCRIPTION
21
RYEL
0
Receive Yellow Alarm.
Transitions high when yellow alarm detected, goes low
when alarm clears.
22
RLINK
0
Receive Link Data.
Updated with extracted FDL data one RCLK before start of
odd frames (193E) and held until next update. Updated with extracted S-bit data one
RCLK before start of even frames (193S) and held until next update.
23
RLCLK
0
Receive Link Clock.
4 kHz demand clock for RLINK.
24
RCLK
I
Receive Clock.
1.544 MHz primary clock.
25
RCHCLK
O
Receive Channel Clock.
192 kHz clock identifies time slot (channel) boundaries.
26
RSER
O
Receive Serial Data.
Received NRZ serial data, updated on rising edges of RCLK.
27
RFSYNC
O
Receive Frame Sync.
Extracted 8 kHz clock, one RCLK wide, indicates F-Bit
position in each frame.
28
RMSYNC
O
Receive Multiframe Sync.
Extracted multiframe sync; edge indicates start of
multiframe, 50% duty cycle.
29
RABCD
O
Receive ABCD Signaling.
Extracted signaling data output, valid for each channel
time in signaling frames. In non-signaling frames, RABCD outputs the LSB of each
channel word.
30
RSIGFR
O
Receive Signaling Frame.
High during signaling frames, low during resync and
non-signaling frames.
31
RSIGSEL
O
Receive Signaling Select.
In 193E framing a .667 kHz clock which identifies
signaling frames A and C. A 1.33 kHz clock in 193S.
33
RST
I
Reset.
A high-low transition clears all internal registers and resets receive side
counters. A high-low-high transition will initiate a receive resync.
34
35
RPOS
RNEG
I
Receive Bipolar Data Inputs.
Samples on falling edge of RCLK. Tie together to
receive NRZ data and disable bipolar violation monitoring circuitry.
36
RCL
O
Receive Carrier Loss.
High if 32 consecutive 0's appear at RPOS and RNEG; goes
low after next 1.
37
RBV
O
Receive Bipolar Violation.
High during accused bit time at RSER if bipolar
violation detected, low otherwise.
38
RFER
O
Receive Frame Error.
High during F-Bit time when FT or FS errors occur (193S)
or when FPS or CRC errors occur (193E). Low during resync.
39
RLOS
O
Receive Loss of Sync.
Indicates sync status; high when internal resync is in
progress, low otherwise.
