3.1.2 Receive Side
Signal Name:
Signal Description:
Signal Type:
T1 Mode: Updated with either FDL data (ESF) or Fs bits (D4) or Z bits (ZBTSI) one RCLK before the start of a
frame.
E1 Mode: Updated with the full E1 data stream on the rising edge of RCLK.
Signal Name:
Signal Description:
Signal Type:
T1 Mode: A 4kHz or 2kHz (ZBTSI) clock for the RLINK output.
E1 Mode: A 4kHz to 20kHz clock.
Signal Name:
Signal Description:
Signal Type:
1.544MHz (T1) or 2.048MHz (E1) clock that is used to clock data through the receive-side framer.
Signal Name:
Signal Description:
Signal Type:
A 192kHz (T1) or 256kHz (E1) clock that pulses high during the LSB of each channel. Synchronous with RCLK
when the receive-side elastic store is disabled. Synchronous with RSYSCLK when the receive-side elastic store is
enabled. Useful for parallel-to-serial conversion of channel data.
Signal Name:
Signal Description:
Signal Type:
A user-programmable output that can be forced high or low during any of the 24 T1 or 32 E1 channels.
Synchronous with RCLK when the receive-side elastic store is disabled. Synchronous with RSYSCLK when the
receive-side elastic store is enabled. Useful for blocking clocks to a serial UART or LAPD controller in
applications where not all channels are used such as fractional service, 384kbps service, 768kbps, or ISDN–PRI.
Also useful for locating individual channels in drop-and-insert applications, for external per-channel loopback, and
for per-channel conditioning. See Section 17 for details.
Signal Name:
Signal Description:
Signal Type:
Received NRZ serial data. Updated on rising edges of RCLK when the receive-side elastic store is disabled.
Updated on the rising edges of RSYSCLK when the receive-side elastic store is enabled.
Signal Name:
Signal Description:
Signal Type:
An extracted pulse, one RCLK wide, is output at this pin that identifies either frame (IOCR1.5 = 0) or multiframe
(IOCR1.5 = 1) boundaries. If set to output frame boundaries, then through IOCR1.6, RSYNC can also be set to
output double-wide pulses on signaling frames in T1 mode. If the receive-side elastic store is enabled, then this pin
can be enabled to be an input through IOCR1.4, at which a frame or multiframe boundary pulse is applied.
Signal Name:
Signal Description:
Signal Type:
An extracted 8kHz pulse, one RCLK wide, is output at this pin that identifies frame boundaries.
