TDM Interface:
Receive Side System Data (links 1-8) The processed data stream is an output to MPC8560.
RSD:
RSFS:
Receive Side System Frame pulse (links 1-8) In T1/J1 receive clock master mode, RSFSn
outputs the pulse; T1/J1 receive clock slave mode, RSFSn inputs the pulse. In E1 receive
clock master mode, RSFSn outputs the pulse; in E1 receive clock slave mode, RSFS inputs
the pulse.
TSCK:
Transmit Side System Clock (links 1-8) In transmit clock master mode, the TSCKn outputs
a 1.544 MHz (T1/J1)/2.048 MHz (E1) clock. In transmit clock slave mode, the TSCKn inputs a
1.544 MHz (T1/J1 only), 2.048 or 4.096 MHz clock.
TSD:
Transmit Side system Data (links 1-8) The data stream from MPC8560 is an input.
Transmit Side System Frame pulse (links 1-8) In T1/J1 transmit clock master mode, TSFSn
TSFS:
outputs the pulse; in T1/J1 transmit clock slave mode, RSFSn inputs the pulse. In E1 transmit
clock master mode, TSFSn outputs the pulse; in E1 transmit clock slave mode, TSFS inputs
the pulse.

FRAMER WAVEFORM SHAPE

The framer provides a mechanism to tune the transmitted waveform. This mechanism is
described in the IDT82P2288 data sheet (see the technical reference in
"User-Programmable Arbitrary Waveform." It consists of loading values to describe the
wave form into the framer RAM and a scale value into a chip register. This procedure is
repeated for each of the ports being used. The data sheet defines the values to load into
RAM as a series of tables numbered from 62 to 73. Which table and scale value to use is dic-
tated by the mode (T1 or E1) and the Rear Transition Module (RTM) ports.
fies the table and scale value to use based on these two parameters.

Scale values for other Emerson RTMs are available upon request, contact Technical Support.

FRAMER INTERRUPT MECHANISM

Special events in the framer are indicated by means of a single interrupt output (INT* pin
T11) with programmable characteristics (open drain). This requests the processor to read
status information from the framer, or to transfer data from/to the framer. Since only one
INT* request output is provided, the processor must determine the cause of an interrupt by
reading the framer's Interrupt Status registers (ISR0 and ISR1). That means the interrupt at
pin INT* and the interrupt status bits are reset by reading the interrupt status registers.
