7) Adjust R2 to about half range on the GETC. The procedures to test the Rockwell Modem follows: l) Plug the Rockwell Modem into the test fixture.

2) Apply power (13.8 volts) to the GETC shelf and the SIMON welcome message is displayed on the terminal. The GETC is DTP switch configured for SIMON operation prior to power up. See 19A701179 for dip switch set-up.

3) Type "TIM 19" on the terminal to set the time delay from RTS to beginning of data to 250 milliseconds.

4) Execute the SIMON command "MDS 1" to select the phone modem for subsequent BER command.

5) Execute the SIMON command "BER DE-00=10". This command transmits data and simultaneously checks to see that data is being received. The terminal should respond with the following: Error Count = 0000 Receive Checksum = 00188123

If the terminal does not respond with the above data, the Rockwell Modem has failed the test and needs to be returned to the vendor.

The test continually runs, outputting data to the terminal in 10 second intervals.

6) After four consecutive test periods (10 seconds per test pe riod) with data o utputted to the terminal, the test can be terminated by pressing a CTRL Z or the ESC key on the terminal.

The 2400 bps data stream is encoded into dibits forming a 4 point structure, and the 4800 bps data stream is encoded into quadbits forming a l6-point structure. The first 32 bauds of data are transmitted at 2400 bps and the remaining message is transmitted at 4800 bps.

At 300 baud, the 300 bps data stream is encoded per CCITT V.21 Channel 2 into a mark frequency of I650 Hz and a space frequency of 1850 Hz

Equalizers

The R96FT provides equalization functions that improve performance when operating over low quality lines.

Cable Equalizers

- Selectable compromise cable equalizers in the receiver and transmitter are provided to optimize performance over different lengths of non-loaded cable of 0.4 mm diameter.

Link Equalizers

- Selectable compromise link cable equalizers in the receiver optimize performance over channels exhibiting severe amplitude and delay distortion. Two standards are provided: U.S. survey long and Japanese 3-link.

Automatic Adaptive Equalizer

- An automatic adaptive T

equalizer is provided in the receiver circuit

Transmitted Data Spectrum

If the cable equalizer is no enabled the transmitter spectrum is shaped by the following raised cosine filter functions:

Data Encoding

At 2400 baud. the data stream is encoded per CCITT V.29. At 9600 bps, the data stream is divided in groups of fourbits (quadbits) forming a 16-point structure. At 7200 bps, the data stream is divided into three bits (tribits) forming an 8-point structure. At 4800 bps. the data stream is divided into two bits (dibits) forming a 4-point structure.

REVISIONS

The R96FT incorporates a self-synchronizing scrambler/ descrambler. This facility is in accordance with either V.27 bis/ter or V.29 depending on the selected configuration.

The scrambler/descrambler facilities for Gearshift can be selected to be in accordance with either V.27 bis/ter or V.29. The scrambler/descrambler selection is made by writing the appropriate configuration codes into the transmitter and receiver.

Received Signal Frequency Tolerance

The receiver circuit of the R96FT can adapt to received frequency error of up to ±10 Hz with less than 0.2 dB degradation in BER performance.

During fast train polling, frequency offset must be less than ±2 Hz for successful training.

Receive Level

The receiver circuit of the modem satisfies all specific performance requirements for received line signal levels from 0 dBm to -43 dBm. The received line signal level is measured at the receiver analog input (RXA).

Receive Timing

The R96FT provides a data derived Receive Data Clock (RDCLK) output in the form of a squarewave. The low-tohigh transitions of this output coincide with the centers of received data bits. For the Gearshift configuration, the first 32 bauds of data are at 2400 bps followed by 4800 bps data for the remaining message. The timing recovery circuit is capable of racking a ±0.0l% frequency error in the transmit

timing source. RDCLK duty cycle is 50.% ±1%.

The R96FT provides a Transmit Data Clock (TDCLK) output with the following characteristics:

1. Frequency. Selected data rate of 9600,7200.4800,2400

or 300 Hz (±0.01%). For the Gearshift configuration, TDCLK is a 2400 Hz clock for the first 32 bauds of data and a 4800 Hz clock for the remaining message.

2. Duty Cycle. 50% ±1%

Input data presented on TXD is sampled by the R96FT at the low-to-high transition of TDCLK. Data on TXD must be stable for at least one microsecond prior to the rising edge of TDCLK and remain stable for at least one microsecond after the rising edge of TDCLK.

External Transmit Clock

The transmitter Data clock (TDCLK) can be phase locked to a signal on input XTCLK. This input signal must equal the desired data rate ±0.01 with a duty cycle of 50% ±20%.

Train On Data

When train on data is enabled (by setting a bit in the interface memory), the modem monitors the EOM signal. If EOM indicates a loss of equalization (i.e., BER approximately 10

-3

for 0.5 seconds) the modem attempts to retrain on the data stream. The time for retrain is typically 3 to 15 seconds.

Turn-On Sequence

A total of 20 selectable turn-on sequences can be generated as defined in the following table:

Transmit Level

The transmitter output level is accurate to ±1.0 dB and is programmable from -l.0 dBm to -l5.0 dBm in 2dB steps.

Turn-Off Sequence

For V.27 bis/ter, V.27FT and 2400/4800 bps Gearshift configurations, the turn-off sequence consists of approximately 10 ms of remaining data and scrambled ones followed by a 20 ms period of no transmitted energy (V.27 bis/ter only). For V.29 and V.29FT, the turn-off sequence consists of approximately 8 ms of remaining data and scrambled ones.

Clamping

Response

For Fast Train and Gearshift configurations, the receiver enters the training state upon detecting a significant increase in the received signal power. If the received line signal power is greater than the selected threshold level at the end of the training state, the receiver enters the Data state and RLSD is activated. If the received line signal power is less than the selected threshold level at the end of the training state, the receiver returns to the idle state and RLSD is not activated.

Also, in Fast Train and Gearshift configurations, the receiver initiates the turn-off delay upon detecting a significant decrease in the received signal power. If the received signal power is less than the selected threshold at the end of the turn-off delay, the receiver enters the idle state and RLSD is deactivated. If the received signal power were greater than the selected threshold at the end of the turn-off delay, the receiver returns to the data state and RLSD is left active.

For CCITT configurations, the receiver enters the training detection state when the received line sign power crosses the selected threshold level. RLSD is activated at the end of the training sequence. For V.21 Channel, a separate received line signal detector (FRLSD) is provided. FRLSD is activate when energy above -43 dB is present at the receiver’s audio input (RXA). The FRLSD off-to-on response time is 15 ±1.5ms and the on-to-off response time

is 25 ±1.5ms.

Received Data (RXD) is clamped to a constant mark (one) when the Received Line Signal Detector (RLSD) is off.

Response Times Of Clear To Send (CTS)

The time between the off-to-on transition of Request To Send (RTS) and the off-to-on transition of Clear to Send (CTS) is dictated by the length of the training sequence and the echo protector tone. if used. These times are given in the Turn-on Sequences table. If training is not enabled. RTS/CTS delay is less than 2 baud times.

The time between the on-to-off transition of RTS and the on-to-off transition of CTS in the data state is a maximum of 2 baud times for all configurations.

For CCITT configurations. a minimum hysteresis action of 2dB exists between the actual off-to-on and on-to-off transition levels. The threshold levels and hysteresis action are measured with unmodulated 2100 Hz tone applied to the receiver’s audio signal input (RXA)

MODES OF OPERATION

The R96FT has the capability of transferring channel Data (up to eight bits at a time) via the microprocessor bus.

Mode Selection

For the transmitter, a control bit determines whether the source of transmitted data is the V.24 interface (serial mode) or the parallel transmitter data register (parallel mode).The transmitter automatically defaults to three serial mode at power-on.

The receiver simultaneously outputs received data via the V.24 interface and he parallel receiver data register.

In either parallel or serial mode, the R96FT is configured by the host processor via the microprocessor bus.

INTERFACE CRITERIA

The modem interface comprises both hardware and software circuits. Hardware circuits are assigned to specific pins in a 64-pin DlN connector. Software circuits are assigned to specific bits in a 48-byte interface memory.

The R96FT capable of being operated in either a serial or a parallel mode of operation.

Serial Mode

The serial mode uses standard V.24 (RS-232-C compatible) signals to transfer channel data. An optional USRT device (shown in the Functional Interconnect Diagram) illustrates this capability.

The four hardware diagnostic circuits, identified in the following table, allow the user to generate and display an eye pattern. Circuits EYEX and EYEY serially present eye pattern data for the horizontal and vertical display inputs respectively. The 8 bit data words are shifted out most Significant bit first, clocked by the rising edge of the EYECLK output. The EYESYNC output is provided for word synchronization. The falling edge of EYESYNC may be used to transfer the 8-bit word from the shift register to a holding register. Digital to analog conversion can then be performed for driving the X and Y inputs of an oscilloscope.

the transmitter for the purpose of interacting with user provided equipment. Because this is a sampled data input, any signal above 4800 Hz will cause aliasing errors. The input impedance is 1K ohms, and the gain to transmitter output is TLVL setting +0.6 dB

-l.4 dB. If unused, this input must be grounded near the modem connector. If used, it must be driven from a low impedance source.

Software Circuits

The R96FT comprises three signal processor chips. Each of these chips contains 16 registers to which an external (host) microprocessor has access. Although these registers are within the modem, they may be addressed as part of the processor's memory space. The host may read data out of or write data into these registers. The registers are referred to as interface memory. Registers in chip 1 update at half the modem sample rate (4800 bps). Registers in chip 0 and 2 update at the selected baud rate.

When information in these registers is being discussed, the format Y:Z:Q is used. The chip is specified by Y(0-2), the register by Z(0-F), and the bit by Q(0-7, 0 = LSB).

Status Control Bits

The operation of the F96FT is affected by a number of software control inputs These inputs are written into registers within the interface memory via the host microprocessor bus. Modem operation is monitored by various software flags that are read from interface memory via the host microprocessor bus. All status and control bits are defined in the Interface Memory table. Bits, designated by a dash (—) are reserved for modem use only and must not be changed by the host.

RAM Data Access

The R96FT provides the user with access to much of the data stored in the modem's memories. This data is useful for performing certain diagnostic functions

Two RAM access registers in chip 2 allow user access to RAM locations via the X word registers (2:2 and 2:2) and the Y word register (2:1 and 2:0). The access code stored in RAM ACCESS X (2:5) selects the source of data for RAM DATA XM and RAM DATA XL (2:3 and 2:2). Similarly, the access code stored in RAM ACCESS Y (2:4) selects the source of data for RAM DATA Y and RAM DATA YL(2:1 and 2:0).

Reading of diagnostic RAM data is performed by storing the necessary access codes in 2:5 and 2:4, reading 2:0 to reset the associated data available bit (2:E:0), then waiting for the data available bit to return to a one. Data is now valid and may be read from 2:3 through 2:0.

An additional diagnostic is supplied by the sample rate processor (chip 1). Registers 1:2 and 1:3 supply a 16 bit AGC Gain Word. These two diagnostic data registers are updated at the sample rate during the data state and may be read by the host processor asynchronously.

2. The FSK receiver is active at all times. Two ancillary hardware circuits, FRLSD and FRXD, are supplied for FSK message reception. FRLSD is described under the Received Line Signal Detector section. FRXD provides inverted FSK received data. Timing extraction must be performed on the FRXD signal externally as no FSK receiver data clock is provided by the R96FT.

0:7:2

When control bit TPDM is a one, the transmitter accepts data for transmission form the transmitter data register (0:0) rather than the serial hardware data input.

0:6:0-7 The host processor configures the transmitter by writing a control byte into the transmitter

configuration register in its interface memory space. (See TSB) Transmitter Configuration Control Codes Control codes for the modem transmitter configurations are:

must write a one in this control bit. TSB goes to a zero when the change becomes effective. Worst case setup time is 2 baud + turnoff sequence + training (if applicable).

0:7:6 When control bit TTDIS is a one, the transmitter does not generate a training sequence at the start of

transmission. With training disabled, RTS/CTS delay is less than two baud times.

0:7:1 When control bit XCEN is a one, the transmitter timing is established by the external clock supplied

at the hardware input XTCLK, pin 22A.

PERFORMANCE

Whether functioning in V.27, V.29 or the proprietary fast train configurations, the R96FT provides the user with high

performance. Approximately 10 ms after the low to high transition of POR, the modem is ready to be configured, and RTS may

be activated. If the 5 Vdc power supply drops below 3.5 Vdc for more than 30 msec, the POR cycle is generated.

At POR time the modem defaults to the following configuration: fast train, V.29, 9600 bps, no echo protector tone, 1700 Hz carrier frequency, scrambled ones segment disabled, serial data mode, internal clock, cable equalizers disabled, transmitter digital delay equalizer disabled, transmitter output level set to -1 dBm ± 1 dB, interrupts disabled, receiver threshold set to -43 dBm, and train-ondata enabled.

POR can be connected to a user supplied power-on-reset signal in a wire-or configuration. A low active pulse of 3

In the 9600 bps fast train configuration the modem

approaches a 98% success rate over unconditioned 3002

lines for a signal-to-noise ratio of 26 dB, with a received

signal level of -20 dBm.

Bit Error Rates

The Bit Error Rate (BER) performance of the modem is

specified for a test configuration conforming to that

specified in CCITT Recommendation V.56. Bit error rates

are measured at a received line signal level of -20 dBm as

illustrated. µsec or more applied to the POR pin causes the modem to

reset. The modem is ready to be configured 10 msec after POR is removed.

Both modems are configured as follows:

1) Set modem DIP switches (located on back of modem) as shown:

DUAL 12345678910 U DUDUUUDDDD

2) Attach a terminal or PC to the modem using a straight-through (modem) cable. This may be a full ribbon cable or a DEC BC22E. Set the terminal to 9600 baud, 8-bit, no parity ONLY. Failure to do so will cause unreliable behavior from the modem once it is installed.

3) Apply power to the modem. You should be able to type the two letters "AT" followed by a carriage return and receive an "OK" response. If the modem does not respond, check the cable and steps 1-2 above.
