Page 13: Jumper S1 − Carrier Detect Control
Installation Note: The jumper positions in the following sections reflect the position of the jumpers on the modem board when you face the board as indicated in Figure 2-4 on page 12. Jumper S1 − Carrier Detect Control Settings: Jumper S1 configures the dynamic range of the modem receiver. The selections are either –33 dBm or –43 dBm. -
Page 14: Jumper S3 − 2-Wire/4-Wire Mode
Jumper S3 − 2-wire/4-wire Mode Settings: Jumper S3 configures the modem for 2-wire or 4-wire operation. c When configured for 4-wire full-duplex operation, jumper S5 can be strapped to maintain constant carrier from the master modem to all slave modems at all times after the initial training. This enables the master modem to transmit data to the slave modems, with no RTS-to-CTS delay. -
Page 15: Jumper S5 − Transmit Carrier
Installation Jumper S5 − Transmit Carrier Jumper S5 places the transmitter under terminal control (default) or turns on the transmitter continuously in a 2-wire half duplex system. Jumper S6 − Local Copy Jumper S6 must be left is the default position of Disabled when operating on a 4-wire network. -
Page 16: Jumper S9 − Rts-Cts Delay
Jumper S9 − RTS-CTS Delay Jumper S9 configures the modem’s RTS-CTS delay. Four choices for selecting an RTS-CTS delay are available. Jumper S10 − Carrier Detect Delay Jumper S10 configures the modem’s Carrier Detect turn on Delay timing. The delay chosen must be consistent with the Clear To Send delay selection of the transmitting modem and must be less than the CTS delay. -
Page 17: Jumper S12 − Soft Carrier Turn Off
Installation Jumper S12 − Soft Carrier Turn Off Jumper S12 configures the modem to either turn off the transmitter immediately upon release of Request To Send, or send a Soft Carrier Turn Off signal of 900 Hz for 8 or 26 ms at the end of each transmission. -
Page 18: Jumpers S14 And S15 − Self Test Or Test Pattern
Jumpers S14 and S15 − Self Test or Test Pattern Jumpers S14 and S15 configures the modem for Self Test or Test Pattern. When the modem is in local Self Test or Test Pattern mode, it generates a dot test pattern. The supported baud rates are 1 bps, 18 bps, 37 bps, 75 bps, or 150 bps. -
Page 19: Powering-On The Modem
Installation Powering-on the Modem To supply power to the modem, place the POWER ON switch on the modem back panel to the ON position. The PWR LED on the front panel goes ON. Powering-off the Modem To turn off power to the modem, place the POWER ON switch on the modem back panel to the OFF position. -
Page 20: Chapter 3 Leds And Controls
his chapter describes the LEDs and controls on the modem. Front Panel LEDs Table 3-1 describes the LEDs on the modem front panel. ON = power is being supplied to the modem. ON = the rotary switch is turned to Analog or Digital Loopback, or the switch is in the Test Pattern transmit mode or Self Test mode and no error is detected. -
Page 21: Front Panel Test Switch
Troubleshooting Front Panel Test Switch The modem front panel has a five-position rotary switch that lets you select the modem’s operating mode. The five switch positions are: c DATA use this position for normal data transmissions. c AL (Analog Loopback) this position prepares the modem for testing by the local terminal device. -

Page 24: Chapter 4 Troubleshooting
his chapter describes troubleshooting procedures you can use in the unlikely event you encounter a problem with your modem. Local Modem Test The local modem test verifies the local modem’s transmitter, receiver, and connection to the locally attached DTE. This test can be run either by generating a data pattern from the locally attached DTE or by having the modem generate a test pattern. -
Page 25: Line And Modem Test
Specifications Line and Modem Test The line and modem test verifies the local modem, the remote modem, and the communications line between them. With this test, the local modem loops back received data to the transmitter and transmits the data to the remote modem. These characters can originate either from a locally attached DTE or by having the modem generate a test pattern. -
