5.0 OPERATION

Once you have configured each Model 1080A Series unit properly and connected the twisted pair and RS-232 cables (see Section 4.0), you are ready to operate the units. This section describes reading the LED status monitors, powering-up and using the built-in V.52 and V.54 test modes.

5.1 LED STATUS MONITORS

The Model 1080A Series features six front panel status LEDs that indicate the condition of the modem and communication link. Figure 5 shows the front panel location of each LED. Following Figure 5 is a description of each LED's function.

5.1.1 The “TD” and “RD” Indicators

The “TD” and “RD” indicators blink red and green with data activity. Red indicates a low RS-232 logic level, green indicates a high RS-232 logic level. Note: RS-232 devices idle in a low state, so the LED will glow red if the connections are correct and the RS-232 device is in an idle state.

5.1.2 The “RTS” and “CD” Indicators

The “RTS” and “CD” indicators are bi-color and will glow red for a “low” signal or green for a “high” signal. RTS lights for an incoming signal on RS-232 pin 4. CD lights for an incoming signal on the line side, and the resulting output signal on RS-232 pin 8.

5.1.3 The “Test” Indicator

The green “Test” LED indicates that V.52 or V.54 tests are running.

5.1.4 The “Error” Indicators

The “Error” indicator LED has three functions:

A.When the 1080A Series unit is in test mode (green “Test” LED is lit), the error LED glows red when bit errors occur.

B.When not in test mode (green “Test” LED is off), the error LED is used to indicate an RTS streaming condition. (See Section 5.2) for information on the anti-streaming circuitry.

C.The “Error” LED is also used to detect line quality, such:

1.The improper use of flat (non-twisted pair) cable to connect the modems.

2.One or more broken wire in the 4 wire twisted pair cable.

3.The use of low quality twisted pair cable to connect the modems.

4.Broken or corroded connector.

NOTE: In detecting line quality the “Error” LED indicator is designed for 4 wire twisted pair cable only, and may not function properly with two wire cable.

5.1.4.1 Setting Up The “Error” LED To Test Cable Quality

If there is any question as to the quality of your line we recommend the following test:

1.Disconnect both local and remote modems from their RS-232 interface. Make sure “TD”, “RD” and “RTS” LEDs are lit red.

2.Set input impedance of both modems to 200Ω . (S3-1 “On”, S3-2 “Off”).NOTE: When testing Model 1080A-64, use 22AWG, 24AWG, or 26AWG cable only,

3.For Model 1080A, set data rate on both modems for 9.6kbps For Model 1080A-64, set data rate on both modems at 16 kbps.

4.On local modem set “Carrier Constantly On”. (S1-8 “Off”)

5.Set remote modem to RTS control (S1-8, “On”).

6.Place both front panel toggle switches to neutral position. (Test Led will not light)

7.Connect both modems to the 4 wire twisted pair cable.
