#### Clocking Mode

  This field defines the DTE clocking mode. Most applications do not require inverting the DTE clock, but occasionally, shifting the DTE clock 180 degrees will solve out-of-phase timing problems on the DTE link.
  Range: Normal or Inverted

#### Timing

  Timing may be looped internally from the unit (Loop 2), or externally from the DTE device (Loop 1). If a problem with DTE timing occurs or if you are uncertain which to use, configure the unit for Loop-2 timing.
  Range: Loop-1 or Loop-2

#### Interface

  This field identifies the type of electrical interface accepted by the DTE port. Currently, the Probe only supports the V-35 electrical interface.
  Range: V.35

#### Data

  This field defines the DTE data inversion option. Most applications do not require inverting DTE data, however, occasionally (particularly HDLC-based protocols) inverting DTE data, like when zeros become ones and ones become zeros, will enable you to meet density requirements even across clear channel DS0s in AMI mode.
  Range: Normal or Inverted

#### DTR

  This field defines whether the DTR signal will be Monitored or Ignored.
  Note: Envisage adds polling for appropriate variables at appropriate times. If Ignored, the calculated status (color of the port) wil be as if it were active. If the signal is to be Monitored, the actual value of the signal status will be reflected in the calculated status. Since default value is Monitored, user will see a red port if DTR is not present. If this situation is not acceptable, user can change the configuration to ignore the appropriate signal and Envisage will not use the signal status in calculating its consolidated status for the port
  Range: Monitored or Ignored

#### RTS

  This field defines whether the RTS signal will be Monitored or Ignored.
  Note: Envisage adds polling for appropriate variables at appropriate times. If Ignored, the calculated status (color of the port) wil be as if it were active. If the signal is to be Monitored, the actual value of the signal status will be reflected in the calculated status. Since default value is Monitored, user will see a red port if RTS is not present. If this situation is not acceptable, user can change the configuration to ignore the appropriate signal and Envisage will not use the signal status in calculating its consolidated status for the port
  Range: Monitored or Ignored

#### Rate

  This field identifies the DTE serial data rate in bits-per-second. This value must be a multiple of 8000. Valid data rates depend on the Density setting; Bit-7 Stuffing allows n X 56-Kbps, Clear Channel allows n X 64-Kbps, where n equals an integer between 1-24 (DSOs) inclusive.
  Range: 8000 -- 1536000

#### Density

  This field identifies the type of DS0 density (packing of serial data into DS0s).
  Range: Bit-7 Stuffing (each 8th bit is forced high. DTE data rates of n X 56-Kbps are supported, where n equals an integer between 1-24 (DSOs) inclusive. This form of density normally provides sufficient ones-density), or Clear Channel (DTE data rates of n X 64-Kbps are supported. This form of density may require an additional means of density enforcement such as B8ZS.

#### Starting DS0

  Defines the DS0 start value.
  Range: 1 ~ 24

#### Auto Connect

  Enables or disables the Auto Connect feature.
  Important Note: Do not change this feature to "No" unless directed to by Sync Research
  Range: Yes or No
  Default: Yes
