Parameter Description/Action
DTE Interface This allows you to select V.35, RS449, X.21 or HSSI as the DTE Interface.
To change the present DTE Interface, use the UP and DOWN ARROW
keys to highlight DTE Interface. Use the Space Bar to toggle between
V.35, RS-449, X.21, and HSSI until the desired choice appears. Highlight
Confirm, and press the Enter key to confirm the change. (Default - V.35)
DTE Toggle Interval This parameter determines the length of the interval during which the DTE
lead indicating signal presence is deasserted when a change in the DTE
data rate occurs.
The DTE data rate changes if a network port goes or is taken out of
service, or if a network loopback is set. The DTE lead toggled is RLSD in
V.35, RS449, and X.21 modes, and CA in HSSI mode. This toggle
interval is needed by some DTE devices to allow resynchronization to the
new data rate. THe interval may be set to NONE, 0.5, 1.0, 1.5, or 2.0
seconds. (Default - NONE)
Clock This item allows you to enable either the SCT or SCTE leads, and to set the
transmit (Tx), and receive (Rx) to Normal or Inverted mode.
Note: In x.21 mode SCT corresponds to the S clock signal and SCTE to
the x clock signal.
To set the DTE Clock parameters, use the UP and DOWN ARROW keys to
highlight the configurable Clock items, and use the Space Bar to toggle
between the selections until the desired choice appears. The options are
SCT or SCTE, Tx Normal or Inverted, and Rx Normal or Inverted. When
the desired selection is in the display, highlight Confirm, and press the
Enter
key to confirm the change (Default - SCTE, Tx Normal, Rx Normal)
RLSD (Receive Line Signal
Detector) This allows you to Assert, DeAssert, or set to Automatic the RLSD leads.
To change or set the RLSD lead status, use the UP and DOWN ARROW
keys to highlight RLSD, and use the Space Bar to toggle between Assert,
DeAssert, or Automatic until the desired choice appears. Highlight
Confirm, and press the Enter key to confirm the change. (In Automatic
mode, the 3800E places the signal high when you have a clear signal
from the network, indicating the E1 is up and running.)
In X.21 mode, RLSD refers to the X.21 signal called Indication. (Default -
Automatic)
