DTE Interface Configuration Options
Table C-1. DTE Interface Configuration Options
C-2
DTE Framing: ESF (Factory 1)
Next D4 ESF Prev
DTE Line Framing Format. Designates the framing format for the DTE interface.
–
D4 Configures for the D4 framing format.
–
ESF Configures for the Extended Superframe framing format.
DTE Coding: B8ZS (Factory 1)
Next AMI B8ZS Prev
DTE Line Coding Format. Designates the line coding format to be used on the DTE
interface.
–
AMI Uses the Alternate Mark Inversion coding format.
–
B8ZS Uses the Bipolar 8 Zero Suppression coding format.
Equal: 0—133
Next 0—133 133—266
DTE Line Equalization. Specifies the DTE line equalization compensation parameters that
permit a standard DTE signal to be delivered over a distance of up to 655 feet.
Extrn DLB: Disab
Next Enab Disab Prev
DTE Loopback on External Contact. Allows the control of a DTE Loopback (DLB) by an
external contact on the DTE interface.
–
Enab Allows the CSU to begin a DLB when the external contact is closed. The CSU
remains in DLB as long as the contact remains closed.
–
Disab Prevents the state of the external contact from affecting the operation of DLB.
Send AIS: Enab
Next Enab Disab Prev
Send Alarm Indication Signal (AIS) on Network Failure. Specifies the action to take on the
signal transmitted to the DTE when a valid signal cannot be recovered from the network
interface (due to an LOS or OOF condition).
–
Enab Sends an AIS to the DTE when an LOS or OOF condition occurs on the network.
–
Disab Passes the failed network signal on to the DTE unchanged.
Yellow: Enab
Next Enab Disab Prev
Transcode Yellow Alarm Signal to DTE. Specifies whether a yellow alarm signal received
on the network interface is transcoded and transmitted to the DTE. This configuration
option does not appear if both the network and DTE interfaces are set to the same format
(either ESF or D4). For D4 format, a yellow alarm signal is sent by setting Bit 2 of each
timeslot to zero. For ESF format, a yellow alarm is sent by continuously sending 8 ones
followed by 8 zeros on the Facility Data Link (FDL).
–
Enab Transcodes the signal transmitted to the DTE.
–
Disab Disables transcoding.
