DTE Interface Configuration Options

DTE Port: Enab

Next Enab Disab Prev

DTE Drop/Insert Port. Enables the use of the DTE Drop/Insert port.

Enab ± Allows the use of the DTE Drop/Insert interface.

Disab ± Prohibits the use of the DTE Drop/Insert interface.

NOTE: When this configuration option is disabled, you cannot display or configure any other DTE Interface configuration options and TS16 is set to data. If a clock source configuration option is set to DTE, it is changed to NET.

DTE Frame: noCRC

Next CRC4 noCRC Prev

DTE Line Framing Format. Designates the framing format for the DTE Drop/Insert interface.

CRC4 ± Configures for the CRC4 framing format.

noCRC ± Configures for the non-CRC4 framing format.

DTE Coding: HDB3

Next AMI HDB3 Prev

DTE Line Coding. Designates the line coding format to be used on the DTE Drop/Insert interface.

AMI ± Uses the Alternate Mark Inversion coding format.

HDB3 ± Uses the High Density Bipolar 3 coding format.

Extrn DLB: Disab

Next Enab Disab Prev

DTE Loopback on External Contact. Allows the initiation and termination of a DTE Loopback (DLB) by an external contact. For more information, see the DTE Drop/Insert Interface section in Appendix D, Pin Assignments.

Enab ± Allows the E1 DSU/CSU to begin a DLB when the external contact is closed (if the current E1 DSU/CSU state allows a DLB to be performed). If the E1 DSU/CSU is already performing a DLB, closing the contact will have no effect. Opening the contact takes the E1 DSU/CSU out of DLB. The E1 DSU/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 Ones: Enab

Next Enab Disab Prev

Send All Ones on DTE Drop/Insert Failure. Specifies the action to take on the signal transmitted to the network when a valid signal cannot be recovered from the DTE Drop/Insert interface (due to an LOS, OOF, or AIS condition).

Enab ± Sends all ones on the DS0 channels allocated to the network interface when an LOS, AIS, or OOF condition occurs on the DTE Drop/Insert interface.

Disab ± Passes the data unchanged to the network interface channels.
