Network-initiated DSU Loopback (64K CC)

Possible Settings: Enable, Disable

Default Setting: Enable

Indicates whether the access unit responds to a DSU latching loopback sequence sent by the network as specified by TR62310.

HNetwork-initiated DSU Loopback (64K CC) option appears when Operating Mode is set to DDS in Table A-1.

Enable ± Responds to network-initiated commands to start and stop a latching DSU loopback.

Disable ± DSU will not respond to a DSU loopback initiated by the network.

Data Scrambling (64K CC)

Possible Settings: Enable, Disable

Default Setting: Disable

Data scrambling is used to suppress the possible simulation of network-initiated DSU latching loopback commands by application data.

HData Scrambling (64K CC) option appears when Operating Mode is set to DDS in Table A-1.

Enable ± Enables data scrambling. The local and remote units must be set the same.

Disable ± No data scrambling.

V.54 Initiated DSU Loopback

Possible Settings: Enable, Disable

Default Setting: Disable

When enabled, user data is looped back to the network when a V.54 Loop Up sequence is received. The DSU loopback ends when a V.54 Loop Down sequence is detected.

Enable ± DSU loopback can be initiated or terminated by a remote unit sending in-band V.54 Loop 2 Up or Down sequences.

Disable ± V.54 Loop 2 sequences are ignored.
