Table A-1. System Options (1 of 2)

Operating Mode

Possible Settings: DDS, LADS

Default Setting: DDS

The unit's operating mode depends upon the DSU's application.

DDS ± Standard DDS network operation. The operating rate is either 56 kbps or 64 kbps CC.

LADS ± The Local Area Data Set operating mode requires that the local and remote units are connected directly to each other. This is a point-to-point application; also known as LDM.

DDS Line Rate (Kbps)

Possible Settings: 56, 64CC, Autobaud

Default Setting: Autobaud

The unit starts up with Autobaud. When the DDS line rate obtained from the service provider is detected, Autobaud is replaced with the actual rate.

HDDS Line Rate (Kbps) option appears when Operating Mode is set to DDS.

NOTE: Setting the actual data rate will result in minimum power-up time.

Configuring the actual data rate is recommended after initial installation.

56 ± 56 kbps line rate.

64CC ± 64 kbps Clear Channel on a 72 kbps circuit.

Autobaud ± This setting is automatically changed to the actual operating line rate of 56 kbps or 64CC as soon as the signal is detected.

LADS Timing

Possible Settings: Internal, External, Receive

Default Setting: Receive

Determines the timing source for the unit.

HLADS Timing option appears when Operating Mode is set to LADS.

Internal ± Timing derived from the unit's local clock. Use this setting for the LADS primary timing unit that establishes the timing for both point-to-point units.

External ± Timing is derived from the external clock provided by the DTE connected to the V.35 interface on circuit CT113 (pins U, W).

Receive ± Timing is derived from the line receive signal unless the unit is running diagnostic tests. During the tests, the timing source is the internal clock. This setting should be used for a LADS secondary timing unit.
