DDS Network Interface

FrameSaver Models 9623 and 9626 have a DDS network interface.

Table 3-9. DDS Network Physical Interface Options (1 of 2)

Transmit Timing

Possible Settings: Internal, Receive

Default Setting: Receive

Specifies the unit’s timing source based upon how the unit will be used. When the unit is connected to a DDS (Digital Data Service) network for standard operation, timing is provided by the network. In a LADS, or LDM, application (local area data set/limited distance modem), where local and remote FrameSaver units are directly connected, one of the units provides timing for both units.

Internal – Timing for the unit and its attached LADS partner is derived from the unit’s internal clock. Use this setting when the unit will be used as a LADS primary timing unit, where the FrameSaver unit establishes overall timing for the two interconnected units.

Receive – Timing for the unit is derived from the network Received signal. Use this setting for standard DDS operation, or when the unit will be used as a LADS secondary timing unit. See DDS Line Rate (Kbps).

DDS Line Rate

Possible Settings: Auto_On_No_Signal, Initialize_From_Network, 56, 64CC

Default Setting: Auto_On_No_Signal

Configures the network interface’s line speed to match the Digital Data Service’s (DDS’s) line speed. This is the rate at which data is transmitted over the DDS line.

Display Conditions – This option only appears when Transmit Timing is set to Receive.

Auto_On_No_Signal – Automatically detects the line rate on the network interface whenever a No Signal alarm is declared, the unit is reset, or the line rate is changed to Auto_On_No_Signal and saved, then changes the unit’s operating rate to match the network’s. It may take up to 15 seconds each time automatic rate detection and adjustment occurs.

Initialize_From_Network – Automatically detects the line rate on the network interface once, then changes the unit’s operating rate to match the network’s. Automatic rate detection and adjustment, or Autobaud, will not occur again unless the line rate is changed to Initialize_From_Network or Auto_On_No_Signal and saved. It may take up to 15 seconds for automatic rate detection and adjustment to occur.

56 – Forces the line rate to 56 Kbps.

64CC – Forces the line rate to 64 Kbps Clear Channel (72 Kbps on the line).
