3. Configuration Options

Table 3-12. SHDSL Network Physical Interface Options (2 of 2)

PSD Mask

Possible Settings: Symmetric

Default Setting: Symmetric

Read-only. Specifies the Power Spectral Density (PSD) mask the unit will use. The value of PSD Mask in part determines what DSL Line Rates are available. If a change in the PSD Mask setting (available in a future release) renders the current DSL Line Rate invalid, the Line Rate Mode is set to AutoRate.

Asymmetric – (Future use.) The unit uses the asymmetric PSD mask.

Symmetric – The unit uses the symmetric PSD mask.

Synchronous Network Interface

FrameSaver Models 9820-2M and 9820-8M have an EIA-530-A network interface.

Table 3-13. Synchronous Network Data Port Physical Interface Options (1 of 2)

Port Type

Possible Settings: E530, V.35, X.21

Default Setting: V.35

Selects the type of port to be used for the network data port.

E530 – The port is configured as an EIA-530-A-compatible DTE. An EIA-530-A-compatible DCE can be directly connected to the DB25 connector for this port on the rear of the FrameSaver unit.

V.35 – The port is configured as a V.35-compatible DTE. A V.35-compatible DCE can be connected to the DB25 connector for this port using an adapter cable on the rear of the FrameSaver unit.

X.21 – The port is configured as a V.11/X.21-compatible DTE. A V.11/X.21-compatible DCE can be connected to the DB25 connector for this port using an adapter cable on the rear of the FrameSaver unit.

Invert Internal Clock

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether the internal clock (used for timing data transmitted to the DCE) will be phase-inverted with respect to the clock received at the interface. This option is useful when long cable lengths between the FrameSaver device and the DCE are causing errors.

Enable – The internal clock used to transmit data to the DCE is phase inverted with respect to the clock supplied by the DCE to this port.

Disable – The internal clock is not inverted (normal).
