Table A-3. Data Port Options (1 of 3)

Invert Transmit Clock

Possible Settings: Enable, Disable

Default Setting: Disable

The DSU clock provided on Interchange Circuit CT114, Transmit Signal Element Timing DCE source (TXC), is phase inverted with respect to Interchange Circuit CT103, Transmitted Data (TXD). Recommended when data errors are occurring due to long cable lengths.

Enable ± The DSU-supplied clock is phase inverted with respect to TXD.

Disable ± The clock supplied by the DSU on TXC is normal (i.e., not inverted).

Port (DTE) Initiated Loopbacks

Possible Settings: Disable, Local, Remote, Both

Default Setting: Disable

Specifies whether the DTE can initiate and terminate local and/or remote loopbacks.

The DTE loopback control is done through the Interchange Circuits specified by the

V.54 standard.

NOTE: Refer to Loopbacks in Chapter 7.

Disable ± No local or remote loopbacks can be initiated by the DTE.

Local ± A local loopback can be controlled by the DTE, via the Interchange Circuit LL (CT141), as specified by V.54. The DTE port remains in loopback as along as LL remains on. Aborting the loopback from the ATI has no effect.

Remote ± A remote digital loopback can be controlled by the DTE, via Interchange Circuit RL (CT140), as specified by V.54. The remote equipment must be able to detect the in-band V.54 loopback sequence.

Both ± Both the local and remote loopbacks can be controlled by the DTE.

Bilateral Loopback

Possible Settings: Enable, Disable

Default Setting: Disable

When a DSU loopback is initiated, a local DTE loopback is also automatically initiated. A Bilateral Loopback can be started by the ATI/NMS or by detection of a V.54 Loop 2 Up sequence.

Enable ± When Bilateral Loopback is enabled, running a DSU loopback also automatically starts a local loopback. The local loopback ends when the DSU loopback terminates.

Disable ± Running a DSU loopback does not start a local loopback.

NOTE: Refer to Loopbacks and Network Tests in Chapter 7.
