Table 4-13. CSU/DSU Data Port Physical Interface Options (1 of 2)

Port Type (9788)

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

Default Setting: V.35

Determines the configuration of the data port.

E530 – The port is configured as an EIA-530-A-compatible DCE. An EIA-530-A- compatible DTE may be directly connected to the DB25 connector for the port.

V.35 – The port is configured as a V.35-compatible DCE. A V.35-compatible DTE may be connected to the port using a DB25-to-MS34 adapter.

X.21 – The port is configured as an X.21-compatible DCE. An X.21-compatible DTE may be connected to the port using a DB25-to-DB15 adapter.

Invert Transmit Clock

Possible Settings: Auto, Enable, Disable

Default Setting: Auto

Determines if the FrameSaver unit clock on interchange circuit DB (ITU 114) – Transmit Signal Element Timing (DCE Source) TXC is phase inverted with respect to the clock used to time the incoming Transmitted Data (TD).

Auto – The port will check the clock supplied by the DCE on TXC on this port. If necessary, the port will automatically phase invert the clock with respect to the transmitted data.

Enable – Phase inverts the TXC clock. Use this setting when long cable lengths between the FrameSaver unit and the DTE are causing data errors.

Disable – Does not phase invert the TXC clock.
