Serial I/O Connector
V.35 Supported Signals
This configuration supports the V.35 standard in a DTE format. The V.35 standard is also
supported through a hydra cabling option. Table 5-6, “V.35 Signals and Pins,” shows the
supported signals and their positions on the dual VHDCI connector.
Note: Some of the pins on the connector may not be included in the table. For each electrical
standard, the pins that are not included in the table for that standard MUST BE LEFT
UNCONNECTED.
