Vanguard Managed Solutions 7300 Series Serial Card, Type DTE Cable Plug DCE Cable Socket

	Cabling Procedures
Serial Card
Introduction
	All cabling for the Serial card is done at the rear of the chassis on the 8-port rear
	panel shown in Figure 3-28.The eight ports support up to eight channels of serial
	data for WAN networking and telecommunications applications.

Each Serial card port can be software configured for synchronous serial communication protocol. Software-configurable baud rates range from 1.2Kbps to 8Mbps. For software configuration procedures, refer to Chapter 4, Operating Your Vanguard 7300.

Cabling the Serial Due to the high traffic density of this board, the following interface-specific cables

Card	are required with these characteristics:
	• Serial card cables have a fixed length of seven feet
	• Separate Data Terminal Equipment (DTE) and Data Communications
	Equipment (DCE) cables are required because DTE/DCE operating mode is
	determined by the physical cable characteristics
	This table lists the cables available for use with the Serial card:
