IMACS Data Modules and Applications

The IMACS supports multiple user cards for transport of digital data. A list of all cards/model types that can be used in the chassis is provided in Table 13.

Table 13—Data Card Types

Type of Card	Description
820260 HSU Card	Supports two RS530/V.35 or RS-449 data ports via DB25 female connectors. It can
	also support RS232 data through the use of the appropriate Personality module.
	Supports 56K, 64K and Nx56/64K data applications.
820360 HSU Card	Supports two V.11/X.21 data ports which connects to RS530 or X.21 CPE devices via
	DB25 female connectors. The ports may be configured as user ports, or can be used as
	externally clocked network interface ports. Supports 56K, 64K and Nx56/64K data
	applications.
821260 HSU Card	Supports two V.35 synchronous data ports via two DB25 female connectors. Supports
	56K, 64K and Nx56/64K data applications.
821360 HSU Card	Provides two miniature DB26 female connectors. Each port can be configured to
	support RS530 or V.35 devices. Interface selection is made on a port-by-port basis.
	The 8213 supports V.25bis dialing commands (an in-band dialing protocol) and RS-
	366 dialing through the use of separate DB15 pin RS-366 port connectors on the rear
	of the card. Supports 56K, 64K and Nx56/64K data applications.
821460 HSU Card	Supports two V.35 synchronous data ports via two DB25 female connectors. The
	ports can be configured as user ports, or be used as externally clocked network
	interface ports. Supports 56K, 64K and Nx56/64K data applications.
821560 HSU Card	Provides four miniature DB26 female connectors. Each port can be configured to
	support RS530 or V.35 devices. Interface selection is made on a port-by-port basis.
	Supports 56K, 64K and Nx56/64K data applications. Can also support RS232 data at
	56Kbps through the use of the 1253xx Personality Module and 1240 cable layer. The
	821570 HSU card has improved clock jitter performance.
821660 HSU Card	Provides four miniature DB26 female connectors. Each port can be configured to
	support RS530 or V.35 devices. Interface selection is made on a port-by-port basis.
	Supports 56K, 64K and Nx56/64K data applications. Can also support RS232 data at
	56Kbps through the use of the 1253xx Personality Module and 1240 cable layer.
	Supports tail circuits greater than 24 timeslots. V.35 interface compatible with
	international standards, and individually selectable transmit/receive clock inversion
	options.
