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.

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.
