Serial Card and Rear Transition Module
Introduction
The Serial Card and its Serial Rear Transition Module support multi-protocol high-
speed serial data communications. The Serial Card and transition module support up
to eight channels of serial data. They are typically used for LAN/WAN networking
and telecommunications applications. Like the T1/E1/PRI card, the two-part Serial
Card shown in Figure 2-23 occupies a single Vanguard 7300 chassis slot.
