1STM4 (1-Port 622M Packet over SDH/SONET Optical Interface Card)
Card Overview
The 1STM4 is a high-speed MAN and WAN access module that provides 622 Mbit/s connection to a synchronous digital hierarchy (SDH) network. A 1STM4 card can be installed in a WSIC slot of a router.
Figure 7-157 shows the appearance of a 1STM4 card.
