4STM1 (4-Port 155M Packet over SDH/SONET Optical Interface Card)
Card Overview
The 4STM1 is a high-speed WAN access module. Normally, a 4STM1 card provides 155 Mbit/s bandwidth on all the four interfaces for connection to a synchronous digital hierarchy (SDH) network. You can set the bandwidth on interface 0 to 622 Mbit/s by disabling interfaces 1-3. 4STM1 cards are often used for MAN or WAN connection.
A 4STM1 card can be installed in a WSIC slot of a router.

Table 3 Indicator description
Number | Indicator | Color | Description |
1 | STAT | Green | Slow blinking: The system is running properly. Fast blinking: The system is being powered on or restarting. Steady on: The card has been powered on, but the software is not running. |
Red | Steady on: A fault that affects services has occurred and cannot be rectified automatically. The fault needs to be rectified manually. | ||
Orange | The card has been properly installed and detected by the system. | ||
2 and 3 | SFP interface indicators: 2: LINK indicator 3: ACT indicator | Green | LINK indicator steady on: A link has been established. |
LINK indicator off: No link is established. | |||
Yellow | ACT indicator blinking: Data is being transmitted or received. | ||
ACT indicator off: No data is being transmitted or received. |
