The RJ21 50-pin Telco receptacle on the AT-TS12T and AT-TS24T
Repeaters is configured as shown in Figure 42.
For a pin-out table and information on attachment accessories, see
Appendix B.
Port Status Indicators
The port indicators on the AT-TS12T front panel provides visual
diagnostic and activity information for network analysis. The AT-TS12T
has a central bank of indicators, as shown in Figure 43.
Each 10BASE-T port supports the following indicator functions with one
dual-color front panel LED per port.
Note
The LEDs do not reflect real-time activity because a data packet is too fast
for the human eye to distinguish on the LED indicator; therefore, the hub
artificially stretches the LED ON time for easier observation.
