G.18.1.2 Network LEDs
Network LEDs indicate the speed at which the switch is communicating with the network
and when there is network activity. The network LED descriptions follow:
Link: This LED indicates that the switch is connected to an Ethernet network.
100M
When lit, the switch is connected to a 100BaseT network.
When off, the switch is connected to a 10BaseT network.
Traffic: This LED indicates network activity, as follows:
When flashing, network activity is detected.
When on (not flashing), heavy network activity is detected.
When off, network activity is not detected.
This LED is not directly related to any particular switch’s individual network
activity. For example, if you have three switches connected to the same hub, and
one switch’s Traffic LED shows activity, the other switches will indicate the same.
G.18.1.3 T1 and E1 LEDs
The T1 and E1 LEDs indicate line coding, network framing, and loopback status. These
LEDs are color coded—green, yellow, and red. T1 and E1 LED alarms and errors are logged
as switch events in ShoreWare Director’s event log.
Line Coding: This LED indicates line coding status, as follows:
When green, the line coding signal is good.
When yellow, bipolar violations (BPV) are detected one second intervals.
When red, a loss of signal (LOS) has occurred.
When off, the switch has no power.
Framing: This LED indicates network framing status, as follows:
When green, the T1/E1 signal is in frame; the signal is synchronized.
When yellow, a yellow alarm has been received from the CO.
When flashing yellow, the frame-bit error rate has exceeded its limits.
When flashing slow yellow, frame-bit errors (>1 per million) have occurred; this
state will take up to 10 minutes to clear.
When flashing fast yellow, frame-bit errors (>1 per 1000) have occurred.
When red, the T1/E1 signal is out-of-frame (OOF). The received signal cannot
be framed to the Extended Superframe (ESF) or D4 format.
When off, the switch has no power.
Loopback: This LED indicates loopback status for testing, as follows:
When yellow, loopback is enabled. This may be set from within ShoreWare
Director or from the CO.
When off, loopback is disabled.
G.18.2 IPBX-T1 and IPBX-E1 Connectors
The IPBX-T1 and IPBX-E1 voice switches contain the following components:
1 DB-9 female connector for maintenance
1 RJ-45 connector for the LAN interface
1 RJ-48C connector for T1 or E1 monitoring
1 RJ-48C connector for the T1 or E1 interface
