The front panel of the CyberSWITCH has several LED indicators. The POWER indicator will
remain lit while the unit is on. There is a series of three LAN indicators: they will light to indicate
transmissions, receptions, or good link integrity on the 10Base-T port. The bank of WAN indicators
provide you with the status of each WAN line.

The CyberSWITCH has the following LAN indicators: TX, and RX, and 10BaseT. These indicators
convey the state of the communication link between the system and the LAN.

•
10BaseT indicates connection to a 10Base-T LAN. If there is good link integrity on the 10Base-T
port, this light shines steadily. If a connection other than 10Base-T is used (such as an AUI con-
nection) or there is no link integrity, this light will not shine.

The TX indicatory flashes while the system transmits data across the LAN. Note that at least
128 bytes of data must be transmitted to trigger the TX indicator.

The RX indicator flashes while the system is receiving data from another device on the LAN.
WAN LED I

The WAN indicators provide the status of each BRI line. For each BRI line, there is a bank of four
LED indicators. The four LED indicators are labeled as follows: Sync, D-Chan, CH-1, and CH-2.
LED indicators. The four LED indicators are labeled as follows: Sync, D-Chan, CH-1, and CH-2.
•
The Sync indicator identifies whether or not the most basic level of the ISDN connection (Layer
1) is established. It verifies that the system is connected to the ISDN network at this BRI port.
This light must be on for D-CHAN, CH-1 or CH-2 to be operational.

This light must be on for D-CHAN, CH-1 or CH-2 to be operational.

The D-Chan indicator signifies data link and D channel activity. If the data link successfully
initializes, the D-Chan indicator flickers momentarily, then stays lit. When there is a a call, the
D-Chan indicator flickers momentarily, stays lit, and then one of the CH indicators light up. If
there is a second call, the D-Chan indicator will again flicker momentarily and then the other
CH indicator will light up.
