ShoreGear-24 Voice Switch
The ShoreGear-24 (IPBX-24) (Figure 6-6) supports 24 analog ports in a combination of

ShoreGear-24 ports to IP phone support before attempting to install and
configure IP phones.

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 Central
Office.
• When flashing yellow, the frame-bit error rate has exceeded its limits.
• When flashing slow yellow, a small number of frame-bit errors
(10e
-6
) have occurred; this state will take up to 10 minutes to clear.
• When flashing fast yellow, a series of frame-bit errors (10e
-3
) have
occurred.
• When red, the T1/E1 signal is out-of-frame (OOF). The received
