FXS / FXO / BRI / PRI

Telephony port interfaces that can include one or a combination of the following, depending on the ordered model:

■ FXS port interfaces (RJ-11)
■ FXO port interfaces (RJ-11)
■ ISDN BRI port interfaces (RJ-45)
■ ISDN PRI (E1/T1) port interfaces (RJ-48)

Note:

■ The FXS/FXO interfaces support loop-start signalling (indoor only).
■ For supported hardware configuration options, refer to the Release Notes.

3

GE

Up to four 10/100/1000Base-T (Gigabit Ethernet) LAN ports for connecting IP phones, computers, or switches. These ports support the following features:

■ 1+1 LAN port redundancy: These ports are grouped in pairs, where one port is active and the other redundant. When a failure occurs in the active port, a switchover is done to the redundant port.
■ Half- and full-duplex modes
■ Auto-negotiation
■ Straight or crossover cable detection

4

FE

Eight Fast Ethernet (10/100Base-TX) RJ-45 LAN ports for connecting IP phones, computers, or switches. The supported port features are the same as the GE ports (see Item #6 above).

Note: The Fast Ethernet ports are available only on "pure" SBC Mediant 800 (i.e., without PSTN / Gateway interfaces).

Reset pinhole button for resetting the device and optionally, for restoring the device factory defaults. To restore the device to factory defaults, with a paper clip or any other similar pointed object, press and hold down the Reset pinhole button for at least 15 seconds (but no more than 25 seconds).
