The Ribbon Edge 8300 device features interfaces for analog telephony access:

  • On the front panel, each of the 4 x T1/E1 ISDN PRI interfaces can be enabled or disabled by configuration.
  • On the back panel, each of the 24 FXS/FXO interfaces can be enabled or disabled by configuration.

The FXS/FXO interfaces on the back panel are available in two configurations: either 24 FXS ports, or 22 FXS ports and 2 FXO ports. The ports are not interchangeable: FXS ports cannot be configured as FXO ports or vice-versa. An Amphenol connector (also known as a telco connector) on the back panel provides access to the FXS interfaces. Two RJ-11 ports provide access to the FXO interfaces.

For power, the Ribbon Edge 8300 device offers three types of power supplies: single power supply and redundant AC or DC power supply.

Fans

The fans help the device stay cool. To avoid the device overheating, place the device in an area that allows free airflow in front of the fan vents.

Power Switch

The power switch is used to switch on or off the device or to reset the device. The power and status LEDs on the front panel turn solid green after the device powers on. 

The power switch operates in two modes, depending on the device configuration:

Power Supply TypePower Switch Operation
Single AC power supplyPower On-Off: Press the switch to turn on or turn off the hardware
Redundant AC or DC power supplyPower Reset: Press the switch for 4 - 5 seconds to perform a hardware reset

Redundant AC Power Supply

The redundant AC power supplies are hot swappable and can be removed and replaced without shutting down the device, provided that one of the power supplies is online and working.

An audio alarm sounds if a power supply fails or is missing. Press the black button on the right side of the PSU cage to silence the alarm.

Analog Ports

The 8300 supports two analog port configurations on the back of the chassis:

  • 8300-24S: 24 FXS ports
  • 8300-22S-2X: 22 FXS ports and 2 FXO ports

When present, the FXO interfaces appear as a pair of RJ-11 ports.

The FXS ports connect using a 50-pin Amphenol connector (also known as a telco connector), which can be wired to a breakout panel. Order the optional breakout panel and cable from Ribbon using the following codes:
