Rear Panel Interfaces - 24 Port I/O

CTRL 0, CTRL 1

Redundant 10/100/1000BaseT Ethernet connectors providing secure communication with an external host or device.

Auto-negotiating, full-duplex connectors that support MDIX (cable crossover), eliminating the need for crossover cables for point-to-point communications.

Base MAC is always assigned to the CTRL interfaces. The IP address assigned to this interface through dhcp or bootup.cfg will be used for OAMP support.

Can be utilized for RTP Traffic and IP Signaling if required. IP addresses must not conflict with the IP address set up through dhcp.conf or bootp.cfg files.

AUX 0, AUX 1

Reserved for future use.

DATA A0, DATA A1 DATA B0, DATA B1

Redundant 10/100/1000BaseT Ethernet connectors providing an interface to the internal Ethernet switch.

Used to communicate to all IMG 2020 devices that communicate over the public network.

Up to 2016 VoIP channels available.

Auto-negotiating, full-duplex connectors that support MDIX (cable crossover), eliminating the need for crossover cables for point-to-point communications.

Interface DATA A is reserved for both RTP traffic and IP signaling.

Interface DATA B is reserved for both RTP traffic and IP signaling.

T1/E1

(24) T1/E1 DS-1's. (RJ48 Connectors)

Up to 768 E1 TDM DS-0's available.

Up to 576 T1 TDM DS-0's available.

Redundancy (1+1 T1/E1 redundancy)

Reserved for future use.

Ethernet LEDs

RJ-48 Ethernet connectors containing one Ethernet status LED:

Green/blinking green - 1000Base-T link present/1000Base-T activity

Orange/blinking orange - 100Base-T link present/100Base-T activity

Power supply LEDs

Indicate the power supply status:

Off = No power to both power supply units.

Flashing red with audible alarm = No power to one of the redundant supplies

Green = AC present. Only standby output on.

Blue = DC power supply on and OK.
