¾ To connect E1/T1 trunks using RJ-48c connectors (1-, 2-, 4-, 8-
trunk device) take these 2 steps:
1. Connect the E1/T1 trunk cables to the ports labeled Trunks 1 to 8 (in the case of the
8-trunk device) on the Mediant 2000 RTM.
2. Connect the other ends of the Trunk cables to the PBX/PSTN switch.
RJ-48c trunk connectors are wired according to the figure below.

3.1.4.3 Connecting the Ethernet Interface
TheMediant 2000 provides two 10/100Base-TX RJ-45 ports for connection to the Ethernet
network. The dual ports provide Ethernet redundancy. Follow the procedure below for
connecting to the Ethernet network.
¾ To connect the Ethernet interface, take these 3 steps:
1. Connect a standard Category 5 network cable to the Ethernet RJ-45 port (labeled
ETHERNET).
2. Connect the other end of the Category 5 network cables to your IP network.
3. For Ethernet redundancy/backup, repeat steps 1 and 2 for the second Ethernet port.
When assigning an IP address to the gateway using HTTP (in Section Error! Reference
source not found.), you may be required to disconnect the Ethernet cable and re-cable it
differently.
Note: For Ethernet redundancy, it's recommended to connect each of the Ethernet
connectors to a different switch.
