Mediant 1000
H.323 User's Manual 38 Document #: LTRT-83401
• Digital interfaces: Connect the E1/T1 trunk cables to the ports on the digital I/O
module/s. Connect the other ends of the trunk cables to your PBX/PSTN switch.
For a 1+1 or 2+2 fallback option, connect trunks 1 and 3 to your PBX, and trunks
2 and 4 to the PSTN. If the power fails, a relay connects trunks 1 to 2 and 3 to 4
(in the same module) acting as a fallback for PSTN trunks. RJ-48c trunk
connectors are wired according to the figure below.

3. Connect the first Ethernet connection (labeled I), located on the CPU module of the
Mediant 1000 front panel, directly to the network using a standard RJ-45 Ethernet
cable (and the second connection as optional redundancy / backup). Note that for
redundant operation it is recommended to connect each of the Ethernet connectors to
a different switch. For the connector’s pinouts, refer to the figure below.
When assigning an IP address to the Mediant 1000 using HTTP (under step 1 in
Section 4.2.1), you may be required to disconnect this cable and re-cable it differently.

4. Optionally, connect the Mediant 1000 RS-232 port to your PC (refer to Section 3.4.1
on page 38). The RS-232 port is used to access the CLI (Section 4.2.4 on page 50)
and to receive error / notification messages.
5. If you want to set up a dry contact system, refer to Section 3.4.2 on page 39.
6. Connect the left (active) 100-240V~50-60 Hz power socket to the mains using the
supplied cord. For detailed information on the power supply module, refer to Section
2.1.3 on page 30.
3.4.1 Connecting the Mediant 1000 RS-232 Port to Your PC
Using the supplied cross-over RS-232 cable (shown in Figure 3-4) connect the Mediant
1000 RS-232 port (Labeled I0I0) to either COM1 or COM2 RS-232 communication port on
your PC.
For information on establishing a serial communications link with the Mediant 1000, refer to
Section 11.2 on page 297.
