3.2 Connecting to a 4E1 Network
Only the TE80 supports 4E1 functions. To implement video communication over a 4E1-line
dedicated network, you must connect the TE80 to the network.
 Do not connect outdoor cables directly to the TE80. If outdoor E1 lines (unbalanced) are
led indoors, surge protectors are required. Any questions, contact technical support
personnel.

The connection of E1 lines must comply with grounding specifications. For details, see A
E1 and T1 Grounding Criteria .
A 4E1 interface card provides four balanced-output ports. If the TE80 has a 4E1 interface card
installed, connect the TE80 to a 4E1-line dedicated network.
The ports of a 4E1 interface card can be used for any of the four E1 lines. There is no
mapping between the ports and the four E1 lines on the local and the remote ends, so the lines
can be connected to any of the ports at the local and remote ends, as long as all the four lines
are connected.
3.2.1 Inserting a 4E1 Interface Card
To hold conferences over a 4E1 network, you must insert a 4E1 interface card into the
corresponding interface slot at the back of the TE80.
For safety reasons, insert the interface card only when the TE80 is powered off.
Figure 3-1 shows the appearance of a 4E1 interface card, for your reference only.
