A 4E1 interface card provides four balanced-output ports. If the TE60 has a 4E1 interface card
installed, connect the TE60 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 TE60.
For safety reasons, insert the interface card only when the TE60 is powered off.

Do not connect outdoor cables directly to the TE60. 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
E1/T1 Grounding Criteria.
