DAPTERS
Optional equipment is available to enhance the Xen system. This equipment can be
purchased separately from the system and added as the customer business needs
grow. All these adapters can be installed on the DTU-Type Xen Multiline Terminals.
A Multiline Terminal can have up to three adapters installed at the same time. If
attaching an APR-UA Unit, a CTA-BA Unit, or an HFU-UA Unit, an external power
supply is required. Only
one
power supply is needed even if more than one adapter is
installed.
When an adapter is installed for the first time into a telephone, the base cover on the
Multiline Terminal may have to be modified. The base cover has two access panels
that are removed before the cover can be closed over the adapters to complete
the installation.

To prepare the Multiline Terminal for adapter installation:
1.
Unplug the telephone cord from the terminal.
