NFORMATION
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 adaptors can be installed on the
DTU-Type Xen Multiline Terminals.
A Multiline Terminal can have up to three adaptors installed at the same
time. If attaching an APR-UA Unit, a CTA-UA Unit, a CTU( )-UA Unit, VDD-
UA Unit or an HFU-UA Unit, an external power supply is required. Only one
power supply is needed even if more than one adaptor is installed.
When an adaptor 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 adaptors to complete the installation.
