NEC Aspire Product Description page 15

The following chart indicates if there are restrictions when combining certain adapters. Select the
adapter in the column and then select the adapter in the row to see if there are any restrictions. For
example, using an APA and APR adapter refers you to restriction 3 (only one voice path provided -
adapters can not be used together).
When installing the adapters, the keyset should first be unplugged from the system. Also note that
the adapters may have an AC/DC power jack. Power is not required for all the adapters. You should
refer to the information for the specific adapter to determine whether a power source is needed.
Telephones with any of these adapters installed cannot be wall-mounted. The bracket will not
accommodate the adapter(s).

1 = The IP Adapter takes the full space provided for adapters on the keysets.
Therefore, if an IP adapter is installed, no other adapters can be used.
2 = Only one adapter of the same type can be used on a keyset.
3 = As there is only one voice path provided for adapters, the APR and APA
adapters can not both be used on the same keyset.
4 = Due to protocol collision, the CTU and CTA adapters can not both be used
on the same keyset.
