OPTIONAL PHONE ADAPTERS
Using Adapters (Figure 4-18)
Each Aspila EX system phone can have two
optional adapters installed (unless an IP
adapter is used). These adapters provide the
system phones different capabilities, depend-
ing on the adapters installed.
• ADA - Conversation Recording
• APA - Analogue Port Adapter Without
Ringer
• APR - Analogue Port Adapter with
Ringer
• CTA - Serial Interface (RS-232C)
• CTU - USB Interface
• IP - VoIP Connection
• 24-Button DLS Console (refer to page 4-
10 for complete details on connecting the
DLS)
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 a 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 system phone 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 accom-
modate the adapter(s).

1 = The IP Adapter takes the full space provided for adapters on the system
phones. 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 system phone.
3 = As there is only one voice path provided for adapters, the APR and APA
adapters can not both be used on the same system phone.
4 = Due to protocol collision, the CTU and CTA adapters can not both be used
on the same system phone.
