Toshiba Strata CTX100 User Manual

The Strata CTX digital pad (decibel loss) is activated for the receiving path of the terminal, 
external line or resource.

The system adjusts for differing transmission levels between internal and external devices. This is 
very useful for conference calls when external parties have difficulty hearing due to public 
network loss. The Strata CTX can be programmed to insert the appropriate digital pad for each 
terminal and call type when establishing speech paths between telephones, external lines, and 
resources such as conference circuits, external paging devices, and external sound sources. This 
minimizes volume loss in conference calls. 

The system recognizes these devices:

•

Standard analog telephone (Type 500, Type 2500 and the equivalent) 

•

Toshiba digital telephone, cordless, wireless, door phone

•

Analog trunk

•

T1 trunk

•

ISDN extension terminal (Audio and Speech) 

•

ISDN trunk/Tie line (Audio and Speech) 

•

•

•

External paging device

Direct Inward System Access (DISA) allows outside callers to connect to the Strata CTX and 
make station or trunk calls as if they were stations within the system. An incoming call may be 
directed to DISA by Direct Inward Dialing lines, ground/loop start lines or Automated Attendant.

DISA lines require DTMF receivers.

DISA security code is changeable from a specific station. The station to change the security code 
needs to be allowed by Class of Service. This security code can also be changed using the Strata 
CTX WinAdmin administration console.

DISA provides access to the features listed below:

•

Station Calls

•

Station Calls over Private Network
