Direct Inward Dialing (DID)
Strata CTX General Description 10/04 67
Direct Inward Dialing (DID)
System Availability: All systems
This feature allows external callers to dial directly to individual extensions or groups of telephones
without intervention by an operator, IVR or auto attendant. Each incoming DID number, which is
sent to the CTX on a DID line from the CO, can be routed individually to an extension, pooled or
group line button, ACD group, maintenance modem, external page, night bell, voice mail box, or
back out over the public or private telephone network. DID routing assignments can change
automatically when the system switches between the Day and Night Modes.
DID numbers can vary between 1~7 digits in length for each DID line group. Each DID number
can be assigned to 1 of 15 possible music-on-hold sources.
DID service is provided by DID analog, T1, or ISDN line interfaces.
Dialed Number Identification Service (DNIS)
System Availability: All systems
DNIS lines receive 800- and 900-type telephone calls that provide the number the caller dialed to
reach the Strata CTX. The Strata CTX translates the DNIS number into a name that displays on the
telephone’s LCD. This allows the user to identify where the call is coming from and the purpose of
the call before the call is answered.
The DNIS Name/Number routes calls to specific telephones, departments or ACD groups. When
the call is ringing and after it is answered, the DNIS Name/Number displays on the telephone’s
LCD. The name and number display can also be sent to an agent computer to be used by a CTI
application.
Applications include sending DNIS calls to a group of agents that take orders for a number of
different companies and products. The agents know how to answer the calls from the DNIS
display. Using DNIS capabilities allows one group of lines to be used to serve multiple
applications. DNIS service is provided by DID analog, T1 or ISDN line interfaces and provides the
same call routing options and destinations as DID calls.
Digital Pad
System Availability: All systems
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
