Matrix ETERNITY NE System Manual 297
Access Codes
What's this?
Access codes are short digit sequences dialed from an extension phone to instruct the PBX to perform a function
such as:
• Calling an extension.
• Calling a group of extensions (“Department Call”).
• Grabbing a trunk line or any trunk line from a group of trunks.
• Turning on/off Digital Output Port.
• Invoking a feature. Activating or deactivating a feature.
Accordingly Access Codes are classified into:
• Station Codes: Codes used for calling DKP, SLT, SIP extensions, Digital Output Port, Door Phone. These
codes are also commonly referred to as Extension numbers.
Default station codes are:
• SLT extensions: 201 to 214
• DKP extensions: 301 and 302
• SIP extensions: 303 to 318
• Door Phone: 215
• Logical Group Codes: codes used for calling a group of extensions as in a Department group, a group of
trunks.
Default logical group codes:
• Department groups: 391 to 395
• Trunks access codes: 0, 5, 61, 62, 63, 64
• Feature Codes: codes used for invoking a feature.
Default feature codes: there are different feature codes for every feature and function of the ETERNITY
NE. For example, '2' for Auto Call Back, '5' for Raid, '13' for Call Forward.
Access codes may consist of single digits or a sequence of a maximum of 6 digits.
You can change the default access codes to the codes of your choice. For example: the default Operator
code '9' can be changed to '0'.
How it works
Whenever an access code is dialed from an extension, the system matches each digit in the code with the access
codes configured within the system to determine the instruction, like whether it is an extension it must call, or a
trunk line it must grab, a port it has to activate. The system processes the instruction when a match is found.
