Matrix ETERNITY NE System Manual 575
Access Codes
Access codes are short digit sequences dialed from an extension phone to instruct the System 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.
• Invoking a feature. Activating or deactivating a feature.
Accordingly Access Codes are classified into:
• Extension Codes: Codes used for calling SLT and SIP extensions. These codes are also commonly
referred to as Extension numbers.
Default Extension codes
93
are:
• SLT: 21 to 22
• SIP: Blank
• 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 and 5
• Feature Codes: Codes used for invoking a feature.
Default feature codes: there are different feature codes for every feature and function of SARVAM UCS.
For example, '4' for Barge-In, '5' for Raid, '13' for Call Forward.
Access codes may consist of single digits or a sequence of a maximum of 6 digits.
You may change the default access codes, if required. 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.
For example:
• An extension user dials 131 to set Call Forward.
• When the first digit '1' is dialed, the system finds a match. As several default access codes begin with '1'
the system waits for the next digit to be dialed.
• When the second digit '3' is dialed, the system finds a match for '13'.
