The Crystal 104 NEXA is a telecom security software system designed to manage and secure telephone communications. It operates in both Tone and DTMF modes, allowing for versatile integration into existing telephone infrastructures. The system supports up to four extensions, with default extension numbers 1, 2, 3, and 4. Junction access is granted via '0', and direct extension dialing can be achieved using '#1', '#2', '#3', or '#4'.
To make an internal call, users simply lift the handset, dial the desired extension number (X), and begin talking when the other party answers. A dial tone confirms readiness, and a ring back tone indicates the call is connecting. If the dialed extension is busy, a busy tone will be heard, and users can either hang up and try again or utilize the "Auto Call Back" function.
For external calls, users lift the handset, dial '0' to access a junction, followed by the outside number. A junction dial tone indicates successful access, and a ring back tone signals the call is connecting. Similar to intercom calls, a busy tone after junction access means the line is occupied, prompting users to hang up or use "Auto Call Back."
When an extension rings, users lift the handset to answer and begin conversation. A ring tone indicates an incoming call.
The system allows any extension to pick up a ringing call, whether it's an intercom or trunk call. To do this, users lift the handset, dial '*4', and connect to the calling extension. Priority is always given to incoming call rings. Simultaneous and auto-callback rings on an extension cannot be picked up by another extension.
For selective pickup of intercom or trunk calls, users lift the handset and dial '*76+#X', where 'X' is the ringing extension number.
Calls can be transferred either during a conversation (consultative transfer) or without consulting the other party (blind transfer).
This feature allows users to switch between their current call (intercom/junction) and a second call on hold. While talking with a caller, users press the Flash Key (or Hook switch), dial the extension/junction number, and begin conversation with the second party. To toggle back, they press Flash + Dial 1.
If a dialed junction or extension is busy, the system can automatically call back when the line becomes free. Users lift the handset, dial the desired junction/extension number, and during the busy tone, dial '75'. A confirmation tone indicates the auto-callback is set.
This feature is useful for frequently used extensions or junctions. Users lift the handset and dial '*161+X', where 'X' is the extension number. The system will automatically dial the programmed extension after a set delay (default 3 seconds). To cancel a hotline, users lift the handset, dial '*160', and receive a confirmation tone.
This feature protects against unauthorized outgoing trunk calls from an extension.
Users can forward all calls to another pre-assigned extension, useful when moving to a different location.
The Crystal 104 NEXA operates in V-1.0. All system programming must be done in Main Password mode from any extension, using either Tone or DTMF mode. The user guide provides detailed step-by-step procedures for each function, including the specific tones heard (e.g., Dial Tone, Ring Back Tone, Busy Tone, Confirmation Tone, Beep-beep tone, Junction dial tone) and abbreviations for clarity. The system's design emphasizes ease of use with features like Flash Key for call management and specific codes for various functions. The default password for dynamic lock is 1111, and the default hotline delay timer is 3 seconds, which can be adjusted via the programming manual.
