System Configuration

The system uses advanced digital interface technology. One cable pair supports up to four digital telephone endpoints. Each digital telephone endpoint has its own extension number and can be called from any other extension in the system.

Xblue Networks X16 Office Phone System Description

Businesses can benefit from a robust and flexible communication solution with the xblue Networks X16 Office Phone System. The X16 makes it easy to access important features and operations with its 5-inch color display and 16 configurable keys. The 100-hour backup battery guarantees ongoing communication during power outages, and the built-in Bluetooth and Wi-Fi features make it easy to integrate with mobile devices. Businesses of all sizes will find the X16's advanced security features and support for up to sixteen extensions to be an ideal fit.

Installation

The X16 comes standard with four RJ11 extension ports. Each port supports up to 4 proprietary digital telephone endpoints, for a total of sixteen (16) endpoints. Each port on the system will support up to 600 feet of cable. In a star topology, 600 feet is calculated by adding each Digital Telephone endpoint's cable run. Cable A + Cable B + Cable C + Cable D <= 600 feet. In a serial cable topology, 600 feet is calculated by adding the distance of the initial run plus the distance between each telephone. Cable A to telephone 1 + (distance between telephone 1 & telephone 2) + (distance between telephone 2 & telephone 3) + (distance between telephone 3 & telephone 4) <= 600 feet.

Location
The system should be located close to the telephone company interface (RJ21X), and have a dedicated outlet with an isolated ground. The system can be mounted on the wall or placed on a table. Once the location of the system is determined, use the supplied wall mounting template to level and secure the system with the provided screws, or place it on a table.
Line up the back of the system with the four screws, and slide it into place.
CO Line Connections
Using the matrix below, connect the CO Lines to the system using one RJ14 connector per CO Line. The port labeled Line 1 is a direct access auxiliary port for line 1 allowing an analog device direct access.
Line Port Number Connection
AUX CO Line1 CO Line 1 1 / 2
CO Line 2 CO Line 2 2
CO Line 3 CO Line 3 / 4
CO Line 4 CO Line 4
CO Line 5 CO Line 5
CO Line 6 CO Line 6
Telephone Endpoint Connection
Connect telephone endpoints to the system using one RJ11 port for up to 4 different endpoints, with a maximum of 600 feet per port. Once connected, each telephone endpoint will register with the voice server when it is powered up. At default, the extensions begin with number 301. The remaining extension numbers must be entered.
Correct Installation Process
It is important to connect a telephone to every jack that is connected to the system. Extensions connected to a cable with “Bridge Taps” may experience distortion. If locating a bridge tap is not practical, a quick resolution is to use a different cable pair such as the Yellow/Black or White/Orange.
Incorrect Installation Process DO NOT leave any ports open
X16 Cable Pair
Leaving any ports punched down but not connected to a telephone may result in erratic operation. When mounting a Digital Telephone Endpoint, be sure to use the inner posts on an adjustable wall mount plate.
Punch Down
In this example, system ports 10 through 16 do not have telephones connected to them but they are still “punched down” on the system. There is a potential that extensions, especially extension 309 in this example, may experience distortion.
Power up and Initialization
Connect the power to power on the system. To initialize the system, once the blue LED begins flashing at 1 impulse per second (IPS), switch the “init switch” back and forth three times and the LED will begin flashing at a rapid rate for 5 seconds and then return to 1 IPS. For proper operation, be sure to reset, by unplugging, the system after all extensions are connected.
Extension Numbering of X16 Office Phone System
One extension will automatically be numbered 301; all other extension numbers will have to be entered at the time of installation. Valid numbers are 302 to 399. The system becomes fully functional after all extensions are registered. Extensions may be moved from one port to another simply by unplugging the unit and plugging it into another active port. If the extension is unplugged for longer than 120 seconds (2 minutes), the port may initialize and revert back to factory default – This includes all personal voice mail settings. Any port that is active must have either a telephone or an Endpoint Device connected to it, or distortion may be heard.

Line Port Number	Connection
AUX CO Line1	CO Line 1 1 / 2
CO Line 2	CO Line 2 2
CO Line 3	CO Line 3 / 4
CO Line 4	CO Line 4
CO Line 5	CO Line 5
CO Line 6	CO Line 6

Note: An “Endpoint Device” may be needed when relocating an extension.

Expansion Module

The X16 system comes with four CO Lines and is expandable to six CO Lines. The two-line expansion module can be either a CO Line module or a two-channel VoIP Gateway Module. The expansion module mounts inside the communication server and connects to the main board via ribbon cable. When the system is powered on, the expansion module will be recognized in software and fully operational. Use the following steps to install the expansion module.

Installing the Expansion Module
- Place the voice server face down on a stable surface such as a table, showing the four rubber feet.
- Remove the four rubber feet, placing them in a safe place, such as the back of the voice server, exposing 4 screws. Unscrew the four screws and remove the cover.
Insert the Expansion Module
- Remove the plastic tab found on the front of the Voice server. Insert the RJ14 (RJ48 for VoIP) connections through the front of the voice server and secure the card with the provided screws. Connect the ribbon cable from the expansion module to the main board and replace the cover. Place the provided black plastic encasement window around the newly installed card.

Endpoint Device

Every live telephone jack connected to the system will receive a data signal. If the system finds an open jack (bridge tap), the data signal may be lost, causing the remaining digital telephone endpoints to receive erroneous data, which may lead to improper operation. Therefore, for proper operation, each live telephone jack connected to the system must have either a digital telephone endpoint or an endpoint device.

Symptoms of an open jack include – but are not limited to – voice distortion, static, slow speakerphone reaction when the button is pressed, problems accessing CO Lines, etc.

X16 Office Phone System Programming

The system has two areas of programming; Phone (extension) and System. The system programming parameters affect the whole system, whereas the Phone programming parameters will only affect the extension that is doing the programming.

From an Idle telephone press the program button.
The navigation keys are used to select the area of programming to be modified, Phone or System Setup.

Extension parameters such as voicemail will remain for up to 120 seconds when an extension is unplugged or being relocated. To relocate an extension simply unplug it and plug it into another extension port.

Note: Extension will appear busy to all other extensions when they are in Programming or reviewing caller ID.

Answering Machine Emulation (AME)

This feature “Mimics” the call screening feature of an answering machine. Five seconds after a call is answered by an extension user’s voice mailbox, that user can monitor/screen the caller as they leave a message. The extension user will receive a warning tone, which indicates that a caller has been answered by their voice mailbox. The user has the option to monitor the call or ignore the alert and allow the caller to leave a message. Once the user has selected to monitor the caller, they have the option to leave the caller undisturbed (leaving a message) or to retrieve the caller from the voice mailbox and be connected to the caller for a live conversation.
