Matrix ETERNITY NE - The CO Interface; The Mobile Interface

Matrix ETERNITY NE System Manual 7
The Interfaces
The ETERNITY NE supports the following interfaces for connecting to different telecom networks, digital key
phones, standard telephones and external devices such as a Door Phone and a Door Lock release.
The CO Interface
The CO Interface enables the ETERNITY NE to be connected to the PSTN Network. The PSTN Networks across
the world support various standards and differ in features. For example, some networks support Caller ID
Presentation using DTMF signaling, while some support Caller ID Presentation using FSK signaling; some
networks offer 600 Ohms Impedance, while others offer complex impedance.
The versatile architecture of ETERNITY NE allows it to be connected to such networks differing in their
characteristics.
The CO Interface supports following features:
• Programmable AC Impedance - 600, 900 and various complex impedances.
• Answer Supervision/Polarity Reversal
• Selectable Disconnect Supervision - Polarity Reversal, Open Loop Disconnect
• Selectable Caller ID Presentation - DTMF, FSK
• Programmable Dialing method - Pulse/Tone (with programmable Pulse Ratio/DTMF On-Off period)
• Programmable Speech Tx Gain
• Programmable Speech Rx Gain
• Programmable Disconnect Tone Sensing
• Programmable Flash Timer
• Programmable Loop Current
The Mobile Interface
The Mobile Interface enables the ETERNITY NE to be connected to GSM/UMTS network operators worldwide.
ETERNITY NE's Mobile Interface supports full Quad-Band Operation (GSM850, 900, 1800, 1900MHz) for world-
wide use, for Global, Inter and Intra country roaming.
The Mobile Interface supports the following features:
• GSM 2G, GSM 3G network support.
• Selectable GSM Frequency Bands - 900, 1800, 1900, 850 + 1900, 900+1800 MHz.
• Programmable Network Selection - Manual and Automatic.
• Programmable Network Operator Codes in order of priority (from 1 to 9) in case of Manual Network
Selection.
• Programmable Speech Tx Gain
• Programmable Speech Rx Gain
• Selectable Incoming Call Modes - Allow, Ignore, Reject.
• SIM Card protection with a Personal Identification Number (PIN) and Personal Unlock Keyword (PUK).
• Wireless WAN support over 3G, which can be used to make VoIP calls (if VoIP module is installed).
