30 Product Description
The enhanced CPU (P/N 0891038) provides:
● 200 trunk ports maximum
● 512 extension ports maximum
- Aspire M/L: 256 analog/digital extensions,
- Aspire XL: 384 analog/digital extensions
- Aspire M/L or XL: NEC Wireless 2.4 GHz and IP Phones can have a maximum of 512 ports,
however, more than 256 (Aspire M/L) or 128 (Aspire XL) Wireless and IP phones reduces
the number of available extension ports.
● 256 virtual extensions
● Supports the 4VOIPU PCB and 4VOIPDB
● Supports TAPI 1.x
● VRS (Requires DSPDB Daughter Board)
The enhanced CPU supports:
Each version of the NTCPU provides the following:
● Five diagnostic LEDs which indicate the status of various system functions
During normal operation, the “RUN” LED will be ßashing and the remaining LEDs will be off.
● 1019x1019 Time Division Multiplex Switch (TDM Switch)
● Digital Phase Locked Loop (DPLL)
● Tone Generator
● DTMF Tone Sender
● 32 Tone Resources (for DTMF Receiver, Caller ID Receiver, and Call Progress Tone Detection)
● System Tone Sender
● MFC Tone Sender
● MF Signal Sender (Sends caller information to CO for E911)
● Call Progress Tone Detector
● C-Channel Control
● Conference; 64 Channels
● Caller ID Receiver; 32 Channels
