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
ß
ashing and the remaining LEDs will be off.
