IP Hardware
PCBs:
● NTCPU - Signals the gateway with VoIP communication
● 4VOIPU - VoIP PCB provides a 4-channel voice packet gateway unit and works as a media
gateway for VoIP communication. This PCB is required for either VoIP trunks or when using
VoIP keysets which talk to non-IP keysets. VoIP keyset-to-VoIP keyset can talk without a
media gateway and without using any DSP resources using the Peer-to-Peer feature
(page 694). The 4VOIPU PCB requires 4 trunk ports.
● 4VOIPDB - VoIP daughter board provides an additional 4 channels when attached to either
the 4VOIPU or 16VOIPU PCB. The 4VOIPDB requires 4 trunk ports.
● 16VOIPU - VoIP PCB provides a 16-channel voice packet gateway unit and works as a media
gateway for VoIP communication. This PCB is required for either VoIP trunks or when using
VoIP keysets which talk to non-IP keysets. VoIP keyset-to-VoIP keyset can talk without a
media gateway and without using any DSP resources using the Peer-to-Peer feature
(page 694). The 16VOIPU PCB requires 16 trunk ports.
● 16VOIPDB - VoIP daughter board provides an additional 16 channels when attached to the
16VOIPU PCB. The 16VOIPDB requires 16 trunk ports.
● 8SHUBU - Provides an 8-port switching hub for use with the Aspire system. This PCB can
also be used to provide PoE for Aspire IP equipment.
When installing a VoIP PCB, the system allocates the maximum number of trunk ports for the PCB
being installed. For instance, the 4VOIPU PCB requires 4 ports, while the 16VOIPU PCB requires
16 ports. If the PCB is not going to be used for trunks, the logical trunk ports can be set to ‘0’ in
Program 10-03-01 : PCB Setup, but the physical trunk ports are still assigned to the PCB and can-
not be used for any other PCB. If the trunk ports will not be used and the trunk port usage is a con-
cern, plug the VOIPU PCBs into the system last. The system will allow extension ports to be
assigned even if there are no trunk ports available. A maximum of 512 IP extensions or 200 IP
trunks are possible with the Aspire. The VoIP PCBs can be plugged into any universal slot.
Terminals:
● IPhone - Aspire 34-button multi-line IP phone
● IP Adapter - IP adapter connects an Aspire keyset to the VoIP network
The phone with the adapter installed is also referred to as the Dterm IP phone.
● ITR-2D-1 - H.323 IP phone
H.323 phones do not support the ability to send digits after a call has been placed and
before it is answered. This means that features which use single digit service codes, such
as Voice Over and Barge-In, are not available with this type of phone. These phones do not
provide P-codes, and therefore, cannot be used with the inDepth application.
Power must be supplied to the IPhone or the Aspire keyset with IP adapter using either a local or
central power supply. The ITR-2D1 phone requires local power. If there is a power outage, the VoIP
phones will not work unless the phones are plugged into a UPS (uninterruptible power supply).
When the first IP phone is plugged in, the system automatically assigns the next three consecutive
station ports available as IP ports. The next three IP phones installed will use this group of ports.
When the fifth IP phone is connected, the next 3 consecutive station ports available will be assigned
as IP ports.
