BVPU Configuration
Each BVPU PCB can support four VolP channels. One circuit on each unit can also be
assigned to handle facsimile traffic.
A circuit assigned for fax calls cannot handle voice as well, and visce versa, voice circuits are
not able to handle fax calls.
Note For the system to recognise the Duelitone Multi-frequency (DTMF) tones generated
by incoming calls, a BRCS (-4, -8, or -12) must be installed on the processor card.
BRCS is not required for BVPU dial pulse operation (see Program 30, LED 11).
BVPU controls, indicators, and interface connectors are shown in Figure 3-1 and described in
Table 3-1 .
BVPU Installation
Install the BVPU in accordance with the following steps:
1. Remove the BVPU PCB from its protective packaging.
2. Insert the BVPU into the appropriate slot, and apply firm, even pressure to ensure
proper mating of connectors.
3. Attach the 10BaseT Ethernet connection to the LAN Connector.
4. Connect a PC equipped with Maintenance Console Software (MCS) to the Serial Port as
shown in the diagram below. A serial connection is necessary to establish the IP address
of the BVPU. Once the IP address is allocated, programming and maintenance may be
conducted over the Ethernet port.
5. Once the BPVU is installed, gently pull it outward. If the connectors are properly
mated, a slight resistance is felt.
Note
Each BVPU interface board installed decreases the maximum system PSTN line
ports by four.
