–48V Cabinet Power Supply (VB-44033)
A –48V power supply must be installed in a cabinet when either DID, E&M and/or Ground Start
Trunks are employed in the cabinet.

Battery Backup (VB-44026)

The backup batteries supply power to the system in the event of a power failure. If the Battery Backup
option is chosen for the system, each cabinet requires its own set of batteries (1 kit per cabinet, 2
batteries per kit). The batteries can back up the system for up to 30 minutes.

Control Unit Processor Cards

Control Processor Card (68-port) - CPC-HS (VB-44440)

The CPC-HS card is a standard CPU unit for a system with up to 28 extensions and up to 68 ports.
The card uses a 16-bit CPU and does not support the DEC 16/24.
Included are a time switch (9 Highway x 9 Highway), a 4-circuit MFR (DTMF receiver circuit),
4-party conference circuits, service tone, a DTMF transmitter, an input terminal for external hold tone
and BGM source (RCA jack), EPA output (RCA jack), a connecting terminal for synchronization
package (VB-44460), and an interface connector for a compact flash card. The system control
program is downloaded to the internal memory of the system through the compact flash card.
Memory is retained with a backup battery.

Control Processor Card (72-port) - CPC-HS+ (VB-44440A)

The CPC-HS card is a standard CPU unit for a system with up to 28 extensions and up to 72 ports.
The CPC-HS+ card (VB-44440A) has all the features of the CPC-HS card, with the addition of extra
processing and Boot ROM (Read Only Memory) capacity that allows for expansion to CPC-HM
capacities.

CPC-HS to CPC-HM Capacity Expansion Kit (VB-444401/VB-444402)

These kits expand the CPC-HS/HS+ card to CPC-HM capacities.

Control Processor Card (120-port) - CPC-HM (VB-44441)

The CPC-HM card is a standard CPU unit for a system with up to
The card uses a 16-bit CPU and supports the DEC 16/24.
Included are a time switch (9 Highway x 9 Highway), a 4-circuit MFR (DTMF receiver circuit),
4-party conference circuits, service tone, a DTMF transmitter, an input terminal for external hold tone
(RCA Jack), an input terminal for BGM source (RCA jack), EPA output (RCA jack), a connecting
terminal for the synchronization package (VB-44460), and an interface connector for a compact flash
card. The system control program is downloaded to the internal memory of the system through the
compact flash card.
Memory is retained with a backup battery.

Control Processor Card (240-port) - CPC-HL (VB-44442)

The CPC-HL card is a standard CPU unit for a system with up to two cabinets, 128 extensions, and
240 ports. The card uses a 16-bit CPU and supports the DEC 16/24.
Included are a time switch (15 Highway x 15 Highway), a 4-circuit MFR (DTMF receiver circuit), eight
4-party conference circuits, service tone, a DTMF transmitter, an input terminal for external hold tone
(RCA Jack), an input terminal for BGM source (RCA jack), EPA output (RCA jack), a connecting
terminal for the synchronization package (VB-44460), and an interface connector for a compact flash
