Battery Backup (VB-44026UK)
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 (78-port) - CPC-HS (VB-44440UK)
The CPC-S card is a standard CPU unit for a system with up to 32 extensions and up to 78 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), eight 3-
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 (132-port) - CPC-HM (VB-44441UK)
The CPC-M card is a standard CPU unit for a system with up to 64 extensions and up to 132 ports.
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), eight 3-
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 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.

Network Synchronizing Unit - SYNC (VB-44460UK)
This unit provides network synchronization and is required with digital circuits such as ISDN. The
SYNC card synchronizes the PCM clock with an outside resource. When digital circuits are used, one
SYNC card is required and installs on the CPC-HS or CPC-HM card.
