4-Port Digital Call Logging Unit

11.5.1

Description

The 4-Port Digital Call Logging Unit is a Universal Serial Bus (USB)
device designed to be installed in the "BackOffice" next to the
telephone system. These devices can be stacked on one PC (up to
12 per PC or 48 ports) or, if larger installations are required, multiple
PCs can be used with calls being stored on one central drive.
Connectivity is accomplished via parallel wiring tapped across the
same pair that feeds the D
software allows naming and mapping of each port independently.
The device does not interfere with communications between the PBX
and the digital telephone. It does not require USB power or a
connection to the PC to maintain the functionality of the telephone in
its normal manner.
The device meets the appropriate FCC and UL requirements required
for this type of communications device.
The device is soft up-loadable: the firmware and FPGA low-level
protocol decryption is uploaded from the PC driver and the 4-Port
Digital Call Logging Unit application at runtime. This allows easy
upgrade and enhancement of the product in the field as required.
