The practical bits

The form factor of a Magic Box is the same as a standard drive so it's easy to incorporate into existing hardware, or with the 19" rack mounting kit available separately.  Three Magic Box units fit into 1U of rack space.

Calls are highly compressed using a 24000bps stereo codec, and securely encrypted using the industry standard 256-bit key AES algorithm.

Expansion is easy since each unit is self contained.  It's therefore the perfect solution at sites where completely separate recorders are required for security reasons.

USB connections are mounted both front and rear to facilitate ease of connection when installed into a PC chassis.  More importantly the forward facing telephony connectors ensure changes are effected with no disruption to other wiring in the vicinity of TIM Talk.

Connection

The hardware device is connected to the host server by way of a high-speed USB2.0 cable from the rear of the unit.

Limitations

By default, the system is supplied with Microsoft SQL Server 2005 Express, therefore the call database has an upper limit of approximately 5.5 million call recordings.  The server should not use any other USB devices, since these may interfere with the smooth running of the call recording bus.

Inputs

Standard analogue line (POTS), basic rate (BRI) and primary rate (PRI) ISDN inputs are available.  For ease of access, all input connections are made via front panel RJ45 sockets.

Power requirements

Each TIM Talk interface can be powered via an internal power supply of a PC. A standard PC power socket is available at the rear of the unit.  A separate external power supply is available.

Storage Requirements

Capacity is limited by the amount of hard disk storage available. The following is a rough guide to the amount of storage you may need:

• 250GB Hard disk space: 44,000 channel hours recording
• 500GB Hard disk space: 88,000 channel hours recording
• 750GB Hard disk space: 132,000 channel hours recording

Minimum PC specification

• Microsoft Windows XP Professional, or Server 2003
• Dedicated USB hub and controller
• 2GB RAM
• Pentium 4 Core2 Duo 3.2GHz CPU, or equivalent
• Serial COM port
• PS2 keyboard, and mouse
• PC must be a dedicated machine

The magic box

Occupying a 5 1/4" drive bay (146mm wide, 227mm deep, 42mm high; about the size of a standard CD-ROM drive) on your PC, one box will monitor up to 30 digital ISDN lines into your company.

Up to four boxes can be mounted inside a standard mini tower PC allowing up to 120 ISDN circuit capacity.

For higher capacities, the boxes can be bolted horizontally and mounted in a standard server rack or networked PCs can be interconnected for very large scale call recording.
