Typical uses:
- Local repeater to drive long cables.
- Interface to 75 ohm or 120 ohm test equipment.
- Distribution Amplifier for Broadcasters etc.
- Amplifier to feed remote protocol analyser via multiplexers.
- Non intrusive tap for monitoring call data

Specification:

Input:
Inputs can be used with 0dB to -30db protected monitor points. (This represents an effective series resistance of 2400 ohms - This value may vary from 470 ohms to 4700 ohms with no signal degradation.) Maximum recommended cable length 1m - 3m depending on local conditions. Please note that we have occasional enquiries for 64 Kb versions; usually this refers to the demultiplexed data channels data rate. The actual data rate of the multiplexed stream is actually 2048 Kb.

Outputs:
Outputs conform to CCITT G703 specification.
2048Kb 75ohm / 120 ohm (E1).
1544 Kb 100 ohm (T1).
Cable Length - 1000 ft typical
