STBG4 module

This current-limiter module is designed for use with the analogue trunk interface in France.
It incorporates the current-limiter components and overvoltage isolators required.
The module does not occupy any options-bus lines.
The circuitry of slot X3 is designed such that the module cannot be inserted with reversed po-
larity.
The STBG channel is looped between the TLA and the trunk.
