Connection Boards

The standard connection board provides connection for 6 analogue telephones and 6 RCO outputs.

The ATLB provides connection for 6 analogue telephones and 6 RCO outputs. In addition the board provides protection against heavy transients and a ring voltage generator. This board is used when the subscriber cabling may be exposed to heavy transients and should always be used if there are outdoor cables. The ring voltage generator is needed when there are several phones in parallel on the same line, or the lines are very long.
