The CL 740 Teleco system has been designed to solve the problem of the adaptation of the signalling standard among the interface devices (self-commutator or user device) and the telephone transmissive channels, in the far subscriber seat.

The system can be used every time that a telephone multiplex device is installed between the exchange and the user telephone.

Through an only converter it is possible to realize, through the jumper predispositions, different configurations of line prolongation and more precisely:
– PLA/T.
– PLA/C.
– BC.
– BL.

From the constructive point of view it has been realized a solution that allows to reduce at minimum the occupied space.

The CL 740 TELECO system is constituted by:
– Module with 2 signalling converters (mod. PL 745 Teleco).
– Sub-device for Teletaxe (mod. TX 745.1 Teleco).
– Signals generator module (mod. GS 748 Teleco).
– Sub-rack for 10 signalling converters module (mod. ST 578 Teleco).
– Distribution frame rack (mod. ST 544 Teleco).
– Rack N2C for 6 sub-rack ST 578 (mod. ST 508 Teleco).
– Rack N2C for 5 sub-rack ST 578 (mod. TN 508 / R Teleco).
