ALCATEL REFLEXES 3G TERMINALS TERMINALS
Ed. 046/8 Réf. 3EH 21000 BSAA
4094 ISW module
This module connects an S0 terminal to the system via a UA link.
This optional module provides an S0 power bus which requires an external power supply (230V AC/
42V DC adapter), allowing terminals without their own power supply (ISDN terminals, etc.) to be con-
nected to the bus.
The mains supply transformer serves as a sectioning mechanism for the S0 interface. It must therefore
remain easily accessible.
The S0 bus can be a point to point or short passive bus covering 150 m (up to 5 terminals, of which a
maximum of 2 may be powered remotely). Operation is not guaranteed in the event of a power outa-
ge.
