VII.3.G. EX200 (0/8KoU) DIGITAL EXTENSION
MODULE
In addition to the common circuits mentioned above, there are 8 identical special digital
extension circuits on the EX200B (0/8KoU) card.
Since the card has a digital protocol due to its structure, no extra circuit is needed; however,
each extension has an individual digital driver.
Connections to the EX200B (0/8KoU) card are made over the CON3 line connection card
VII.3.H. EX200 (0/16KoU) DIGITAL EXTENSION
MODULE
In addition to the common circuits mentioned above, there are 16 identical special digital
extension interface circuits on the EX200B (0/16KoU) card.
Since the card has a digital protocol due to its structure, no extra circuit is needed; however,
each extension has an individual digital driver.
Connections to the EX200B (0/16KoU) card are made over the CON2 line connection card.
VII.3.I. EX200 (8 T0/0) ISDN BRI LINE MODULE
In addition to the common circuits explained above, there are 8 identical ISDN BRI line
circuits on the EX200B (8T0/0) card.
Since ISDN is a digital protocol, no extra circuit is needed; but each line has a standard ISDN
BRI driver.
Connections to the EX200B (8T0/0) card are made over the CON2 line connection card.
VII.3.J. EX200 (0/8LB) LOCAL BATTERY EXTENSION
MODULE
In addition to the common circuits specified above, there are 8 identical LB line circuits on
the EX200 (0/8LB) card.
The EX200 (0/8LB) module has been designed in order to provide the interface required for
the connection of field telephones to an exchange of the DS200 series. Thanks to that
interface, eight local battery telephones can be connected to the exchange. All of the eight
telephones can be forwarded to a single telephone on the exchange side, as well as each
local battery telephone can individually be forwarded to a specific telephone directly, which
has been assigned to it.
Connection to field telephones shall be two-wire. Since that type of telephones are not fed
with DC voltage and since the EX200 (0/8LB) module provides the user with the possibility of
changing incoming-outgoing voice gain, cables extending to long distances can be installed.
