Card Overview
LR4 PSTN card with four trunks (analogue signalling)
This card provides a remote set disconnection detection function. The LR4 card
must sometimes be fitted with DTOC cards, depending on the specific
configuration.
Card Overview
LT2 This card is used as a PCM digital junction or to provide ISDN PRI access. The
PCM digital interface can have 32 channels (time slots) operating at 2
Mbps.
LI1 This card has two tie line circuits and can be wired for two-wire or four-wire
operation.
Card Overview
CA1 This card has four RS232C ports enabling the connection of four asynchronous
data transmission terminals (DTEs) in V28 and/or V10 mode. The four circuits
provide a data communication terminal equipment (DCE) function.
This card can be fitted with up to four DTEs in V10 mode.
CP1 This card has two circuit packet-switching lines; it is used for the X.25 protocol
(data packet transmission).
CS1 This card has two RS232C ports enabling the connection of two synchronous data
transmission terminals (DTEs) in V28 and/or V10 mode.
This card can be fitted with up to two DTEs in V10 mode.
FTXA 12 kHz charge detection card.
This card is used to detect call charging pulses.
This card is mounted on an LR4 card for each trunk.
FTXC 50 Hz charge detection card.
This card is used to detect call charging pulses.
This card is mounted on an LR4 card for each trunk.
