Primary to Basic Rate ISDN Multiplexer
TECHNICAL: 0118 931 2233
Product Specifications
ISDN Connections
The Primary to Basic Rate ISDN Multiplexer connects to the network via an ISDN S2m or
T.1 PRI interface acting as a terminal.
The Primary to Basic Rate ISDN Multiplexer provides up to sixteen BRI's via line cards with
8 S0 or 8 U ports and one ISDN S2m or T.1 PRI port operating in NT mode. The BRI
interfaces can optionally provide power feeding (40V, 1W for S0 ; 88V, 3W for U).
LED's indicate the operating level of each port. (1) P led to indicate physical layer and data
link layer activated, (2) B led to indicate that at least one B channel is active.
Analogue (PSTN) Connections
The Primary to Basic Rate ISDN Multiplexer provides up to 32 analogue lines via line cards
with 16 analogue lines.
The analogue lines feature -48V feed and ringing. Tone (DTMF) and pulse dialling are
supported. FSK (ETSI), and FSK (Bellcore) caller ID signalling are provided.
An LED at each port indicates off-hook and ringing.
Terminal Port
A V.24 port is provided allowing the connection of an ANSI (or Wyse 50) compatible
terminal or PC for setting up the unit.
Ethernet Port
An IEEE 802.3 Ethernet port is provided for connection to a local area network.
LED's indicate (1) network present, (2) network activity.
Modem Port
An optional modem port is provided to allow the Primary to Basic Rate ISDN Multiplexer to
be controlled remotely.
LED's indicate that the modem is (1) off hook / ringing, (2) connected.
