1.px0.demx004
Description
The analog E&M trunk card 1.px0.demx004 has four line circuits that satisfy
conditions for AT&T Type-V connections. Each port may individually be set to either
a two- or four-wire interface by appropriate configuration of the on-the-board
jumpers. The software supports many different line and register signaling types over
the E&M lines. An additional detector on the M-wire checks the DC feed on the line
for faulty conditions at far-end equipment. The analog E&M trunk card is available for
600 ohm resistive reference impedance. Each E&M port can be programmed as
incoming, outgoing, both-way trunk, or unavailable. Each E&M port can be
programmed for one of the following signaling types:
•
Pulsed line with decadic-address signaling
•
Continuous line with DTMF, MFC-R2, MF-R1 register signaling
•
Signaling types widely employed in CIS countries:
•
ANI (Automatic Number Identification) detection and query
•
Address signaling
•
Dial-Pulse
MFC-R1.5
Pulse-Packet-1
Pulse-Packet-2
Pulse-Packet-3a
Pulse-Packet-3b
•
