Contact your DeTeWe distributor or
local retailer if you want to purchase
one of these cards.
In cascaded configurations, mas-
■
ter and slave systems are con-
nected via the PCM port (RJ45
socket).
In cascaded OpenCom 510 con-
■
figurations, the slave system re-
quires an MC+1-3 central con-
trol module of its own.
In cascaded OpenCom 510 con-
■
figurations, a CompactFlash card
must be installed in the master
system; it is not necessary to in-
stall one of these cards in the
slave system.
In cascaded configurations, the
■
central control modules use the
PCMV interface to exchange sys-
tem signals. The PCMV interface
provides the system clock sig-
nals, access to the 16-Mbit/s
PCM highway, and a 2-Mbit/s
LAN.
In cascaded configurations, the
■
S1 and S2 DIP switches are used
LED 1: Flashing yellow
LED 2: Constantly green
58
MC+1-3
Flashing green/yellow
for frame coding (PBX Cascading
starting on page 98).
The Ethernet port (10/100
■
Mbits/s) can be used to connect
the OpenCom 510 to the LAN.
The V.24-1 interface can be used
■
to connect additional apparatus,
e.g. a computer for analysing
call charges.
For information on the V.24 in-
terface pin assignment, refer to
COM Port starting on page 44.
