Product Data
5.5.3 Transmission Network Connection
LAPD concentration and LAPD multiplexing can be used to make the
transmission resource more efficient.
The DXU is equipped with four transmission ports. It is connected to a
2 Mbit/s PCM signal or to a 1.5 Mbit/s signal. Two types of
transmission network standards may occur: 2 Mbit/s PCM with
75
unbalanced lines or 120
balanced lines. The second case is
1.5 Mbit/s PCM balanced 100
lines.
On the top part of the cabinet are connections for optional transmission
equipment which is mounted externally. The connections are:
•
PCM cables
•
+24 V DC
•
Blank panels for connectors to Optional Transmission Equipment
(OXU)
5.5.4 Transmission Power
RBS 2206 can feed the transmission equipment with +24 V DC. The
maximum power output is 250 W.
BBS 2000 can feed the transmission equipment with +24 V DC. If a
DC/DC converter is used, the BBS 2000 can deliver -48 V DC. The
converter is mounted in the BBS 2000.
Maximum power outputs from the BBS 2000 are given in the table
below.
