Chapter 3. 9500 MXC Nodes
Vol. II-3-36 Alcatel-Lucent
• M13 multiplexer, where one or maximum two DS3 tributaries (Tx/Rx 1 and Tx/
Rx 2) are multiplexed to a DS1 backplane bus, each as 28xDS1, in accordance
with T1.102 and T1.107. Operation is compatible with industry standard M13
multiplexers, meaning that at the DS3 destination a 3rd party M13 multiplexer
can be used. Allows side-by-side transport with other DS1 traffic over a 9500
MXC link
• E3 transparent, unchannelised transport for ATM and video (e.g. MPEG2
video) E3 streams. Each of the two transparent E3 interfaces (Tx/Rx 1 and
Tx/Rx 2) provides a 34.368 Mbps connection for transport as 17xE1 over a
9500 MXC NxE1 network. Allows side-by-side transport with other E1 traffic
over a 9500 MXC link.
The three E3/DS3 trib ports are presented as paired 75 ohm, unbalanced, mini
BNC female connectors.
Trib cables are available, as accessories, to provide:
• Mini BNC male to mini BNC male; two required per trib.
• Mini BNC male to standard BNC male; two required per trib.
DAC 3xE3/DS3M plugs into any of the INU/INUe universal slots. (Within an
INUe but where access to NMS overhead is required for a ring-closure
application, it must be fitted in slots 1 to 6).
Where protection of the DAC is required (line protection), two DAC 3xE3/
DS3M plug-ins can be installed and splitter Y-cables fitted to provide extensions
to BNC male connectors.
Figure 3-20 shows the DAC 3xE3/DS3M front panel layout. Table 3-18
describes the interfaces.
