Operation as terminal/add-drop station in the basic network with QD2
interface
If the XMP1 Flexible Multiplexer is operated as terminal or add-drop station
in a basic network monitored and manged by the ServiceOn Access, the
Central Unit GN/QD2 (AN00239607) is required.
8.2.2 Redundancy modules
Each Central Unit can be doubled. The redundant Central Unit is identical
with the active Central Unit and must be mounted in the card slot next to it
(card slot 7 / 15 or 31).
Note: In the Operator Software, the appropriate Central Unit to
be mounted as redundant Central Unit, e.g. "ZT2 QD2ZT
doubled", must be selected using the ’Standby Modules’ dialog.
8.2.3 Ethernet adapter
From XMP1 version 4.x onwards the Central Units CC and GN can
optionally be equipped with the Ethernet adapter module (AN00114784;
62.7040.303.00-A001). This module provides an Ethernet interface for
connecting the Central Unit to a LAN. Thus, access to the XMP1 network
becomes possible with ServiceOn XMP1 (SOX) via IP. The IP configuration
can take place manually (LSP/WINLSP) or via a BootP/DHCP server.
8.2.4 CU-E sub-module
When using the SDH expansion, the Ethernet interface is provided by the
CU-E sub-module (05HBA00006AAX). This sub-module is mounted on the
Central Unit.
8.2.5 Bus terminations
Bus terminations are not required for XMP1 subracks (16) and (8). These
are integrated in the backplane.
For XMP1 subrack (16/32), two bus terminations must be provided.
8.2.6 Port modules
The following port modules are available:
