XMP1 Release 5.5 System Description
SOX Single-User application
Page 1-16 Proprietary Information Aastra
A special variant of the single-user application is the division of a network
into several sub-networks (Areas) while maintaining the single-user
concept.
Access to an area is possible via V.24 and/or Ethernet interfaces. Access
via the Ethernet is recommended. For this purpose, an Ethernet interface
must be provided on the Central Unit (> V3.0) of the corresponding access
nodes. This Ethernet interface is made available by the Ethernet adapter or
- with SDH modules - by the CU-E sub-module.
The overall XMP1 network shown in the diagram below is logically split up
into individual sub-networks (Areas) by appropriate segmentation. The
individual sub-networks 1, 2 and 3 are still forming the overall network,
however, with three separate management accesses. The traffic data are
still transmitted between the sub-networks, the managment information
contained in time slot 0 being blocked at the area transition of the E1
interface.
