摘要

The dimensioning of an Alcatel S12 exchange is done according to the description in chapter 2. The dimensioning is done in a very flexible way. A traffic increase, whether it comes from (new) ASMs or DTMs can easily be handled by increasing the number of SACEs, SCMs and other equipment. The IRSUs in an MD can be configured in many ways as described in chapter 3. For example can one large IRSU or up to 8 smaller IRSUs be connected to an IRIM pair. In addition, the number of links (2 Mbit/s) connected to the IRIM-pair can vary, but the recommended number of links are two or four. In addition, a mini IRSU may be connected, but care must be taken because of special traffic limitations. The D channel used by digital subscribers connected to an MD is normally connected to allocated PS channels on the MD links. One PS channel per link may be assigned. If the PS traffic is low, there will be a possibility to use the signalling channel both for signalling and packet traffic which means that the circuit traffic capacity is increased.
