Remote Access Server
Figure 8 shows a remote access server configuration.
Figure 8. Remote Access Server Configuration
In this application, eight TDM ports are connected to external framers. In the MPC8560, each group of four
ports supports up to 128 channels. One TDM interface can support 32–128 channels. The MPC8560
receives and transmits data in transparent or HDLC mode and stores or retrieves the channelized data from
memory. The data can be stored either in the DDR SDRAM memory or in memory residing on the local bus.
The main trunk can be configured as one of the following:
155-Mbps full-duplex ATM, using the UTOPIA interface
10/100/1000BaseT Ethernet with MII/GMII/RGMII interface
High-speed serial channel (up to 45 Mbps)
In ATM mode, there may be a need to store connection tables in external memory on the local bus (if more
than 128 active connections are needed). The need for local bus memory depends on the total throughput of
the system. The MPC8560 supports automatic (no software intervention) cross connect between ATM and
MCC, routing ATM AAL1 frames to MCC slots.
