Table 6-1 Common Ethernet Cable Categories
Category Spectral B/W Length LAN
Cat3 16 MHz 100 m 10Base-T
Cat4 20 MHz 100 m 16 Mbps
Cat5e 100 MHz 100 m 100Base-T
Cat6 250 MHz 100 m Emerging
Cat5e cabling meets the requirements for the Dolby Lake Processor Ethernet network,
and Cat6 cabling exceeds the requirements. Use either cable.
Note:
Existing infrastructure cabling in installations may be Cat3 or Cat4. Neither of
those satisfies the bandwidth requirements of 100Base-T networking.
6.3 Connecting Multiple Processors on Wired
Ethernet Networks
Due to the auto-sense and auto-uplink features of the Ethernet ports, connecting
multiple units is a simple task. A free-topology network can be implemented,
including external switches or hubs.
The simplest network is to connect multiple Dolby Lake Processors together, and
then connect a PC to any available port on one of the processors on the network, as
shown in Figure 6-1.
Figure 6-1 Simple Network Connection
More complex networks are possible, which may be required due to physical
placement of the processors. Standard Ethernet repeaters and switches may be a part
of the network, as illustrated in Figure 6-2.
