1.1.2.4.3 Subtended Network Configuration with OC-3c/OC-3c NI-2 Cards
In a subtended network configuration using OC-3c/OC-3c NI-2 cards (SMF or MMF), you can subtend
up to 12 OC-3c configured chassis in a daisy chain, all connecting through one subtending host chassis
to the ATM backbone (see
Figure 1-5
).
Note
The Cisco 6260 chassis can also serve as the subtending host chassis to, or as a subtended node chassis
from, the Cisco 6100, Cisco 6130, Cisco 6015, or Cisco 6160 chassis.
