1.1.2.4.2 Subtended Network Configuration with DS3+T1/E1 IMA NI-2 Cards
In a subtended network configuration using DS3+T1/E1 IMA NI-2 cards, you can subtend Cisco 6260
systems in a star topology. The eight E1 links can be used as network trunk or subtend interfaces or can
be combined into trunk or subtend IMA groups in the following two ways:

E1 IMA group or E1 User-Network Interface (UNI) as the network trunk with seven subtended node
chassis
If you are using an E1 trunk to the network, the trunk connection originates at one of the RJ-48
receptacle connectors on the E1 I/O module. Therefore, you can have only seven subtended
node chassis.
Up to seven individual E1 interfaces or up to four IMA groups, or a combination of the two
shows an example of a subtended network with a star topology. The subtending host chassis
