1.1.2.4 Subtended Network Configuration

The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a
subtended network.

Services and aggregates the data from one or more Cisco 6260 chassis into a subtending host chassis
to take advantage of the data network interface on the subtending host chassis.
Reduces the number of ATM edge-switch ports required to terminate the chassis.
Supports a Cisco 6260 system with a POTS splitter and a Cisco 6260 system without a POTS
splitter configuration.
Four arbitration priorities, one for each quality of service (QoS) level. The supported QoS service
levels are
Constant bit rate (CBR) for rate-limited services that require guaranteed bandwidth and
–
bounded delay
Variable bit rate real time (VBR-rt) for delay-sensitive voice and video services
–
Variable bit rate nonreal time (VBR-nrt) for high-priority data services
–
Unspecified bit rate (UBR) for low-priority data services
–
Explicit forward congestion indication (EFCI) marking for available bit rate (ABR) service support.
Guaranteed frame rate (GFR).
