Figure 7-2. Multiline Circuit Types
A multiline circuit reacts to individual data paths coming up and going down by
adding to and subtracting from its pool of active data paths, and can operate with
some of its data paths down.
Grouping Data Paths
The data paths that form a multiline circuit must share the same bandwidth,
Maximum Transmission Unit (MTU), and encapsulation method. T1, E1, MCT1,
MCE1, HSSI, and Bay Networks Standard synchronous lines share the same
encapsulation method, so you can group any of these lines to form a multiline
circuit as long as they share the same bandwidth and MTU.
Frame Relay and PPP each have unique encapsulation methods. You cannot mix
these line types with any other line type when you create a multiline circuit.
