Provisioning a Subrate E3 or T3 Interface
Subrating a T3 or E3 interface reduces the peak access rate by limiting the data transfer rate. Subrate
modes configure the line card to connect with Cisco port adapters and with customer premise Data
Service Units (DSUs). Bandwidth provisioning tables are provided in this guide to help you connect the
Cisco 10000 series router T3 or E3 interface with several manufacturer's DSUs.
You can provision a subrate E3 or T3 interface on the following Cisco 10000 series router line cards:

Implementing a Subrate T3 or E3 Interface
DSU manufacturers supporting a subrate T3 or E3 interface use proprietary methods of multiplexing.
The Cisco IOS software command line interface (CLI) supports the dsu mode and dsu bandwidth
commands, which configure the line card to emulate a DSU manufacturer's proprietary multiplexing
scheme.
The default DSU mode is cisco. If the remote end is not a Cisco DS3 subrate interface, use the dsu mode
command to specify the DSU.
For T3 interfaces, the Cisco 10000 series router supports the following DSUs:
