8.10 Bandwidth Capabilities (Throughput)
All devices in the product family support approximately 416Mbps aggregate throughput. However, on the high-port
count devices with dual Ethernet Interfaces (the DS33X162 and DS33X82), it is necessary to conform to certain
constraints when interfacing with T3/E3 WAN lines. These constraints do not apply for T1/E1 transport. Also, these
constraints do not apply to devices other than the DS33X162 and DS33X82.
Table 8-5. Maximum Number of T3/E3 Lines Per Encapsulator (DS33X162 and DS33X82 Only)
Attempting operation of the DS33X162 or DS33X82 outside of these constraints may cause data loss. If the user
wishes to operate outside of the device’s designed capabilities, it is recommended that the user evaluate the
device performance under the specific application conditions and determine if the measured performance is
acceptable.
Note that the WAN Groups support the following rates:
Note that the individual WAN ports support the following rates:
