Table 7-186 describes the functions and features of a 4E1/T1-M card.
Function and Feature |
Description |
|---|---|
Data transmission |
Connects to a WAN through E1/CE1 interfaces to complete data transmission |
An E1 line supports up to 32 data channels and provides a total bandwidth of up to 2 Mbit/s. |
|
A channelized E1 line allows 31 timeslots to be flexibly bundled into multiple channels. The rate of each channel is 64 kbit/s multiplied by n, where n is the number of timeslots in the bundle and ranges from 1 to 31. |
|
Multi-service transmission |
Supports transmission of data, voice, and video services, without interference between these services. |
WAN aggregation |
Aggregates E1 lines of multiple branches to the headquarters. |
ISDN dialup |
Transmits various services, such as voice, high-speed fax, video call, intelligent telegraph, and teletext, at a rate of up to 2 Mbit/s. |
Flexible and easy deployment |
A CE1/PRI interface can be flexibly configured as a WAN interface or data interface, which simplifies networking. |
