1E1/T1-M is a data and voice processing module for a router and provides one CE1/CT1/PRI/VE1 interface for WAN connection, digital and analog voice transmission, and
ISDN dialup. A 1E1/T1-M card can be installed in a SIC slot of a router.
Data transmission:Connects to a WAN through E1/CE1 interface 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.
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/CT1/PRI/VE1 interface can be flexibly configured as a WAN interface, data interface, or voice interface, which simplifies networking.
Voice gateway:Works as a gateway to provide access to a PSTN or TDM PBX network, and supports a maximum of 30 call connections.
