8E1/T1-F (8-Port Fractional Channelized E1 WAN Interface Card)
Card Overview
The 8E1/T1-F is a data and image signal processing module for a router and provides eight E1/T1-F interfaces for high-density WAN connection.
This card does not support the T1-F interface mode.
An 8E1/T1-F card can be installed in a WSIC slot of a router.
Figure 7-93 shows the appearance of an 8E1/T1-F card.

Functions and Features
Table 7-218 describes the functions and features of an 8E1/T1-F card.
Function and Feature |
Description |
|---|---|
Data transmission |
Connects to a WAN through E1-F interfaces to complete data transmission. |
A fractional channelized E1 line allows 31 timeslots to be flexibly bundled, but only one bundled channel is supported. The interface rate is 64 kbit/s multiplied by n, where n is the number of timeslots in the bundle and ranges from 1 to 31. |
|
Service communication |
|
Cost-effective access service |
Compared with a channelized E1/T1 interface card, a fractional channelized E1/T1 interface card provides the access service at lower cost. |
Pseudo wire emulation edge-to-edge (PWE3) |
Allows users to smoothly connect to an IP network from their networks, without changing the original access methods. |
Connects networks that use different access methods to an IP network. |
