2E1/T1-F (2-Port Fractional Channelized E1/T1 WAN Interface Card)

Card Overview

The 2E1/T1-F is a data and image signal processing module for a router and provides two E1/T1-F interfaces for WAN connection.

A 2E1/T1-F card can be installed in a SIC slot of a router.

Figure 7-87 shows the appearance of a 2E1/T1-F card.

Functions and Features

Table 7-205 describes the functions and features of a 2E1/T1-F card.

Table 7-205 Functions and features

Function and Feature	Description
Data transmission	Connects to a WAN through E1-F interfaces to complete data transmission.
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	In unframed mode, an E1 line provides 2 Mbit/s bandwidth for service traffic transmission without timeslot division. In framed mode, an E1 line is divided into 32 timeslots. Multiple timeslots can be bundled into a low-speed E1 channel for service traffic transmission.
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.

Table 7-206 Indicator description

Number	Indicator	Color	Description
1	STAT	Green	Slow blinking: The system is running properly. Fast blinking: The system is being powered on or restarting.
		Red	Steady on: A fault that affects services has occurred and cannot be rectified automatically. The fault needs to be rectified manually.
		Off	The system software is not running or is resetting.
2	LINK/ACT	Green	Steady on: A link has been established on the interface. Off: No link is established on the interface.
		Amber	Blinking: Data is being transmitted or received on the interface. Off: No data is being transmitted or received on the interface.
		Off	The interface is not connected.
