Interface converter,

modem eliminator, and elastic

buffer—all in one compact

unit!

Supports V.24/RS-232,

V.35, V.36/RS-449, X.21, and

G.703 interfaces.

Field-replaceable interface

modules.

DCE/DTE switch for

each module (except for G.703

interface).

Speeds up to 2.048 Mbps.

G.703 support for

64-Kbps co-directional, T1,

and E1.

he Modular Modem

Eliminator connects any

two data-communications

products with similar or

different interfaces. It

functions in three ways: as an

interface converter, as a

modem eliminator, and as an

elastic buffer. A handy switch

lets you select the mode of

operation.

• As an interface converter,

the unit lets you connect

DTE to DCE with different

interfaces. It converts the

physical and electrical

difference between the two

interfaces.

• As a modem eliminator, the

unit eliminates the need for

two synchronous modems.

It allows you to connect two

DTEs with similar or

Use the ME260A/ME260AE as an interface converter, modem

eliminator, or elastic buffer.

Three units in one:

interface converter,

modem eliminator, and

elastic buffer.

Typical Application

different interfaces. The

converter provides clock,

and performs handshaking

of control signals,

simulating modem

operation.

• As an elastic buffer, the unit

lets you connect two

independently-clocked

DCEs. It buffers data in both

directions to overcome

different clock phases and

reduce data loss for different

clock sources. The two DCEs

may have similar or

different interfaces.

Key Features

And the Modular Modem

Eliminator runs at data rates

up to 2.048 Mbps using

internal or external clock.

A complete system consists

of the Modular Modem

Eliminator and two Interface

Modules of your choice.

• General-purpose interface

modules are available for

RS-232, V.35, X.21, and V.36

interfaces.

• CCITT Rec. G.703 interface

modules are available for

64-Kbps DB15, 2.048 Mbps

Coax, and 1.544-Mbps T1.
