Differences between the XE1276A and XE1276

In creating the XE1276A Xecom strived to make the new

product compatible with both the XE1276 and XE2476.

Unfortunately some features could not be supported in

the new product. We believe the improvements made

will benefit most XE1276 customers.

New Features: The XE1276A features reduced power

consumption and the addition of non-volatile memory for

modem configuration storage.

We reduced XE1276A power consumption in two ways.

First, we reduced operating power by 20% using new

low power components. Second, we added a sleep

mode. The XE1276A automatically enters sleep mode if

there is no activity for 5 seconds. In sleep mode power

consumption is reduced to less than 50 milliWatts.

The addition of non-volatile memory permits the user to

configure the modem once and never configure it again.

It also permits storage of up to four telephone numbers

which can be recalled for dialing.

Unsupported XE1276 Features: The features lost in

the XE1276A redesign were the specialized interface

pins for Auto-answer, Command Mode, and Speed

Indication. The XE1276A does not support High-Speed

Indication on Pin 1, Command Mode Indication on Pin 2,

or Auto Answer Disabled on pin 3. Please contact

Xecom's Application Engineering Department to assist in

working around these lost features.
