Chapter 2

Installation

After unpacking the unit, immediately inspect it for possible shipping dam-

age. If damage is discovered, file a claim immediately with the shipping car-

rier; then contact the ADTRAN Repair and Return department.

ISDN NETWORK CONNECTION

The Express XL/XLT supports either dial or leased operation. A single RJ-45

modular jack labeled ISDN BRI U on the rear panel provides connection to ei-

ther network service.

Dial operation allows the user to dial out or receive calls over the public net-

work.

The leased operation mode supports dedicated 2B1Q data service at rates up

to 144 kbps by using a nailed up circuit, or a permanent connection between

end points.

See Appendix D on page 143 for ISDN network connector pin assignments.

LOCAL AREA NETWORK CONNECTION

The Express XL/XLT has a 10BaseT connector that provides half-duplex 10

Mbps operation over a four-wire twisted pair. Place the switch in the TO HUB

position when connecting to a 10BaseT concentrator or Hub. Place the switch

in the TO NIC position when connecting directly to a computer’s 10BaseT net-

work interface card.

Other types of ethernet interfaces (i.e., AUI, 10Base2, etc.) can be accommodat-

ed by obtaining an appropriate converter.
