Chapter 2 Installation
After unpacking the unit, immediately inspect it for possible shipping
damage. If damage is discovered, file a claim immediately with the ship-
ping carrier; then contact the ADTRAN Repair and Return department.
ISDN NETWORK CONNECTION
The Express 4100/4110 supports either dial or leased operation. A single
RJ-49C modular jack labeled ISDN on the rear panel provides connection
to either network service.
Dial operation allows the user to dial out or receive calls over the public
network.
The leased operation mode supports dedicated 2B1Q data service at rates
up to 128 kbps by using a nailed up circuit, or a permanent connection
between endpoints.
See “Connector Pinouts” on page D-1 for ISDN network connector pin
assignments.
LOCAL AREA NETWORK CONNECTION
The Express 4100/4110 has a 10BaseT connector that provides half-
duplex 10 Mbps operation over a 4-wire twisted pair.
Other types of Ethernet interfaces (i.e., AUI, 10Base2, etc.) can be accom-
modated by obtaining an appropriate converter.
