ping damage. If damage is discovered, file a claim immediately with
the shipping carrier; then contact the ADTRAN Repair and Return

IDSL NETWORK CONNECTION
The Express L128FP supports leased operation. A single RJ-49C
modular jack labeled ISDN on the rear panel provides connection to
the network. Leased operation mode supports dedicated 2B1Q data
service at rates up to 144 kbps by using a nailed up circuit, or a per-
manent connection between endpoints.
ISDN network connector pin assignments are given in Appendix D.
L128FP LOCAL AREA NETWORK CONNECTION
The Express L128FP has a single 10BaseT connection port that pro-
vides half duplex 10 Mbps operation over a 4-wire twisted pair. Other
types of Ethernet interfaces (i.e., AUI, 10Base2, etc.) can be accommo-
dated by obtaining an appropriate converter.
