Introduction
OVERVIEW
The Nx56/64 (EIA-530) option module is one of the op-
tion modules available for use with the ADTRAN TSU
100, 120, 600, and 610. The Nx56/64 (EIA-530) option
module installs in the option slot of the TSU 100 and pro-
vides an additional synchronous EIA-530 interface port.
When used in the TSU, this interface port allows an addi-
tional DTE to have access to the T1 service.
Functional Description
The Nx56/64 (EIA-530) interface operates in the option
slot of the TSUs, or as a plug-on to any option module and
is under the control of the TSU. The Nx56/64 (EIA-530)
option module is configured from the front panel or by an
external PC program. The internal menus for its configu-
ration are part of the Nx card and are automatically in-
stalled when the option module is plugged into the TSU.
