DIDCSU 2912 Overview
This manual describes the DIDCSU 2912, a Dual Integrated Data
Service Unit/Channel Service Unit with two E1 network ports or two
T1 network ports, as well as two synchronous serial data ports.
Organization
This chapter consists of an overview of the product. Since the
DIDCSU 2912 can be used on either North American T1 circuits or
international E1 circuits, the remaining content of this manual is
divided accordingly.
Chapter 2, DIDCSU 2912 Quick Set-Up , presents two example
configurations, the first for the T1 mode and the second for the E1
mode.
Chapter 3, DIDCSU T1 Version , provides complete details on all the
T1 version administrative, configuration, performance and
diagnostic functions.
Chapter 4, DIDCSU E1 Version , provides complete details on all the
E1 version administrative, configuration, performance and
diagnostic functions.
Where the Verilink ASCII terminal interface (Craft interface) is
discussed, this manual assumes the module is used with an NCM
2000 Node Controller Module. The menus and options will be
similar when the module is accessed directly via the onboard
LOCAL
port.
The DIDCSU can operate as a standalone module or as part of an
NCM 2000 node. Circuits may be built between ports on DIDCSUs in
the same shelf only when an NCM is present. In the absence of an
NCM, the DIDCSU can be the shelf controller.
