and synchronization circuit packs, a flashing FAULT LED shows that an incoming
signal to that circuit pack has failed. The green ACTIVE LED shows the current
protection switching states of the 1x1 protected circuit packs.
Craft Interface Terminal (CIT)
(Operations Tier 2)
9
The second operations tier provides access to DDM-2000 operations from a CIT
over an EIA-232-D interface. System details that can not be obtained from the first
operations tier alone can be obtained over the CIT interface. A VT-100 compatible
terminal or terminal emulator software running on a PC can be used as a CIT. The
dialog is settable to be either CCITT/ANSI MML-compliant, which provides both
prompt and command modes with extensive on-line help features for assistance in
command execution, or to an asynchronous TL1 interface.
The CIT interface supports OAM&P activities such as loopbacks and testing,
protection switching, provisioning, PM, retrieving reports, and security on any and
all DDM-2000 Multiplexers in a subnetwork from a single DDM-2000 or FT-2000.
The local DDM-2000 or FT-2000 CIT alarm reports may include far-end summary
alarm information about other Lucent NEs in the same subnetwork
*
. Access to
remote DDM-2000 Multiplexers is supported via CIT remote login.
The DDM-2000 FiberReach Multiplexer has a front access CIT port compatible
with the EIA-232-D standard. The front access port is configured as a data circuit
terminating equipment (DCE) for direct terminal access. The front CIT port
provides data rates of 300, 1200, 2400, 4800, 9600, and 19200 baud.
An optional graphical user interface (CPro-2000) software tool used with a PC is
also available.
— CPro-2000 is a Windows-based graphical user interface that allows a user
to obtain common graphical look-and-feel for DDM-2000,
SLC
-2000, and
FT-2000 products while continuing to have full access to the ASCII CIT and/
or TL1 interfaces of those SONET products. CPro-2000 also mechanizes
several tasks such as end-to-end path provisioning in path and line
switched rings and provides an NE database backup and restoral feature.
The CIT ports of the previously mentioned SONET products can be
accessed remotely over data networks and/or dial up modems.
Consequently, a user can access all Tier 2 operations using just a terminal
or CPro-2000 locally or remotely. See Chapter 10, "Technical
Specifications," for hardware and software needed to use CPro-2000. See
190-523-101 and/or 365-576-140,
CPro-2000 User Manual
, for more
information.
