Test System 2000 Release Notes 3
Figure 1 Example Configuration of the TS2000 testing a remote CSU/DSU far-end node
TS2000 test set code is downloaded to a TAC host element either via a
direct connection or via a modem connection. The circuit under test is a
T1 circuit between the TAC and a remote CSU. The TS2000 can test the
circuit in the network direction (toward the remote CSU) or in the
equipment direction (toward the DSX attached to the test element side of
the T1 circuit). TS2000 can put up loopbacks at the far-end or near-end. It
can also allow itself to be put into local loopback mode and receive test
patterns or errors injected from a standalone test set at the far-end. If the
far-end is an AS2000, TS2000 test set code can be installed there also, so
that the circuit can be tested from the reverse direction via modem.
Compatibility and
requirements The following requirements are needed to run the Test System 2000:
■
AS2000 with an NCC 2020 or TAC 2010.
■
The Controller RAM chip (SAM) on the NCC plug-in module (P/N
489-501838-xxx must be at the revision level of V 4.51 or higher.
Your TS2000 product shipment inventory includes a firmware
download from the AS2000 Release 1.5 that brings the Controller
RAM chip up to V 4.61.
(For details on Release 1.5, see AS2000 Release 1.5 Upgrade
Instructions.)
(You can locate the Revision number by using the AM2000. For
details, see Access Manager 2000 User Manual.)
