4. Verify that primary timing on both CM4s are setup for “THRU” (TIME group)
5. Verify the fallback timing on both CM4s are setup for “Floo” (FTIM group under
Supplementary Configuration Group)
6. Verify that the “TYPE” on both CM4s are setup for “T1”, the “HEAD” are setup for “120” and
the “TLBO” are setup for “0x00” (INTF group).
7. Obtain the network configuration file for your network. This file is usually prepared by RFL
but can be prepared by the user.
The network configuration file actually consists of multiple files of the same name, with
various extensions, which, if moved or copied, must be kept in a common directory or folder.
The file with the .NET extension is the top level file of the set.
Launch NMS and open the network configuration file for your application by selecting the
appropriate .NET file.
Using the IMUX 2000 Network Management Software (NMS), download the configuration
and status information of the DACS module and the CM4 modules from the M-DACS
multiplexer at location 1.
(See section 5 of this manual for more information on how to use NMS)
Verify that the settings for the DACS module and the CM4 modules are as required:
Once the configuration information is read, return to the NMS main screen. Click
on the REPORTS button and select the DIFFERENCE REPORT. This report lists
configuration items, which differ between the actual value in the file and the actual
value in the device.
8. Use the following method to establish a local T1 loopback at the T1 port (1) on the M-DACS:
If the M-DACS multiplexer is equipped with an electrical T1 Line I/O interface, connect an
external loopback plug to the RJ-48C female T1 connectors on the MA-260 Module Adapter or
to the 9-pin D-subminiature T1 connector (DB-9) on the MA-261 Module Adapter.
If the M-DACS multiplexer is equipped with a fiber optic interface, connect a fiber optic patch
cord between the fiber optic connectors (TX and RX) on the Optical Interface Adapter (OIA).
9. Once the loopback is established, verify the states of the following indicators on the DACS
module and on both CM4s in Table 7-1 (See Figure 7-8 for CM4 front panel status indicators).
Using NMS, verify that the DACS module is not in ALERT or ALARM (See Section 5 of this
manual for more information on how to use NMS).
