communicate on your network. You should now be able to communicate with both CM-30R modules
using your own assigned IP addresses instead of using the factory default IP addresses.
A.2.5
Configuration of Both CM-30R Modules to Work Together
Configuring the two CM-30R modules to take over operation of the T1/E1 multiplexers and thus
convert the multiplexers to IP systems involves these processes:
1.
Confirm that the channel modules installed in the multiplexer match the channel modules that the
CM-30R module registers.
2.
Map the installed channel modules and services across the IP network.
3.
Establish a synchronous operation.
4.
Confirm the network operations.
A.2.5.1 Confirm the Installed Channel Modules Match the CM-30R Registers
Access the
Home
page of each NetXpress LX/ CM-30R Web interface to confirm the CM-30R module
registers the presence of the installed channel modules. The CM-30R module registers any installed
channel modules set to Remote Control mode and previously configured for operation by the T1/E1
controller. Once the T1/E1 controller releases control of the multiplexer shelf to the CM-30R module,
you can use the CM-30R module to control and configure the channel modules.
While the CM-30R module is in
Learning
mode
, it does not register installed channel modules that are
manually configured and set to Local Control mode, but these modules do appear on the
Home
page
once the CM-30R module becomes the primary controller. Manually configured modules can still use
the TDM bus for sending and receiving data. When the REMOTE switch of a channel module is set to
the right (
up
, or away from the circuit board), the module is in Local Control mode. To permit the CM-
30R module to start learning about these installed modules as well, enable the Remote Control mode
on each channel module by carefully setting the modu
le’s REMOTE switch to the left (
down
, or toward
the circuit board).
If there is an additional module showing on the CM-30R interface
Home
page that is
not actually
present
in your multiplexer, that module is stored in the CM-30R
system’s memory. To clear o
ut the
memory history and restart the scan, perform these steps:
1.
On the
NetXpress LX
(CM-30R)
Home
page, go to
System Cfg
|
Configuration Backup
.
2.
On the
Configuration Files Backup/Restore
table, click
on the
/RFA/cfg/scbdata.cfg
row to delete the scbdata.cfg file. The delete confirmation dialog box appears.
3.
Click
OK
to confirm deleting the configuration file.
4.
Click
Reset the System
. The system reset confirmation dialog box appears.
5.
Click
OK
to confirm resetting the system.
If the modules appearing on the
Home
page now match the modules installed in your multiplexer, the
CM-30R module has completed the learning process.
A.2.5.2 Map the Installed Services
The data from channel modules in each multiplexer is mapped across the Ethernet network to
matching channel modules in another multiplexer using data
streams
. Each stream entry defines the
IP packet size, the destination IP address, the TDM bus and the range of TDM time slots for a channel
module or group of adjacent modules.
On the Web interface, add entries to the
Streams
table to send and receive the TDM data for each of
your installed channel modules (Section 4.3.5
–
Configure Streams
). Create streams with low latency
and signaling support to use with the telephony (VF-) modules and streams without signaling to use
with transporting data (DA- and DS-) modules. You can review the TDM bus selection, the starting
