Appendix A – T1/E1-to-NetXpress LX
This appendix covers the CM-30 package installation, configuration, and troubleshooting for converting
your T1 or E1 Intraplex multiplexers into NetXpress LX multiplexers. This discussion assumes that you
are working with a 3-rack unit (3RU) 19-inch multiplexer shelf.
To minimize system downtime, you may install your CM-30 modules while your Intraplex multiplexers
are powered up (power is on). The CM-30 IP interface module begins "learning" the channel module
information from the existing common module while still operating in T1 or E1 mode, prior to live
operation over the IP network.
There are six basic processes in this conversion:
1. CM-30 and MA-230 installation in the first multiplexer
2. Network configuration of the CM-30 module in the first multiplexer
3. CM-30 and MA-230 installation in the second multiplexer
4. Network configuration of the CM-30 module in the second multiplexer
5. Configuration of the two CM-30 modules to work together
6. Removal of the original common modules from the multiplexers
You must perform these processes in order and in the manner specified in this appendix to
successfully convert your Intraplex multiplexers to NetXpress LX IP multiplexers. Therefore, read all of
these processes, procedures, and guidelines before proceeding to insert the CM-30 modules and the
MA-230 module adapters into your T1/E1 multiplexer shelves.
Be aware that Alert and Alarm conditions appear on the multiplexer during the update process. If you
have an alarm or remote control system wired to the external relay contacts of the multiplexer, you
might wish to disable the alarm system before proceeding with the installation.
A.1 Installation Preparation
A.1.1 Equipment Unpacking & Inspection
Upon receiving your CM-30 package, complete these tasks:
1. Inspect all shipping containers for damage. If you observe damage, notify the shipping service as
soon as possible.
2. Unpack all equipment from containers.
3. Inspect equipment for damage.
4. Verify that the CM-30 package is equipped as expected, confirming items from the packing list
(Bill of Materials):
• Two (2) CM-30 NetXpress LX IP common modules in good condition
• Two (2) MA-230 NetXpress LX IP module adapters in good condition
