OUT-OF-BAND UNITS

General

This chapter describes integrating out-of-band units into a VMS-controlled

satellite network.

Controlling Non-IP Modems

Before VMS can communicate with a non-IP capable modem, the modem must

have an IP-addressable unit, such as the Comtech CiM-25/600 or CiM-25/600L

attached and assigned a valid IP address using procedures described in the

appropriate product documentation, and described in the following procedure.

Modems such as the CDM-700, SLM-5650 or CDM-570 have a built-in Ether-

net interface and do not require an external CiM unit. Refer to these unit’s docu-

mentation for the procedure for assigning a valid IP address to the unit.

Note: Check the unit’s documentation for specific, detailed procedures.

Once a valid IP address has been assigned to target CiM-25, install the CiM-25

on its companion CDM-600L. The modem must then be declared in VMS using

the following procedure.

1. Connect the target CiM-25 unit to your workstation and assign a valid IP

address for the network where the CiM-25 and its companion CDM-600L

are to be installed

2. Reconnect the CiM-25 to its companion CDM-600L, then connect the eth-

ernet LAN and apply power as required.
