InBand Circuit

An InBand circuit refers to a circuit which has its control channel within the

same band as the communication channels. In figure 3-16, SCPC and STDMA

In-Band circuits are shown for a Vipersat network using CDM-570L modem/

routers.

Figure 3-16

InBand Circuit diagram

This type of connection applies to circuits which utilize Comtech EF Data

modem devices containing an integral IP router (Viperized).

Out-of-Band Circuit

An Out-of-Band circuit applies when a configuration similar to the one shown

in figure 3-17 is used to establish a high-speed data link between non-Vipersat

units such as the CDM-600L and its companion CiM-25 IP module. The

management and control commands from the VMS are transmitted and received

InBand by the CDM-570L circuit. These commands are then routed by the

CDM-570L over Ethernet to the CDM-600L modem.

Since the management and control signals are handled by the CDM-570L

within its allocated bandwidth and do not occupy any of the CDM-600L’s band-

width, these command circuits are considered Out-of-Band with respect to the

CDM-600L circuit.
