Connecting the Components

Standalone COMSPHERE devices require a hubbing device to connect to the control channels.
This is explained in the following section.
All of these devices can be connected to the control channels, either locally or remotely. The two
sections following the description of the hubbing device explain how to connect these devices to
the control channels, both locally and remotely.
Using a Hubbing Device
For connection to a control channel, the COMSPHERE standalone devices must be equipped with
the hubbing device. The hubbing device permits multiple devices to be daisy chained together. The
hubbing device is not required for carrier-mounted devices.
Figure 4-13 shows an example of a control channel daisy chain.
To chain together COMSPHERE standalone devices to a control channel, perform the following
steps:
1. To start the daisy chain, connect the control channel to the modular jack marked
CCIN/DCOUT on the hubbing device connected to the first device.
2. To extend the daisy chain to the other devices, connect the cable from the CCOUT/DCIN
jack on the first hubbing device to the CCIN/DCOUT jack on the hubbing device
connected to the next device.
3. Continue to daisy chain devices in this manner, as necessary. You can daisy chain up to 256
devices in a single control channel.
DATAPHONE II and COMSPHERE devices can be daisy chained together on the same control
channel by connecting the CC-OUT jack on the DATAPHONE II modem chain to the
CCIN/DCOUT jack on the COMSPHERE hubbing device with an 035-0106-0531 cord or by
connecting the CCOUT/DCIN jack on the COMSPHERE hubbing device to the CC-IN jack on
the DATAPHONE II modem with an 035-0107-0531 cord.
