Hosted System Configuration
Configuring a hosted Compact Remote ATM DSLAM system

Note
All the configuration profiles reside on and are accessible only on the host
system.
You can also use the open command to access RLIMs directly from the host. Opening
a session to the resources of another unit in the hosted system is useful for diagnosing
error conditions, checking configurations, or performing certain maintenance
functions, but it cannot be used to provision the hosted system. For example, the
following command opens a session with the RLIM in slot 3 of remote shelf 2:
HOST>> open 2 3
dadsl-atm-24-2/3>
The open command can also be used on a remote shelf to open a session to the host.
For example, a repair or maintenance technician working at a remote site can open a
session to the host to inspect or change the configuration, run diagnostics, or perform
certain maintenance functions. In addition, once a session is open to the host, an
additional session can be opened from the host back to a remote LIM.
Configuring a hosted Compact Remote ATM DSLAM system
In a hosted system, the control module in the host is configured as the host controller
and the remote shelves operate in hosted mode. The host controller uses some of the
bandwidth of the 155Mbps optical link to a remote shelf for control messages to the
remote system resources—for example, to set up virtual circuits, update or create
profiles, and manage the remote LIMs (RLIMs). When a hosted COP receives control
messages from the host controller, it acts as proxy for the host controller and
forwards the messages to the proper RLIM.
The first steps in setting up a hosted system are to install the physical components
and cables. For details about installation, see earlier chapters in this guide. Following
the initial installation, the Compact Remote ATM DSLAM shelves come up in the
hosted mode, ready to communicate with the master controller over the 155Mbps
optical uplink. To configure the hosted system, you must complete the following
steps:
1
Configure the host unit to operate in host mode, then reset the host unit.
2
Identify the remote shelves in the hosted system.
3
Enable RLIM and host trunk interfaces.
4
Provision virtual circuits.
Optionally, you can also configure CAC procedures for the hosted system, and remote
shelf validation. For details, see "Traffic management in hosted Compact Remote
systems" on page 5-8, and "Configuring shelf validation" on page 5-13.
Configuring the host system to operate in master mode
To configure the controller in the host Stinger to operate as the master controller,
follow these steps:
1
If the host previously operated in standalone mode and does not already have a
multishelf boot loader installed, you must first perform an upgrade. (See, "Typical
hosted system upgrade procedure" on page 6-2, and "Hosted system upgrades
