Prior to Installing the CSU/DSU
These Installation Instructions assume that the virtual circuits at the DSLAM have
already been configured. Provisioning of these circuits can be simplified by using the
OpenLane SLM (Service Level Management) system, as indicated in
Provisioning Data
Circuits in OpenLane .
Provisioning Data Circuits in OpenLane
Use the OpenLane SLM system’s Provision Circuit screen to add new circuits that start
at the FrameSaver DSL endpoint and traverse the SCM and ATM line card in the Hotwire
GranDSLAM, and the default VC sets(from 1 to 4). A group of 250 VCs can be allocated
to each line card, which can be assigned to any port on the card. These custom
connections carry the frame relay traffic.
 Note that before the custom cross-connects are configured, the Maximum VCI
number for the uplink VP to be used by these custom connections must be
specified on the Max VCI per VPI screen, and the apply changes executed.
 For ATM line cards, custom connections can be used to expand the number of VCs
connected to the card. Each of the 250 VCs can be cross-connected from any VC
on the uplink to any port on the line card.
The following information is collected by the Provision Circuit process:
 Uplink VPI/VCI
 Slot number and Port number of the DSL connection
 Traffic Profile
 DSL link VPI/VCI
 Frame relay DLCI (provided by NSP)
 Frame relay CIR, Be, Bc(provided by NSP)
A Circuit ID is then applied to the newly defined circuit, and stored in both the CSU/DSU
and the OpenLane SLM system.

6
Installing the CSU/DSU
Place the FrameSaver DSL 9783 CSU/DSU on a flat surface with clearance for the rear
connectors.
Procedure
1. Use the supplied 8-pin DSL network cable (for use in the U.S.), or a 6-pin DSL
network cable (using connectors similar to RJ11), as applicable, for the DSL
connection. Insert one end of the cable into the jack labeled NET. Insert the other
end into the wall jack for DSL data communications.
For domestic models, go to Step 3 on page 7.
2. For certain international models, a ferrite
