What is a Hotwire Shelf Concentration Module?  
A Hotwire® Shelf Concentration Module (SCM) is a circuit card assembly (CCA)  
that contains a parentcard with an ATM switch, a backplane interface, a processor,  
a cell mux/demux, and an uplink childcard. The childcard determines the type of  
ATM uplink supported by the SCM.  
When the SCM card is used in a Hotwire 8820 GranDSLAM chassis, it aggregates  
DSL traffic from each of the DSL port cards in the chassis on the chassis’  
backplane bus and concentrates it onto an ATM interface. The model number of  
the SCM card differs, depending on what type of ATM uplink childcard is being  
used.

Installing the SCM Card  
Procedure  
To install the Hotwire SCM Card in Slot A of the GranDSLAM chassis:  
1. If there is a filler plate covering the slot, remove it.  
2. Remove the yellow screw covers.  
3. Insert the card into the card guides of the slot on the chassis.  
4. Carefully slide the card into the slot. Lift the insertion/ejection levers away from  
the faceplate until the card begins to engage the connectors on the backplane.  
Then press in on the insertion/ejection levers until the card is fully seated.  
5. Verify that the OK SYSTEM indicator on the card’s faceplate is ON (winking  
green). If not, refer to the appropriate Hotwire GranDSLAM Installation Guide.  
6. Secure the card by fastening the screws on each end of the faceplate. This is  
required to maintain proper gasket pressure on the faceplate as well as proper  
air flow.  
7. Attach appropriate connections (e.g., DS3, OC3, etc.) to the uplink.  
NOTE:  
The IMA uplink has a RJ48M 50-pin connector. See IMA Uplink Card  
Connector Pinouts on page 4 for more information.

IMA Uplink Card Connector Pinouts  
The IMA uplink has a RJ48M 50-pin Telco connector with 8 Tip/Ring and  
8 Tip1/Ring1 connections that conforms to ANSI T1.403-1999. Paradyne offers an  
octopus cable for use with the IMA uplink (Feature No. 8026-F1-001 for Models  
8026 and 8028, and Feature No. 8027-F1-001 for Model 8027). These cables  
contain a required ferrite to meet EMI requirements. If purchasing other Telco  
cables, you must attach the supplied ferrite and cable tie as shown below. Contact  
your service representative for more information.  
When connecting the Telco cable, a .87-inch long panhead screw and cable tie  
must be used to mount the cable to the 50-pin Telco connector as shown below.
