What is a Hotwire Shelf Concentration Module?
®
A Hotwire
that contains a parentcard with an A T M 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 awa y 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
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.
