Hotwire Shelf Concentration and Processing Card

A Hotwire® Shelf Concentration and Processing (SCP) card is a circuit card
assembly that comprises a parent card with an ATM switch, a backplane interface,
a processor, a cell multiplexer/demultiplexer, and an uplink childcard. The
childcard determines the type of ATM uplink supported by the SCP card.

When the SCP card is used in a Hotwire 8620 or 8820 GranDSLAM chassis, it
aggregates DSL traffic from each of the DSL port cards in the chassis on the
chassis’s backplane bus and concentrates it onto an ATM interface. The following
models are available:

SCP Card Model ATM Uplink Childcard

8411-A1-000 DS3

8412-A1-000 OC3/STM1 Multimode Fiber

8413-A1-000 OC3/STM1 Single Mode Fiber Intermediate Reach (15 km)

8414-A1-000 OC3/STM1 Single Mode Fiber Long Reach (40 km)

8416-A1-000 8-Port DS1 IMA (Inverse Multiplexing over ATM)

8417-A1-000 8-Port E1 IMA

The SCP card supports the following line cards:

 8955 ReachDSL ATM Card

 8965 ADSL ATM Card

 8985 SHDSL ATM Card

With a Management Communications Controller (MCC) card installed in the same
chassis, the SCP card also supports Hotwire Time Division Multiplexer (TDM)
SDSL and SHDSL cards, Models 8775, 8777, 8779, and 8799.

4. Carefully slide the card into the slot until the card meets the connectors on the
backplane. Then press in on the insertion/ejection levers until the card is fully
seated.

5. Verify that the SYSTEM Active or Standby indicator on the card’s faceplate is
cycling off and on. See SCP Card LEDs on page 8.

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 to the uplink. These are described in the
following sections:

— DS3 Uplink on page 5

— OC3 Uplink on page 6

— IMA Uplink on page 7

Installing Two SCP Cards in the Same DSLAM

Two SCP cards may be installed in one DSLAM to provide redundancy or load
sharing. There are three basic configurations for paired SCP cards:

 Y-Cable – The OC3 ports of the two SCP cards are connected to the same

uplink device. If the active SCP card fails, the backup SCP card automatically
becomes the uplink. See Equipment List on page 15 for available Y-cables.

 Dual Link – Automatic switching occurs in the event of failure, but the SCP

cards are connected to different uplink devices.

 Load Sharing – Both SCP cards are active, and connected to different uplink

devices. In the event of the failure of one of the cards, Dual Link redundancy
must be manually enabled.

If you use two SCP cards configured for redundancy, and intend to manage the
chassis through the active card’s Ethernet port, each card must have its own
connection to your hub (through the connector marked LAN Slot A or B). The cable
cannot be switched after the backup SCP card becomes the active card. Also,
since the two SCP cards share the same MAC address, they cannot both be
connected to switch ports on your Ethernet switch.

SCP cards with a DS3 uplink have two BNC jacks: one for the transmit direction
and one for the receive direction. To cable an SCP card with an DS3 uplink:

1. Connect the input cable to the RX jack on the faceplate of the SCP card.

2. Connect the output cable to the TX jack on the faceplate of the SCP card.

3. If the chassis is mounted in a rack, direct the cables toward the nearest rail
and fasten them with cable ties.

OC3 Uplink

SCP cards with an OC3 uplink use an SFP transceiver that accepts an LC-type
connector. To cable an SCP card with an OC3 uplink:

1. Remove the plastic dustcover from the SFP socket.

2. Insert the LC connector of your fiber optic cable into the SFP socket.

3. Observing the minimum bend radius for your cable, fasten it with cable ties in
such a way that it will not be kinked or snagged in the course of other cabling.
If you do not know the specifications for your cable, maintain a radius of at
least ten times the cable diameter.
