Cabling
Use only CAT3 or better twisted-pair network connection cables for DSL
Termination Unit connections and interface patch cabling. Untwisted analog
cables of any length anywhere in the loop substantially contribute to crosstalk
and reduced loop reach.
The following customer-provided cables and cable adapters are required with
this product:
— Plug-ended Telco 50-pin cable for connection from the Hotwire 8610
DSLAM Line ports to the CO POTS splitter shelf or MDF, one cable per
DSL card.
— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection
to the DSL 10/100 BaseT Ethernet ports. You will need this cable for
accessing the LAN/WAN circuits of each DSL card.
— 8-pin UTP CAT5 modular cable for connection from the Hotwire 8610
DSLAM MANAGEMENT MCP port to a 10/100 BaseT hub connector
(connected to an SNMP management system network) for Slot 1 in the
base chassis. For other chassis in a stack, use this cable for daisy
chaining the chassis together. For M/HDSL and M/SDSL cards, refer to
the appropriate card Installation Instructions for the correct cable needed.
— 14-foot serial cable and DB25 and DB9 adapters are shipped with the
MCP card. For connection to a modem, you will need a NULL modem
adapter.
If there is adequate maintenance space at the rear of the rack, mount the
chassis on the rack before installing cables. If there is inadequate space to do
this, install the rear-mounted network connectors on the chassis before
mounting the chassis on the rack.
CAUTION:
Use of any nontwisted pair wiring arrangements, such as jumpers, can
cause reduction in overall DSL reach performance, even over short
distances.
NOTE:
Each Hotwire 8610 DSLAM chassis weighs approximately nine pounds (with
circuit cards) and can be easily installed by one installer.
